A common type of oil trap is:
- A.
Salt dome
- B.
Anticline
- C.
Fault trap
- D.
All of the above
Correct Answer
D. All of the aboveExplanation
The correct answer is "all of the above" because all three options - salt dome, anticline, and fault trap - are commonly known types of oil traps. Oil traps are geological formations or structures that prevent the upward migration of oil and gas, causing them to accumulate in a reservoir. Salt domes, anticlines, and fault traps are all examples of such formations that can trap oil and gas underground, making them important targets for oil exploration and production.Rate this question:

All of the following are young mountain belts except:
- A.
North American Cordillera
- B.
Himalayas
- C.
Appalacians
- D.
Alps
Correct Answer
C. AppalaciansExplanation
The Appalachian Mountains are not considered a young mountain belt because they were formed around 480 million years ago during the Paleozoic era. They have since undergone significant erosion and are now considered a mature mountain range. In contrast, the North American Cordillera, Himalayas, and Alps are all considered young mountain belts because they are still actively being uplifted and are geologically active.Rate this question:

A tenfold increase in wave amplitude corresponds to an increase of ____ on the magnitude scale.
- A.
5
- B.
1
- C.
10
- D.
32
Correct Answer
B. 1Explanation
A tenfold increase in wave amplitude corresponds to an increase of 1 on the magnitude scale. This means that the magnitude of the wave increases by a factor of 1 when the amplitude increases by a factor of 10. The magnitude scale is logarithmic, so each unit increase represents a tenfold increase in wave amplitude. Therefore, a tenfold increase corresponds to an increase of 1 on the magnitude scale.Rate this question:

Occording to the Nebular Theory, our solar system is ______ years old.
- A.
13.7 billion
- B.
3.6 billion
- C.
542 million
- D.
4.6 billion
Correct Answer
D. 4.6 billionExplanation
According to the Nebular Theory, our solar system is believed to be 4.6 billion years old. This theory suggests that the solar system formed from a giant rotating cloud of gas and dust known as the solar nebula. Over time, this nebula collapsed under its own gravity, forming a spinning disk. The Sun formed at the center of this disk, while the remaining material came together to form the planets, moons, asteroids, and comets. By studying the ages of the oldest rocks on Earth and moon samples brought back by astronauts, scientists have determined that the formation of our solar system occurred approximately 4.6 billion years ago.Rate this question:

Earthquakes can be as deep as:
- A.
300km
- B.
700km
- C.
1,000km
- D.
500km
Correct Answer
B. 700kmExplanation
Earthquakes can occur at various depths within the Earth's crust and upper mantle. The correct answer of 700km suggests that earthquakes can reach depths of up to 700 kilometers. These deep earthquakes are typically associated with subduction zones, where one tectonic plate is being forced beneath another. The intense pressure and friction at these depths can lead to the release of seismic energy, resulting in earthquakes. It is important to note that shallow earthquakes, occurring within the upper 20 kilometers of the Earth's surface, are more common and often more destructive.Rate this question:

Mountain height is limited by all of the following except:
- A.
Deposition
- B.
Erosion
- C.
Isostasy
- D.
Gravitational collapse
Correct Answer
A. DepositionExplanation
Mountain height is limited by erosion, isostasy, and gravitational collapse. Deposition, on the other hand, refers to the process of sediment or other materials being added to a landform. This can actually contribute to the growth and height of a mountain over time. Therefore, deposition does not limit mountain height, making it the correct answer.Rate this question:

Accreted crustal blocks that have geologic history distinct from the adjoining crustal blocks:
- A.
Terrane
- B.
Crust
- C.
Continent
Correct Answer
A. TerraneExplanation
A terrane refers to accreted crustal blocks that have a geologic history distinct from the surrounding or adjoining crustal blocks. These blocks may have different rock types, ages, or tectonic histories compared to the surrounding crust. Terranes are often the result of tectonic processes like subduction, where pieces of crust are scraped off one tectonic plate and added to another. The concept of terranes helps geologists understand the complex history and evolution of Earth's crust, particularly in areas where multiple tectonic plates have interacted.Rate this question:

Each drainage basin is bounded by an imaginary line called a:
- A.
Rill
- B.
Mouth
- C.
Divide
- D.
Pothole
Correct Answer
C. DivideExplanation
A drainage basin is a geographical area where all the water from rainfall or snowmelt drains into a common outlet, such as a river or lake. The boundary of a drainage basin is called a "divide." This divide separates one drainage basin from another, determining the direction in which water flows. It is an imaginary line that marks the highest point or ridge where water on one side flows into one basin, while water on the other side flows into a different basin. Therefore, the correct answer is "divide."Rate this question:

Which of the following is not a major province of the ocean floor?
- A.
Abyssal plain
- B.
Continental margin
- C.
Deep-ocean basin
- D.
Mid-ocean ridges
Correct Answer
A. Abyssal plainExplanation
The abyssal plain is not a major province of the ocean floor. The ocean floor is divided into several major provinces, including the continental margin, deep-ocean basin, and mid-ocean ridges. The abyssal plain, on the other hand, is a flat, sediment-covered region of the ocean floor that lies between the continental margin and the mid-ocean ridges. While it is an important feature of the ocean floor, it is not considered one of the major provinces.Rate this question:

The “D” layer is significant in plate tectonics because:
- A.
The lithosphere glides on its weak zone
- B.
It is the graveyard of subducted lithosphere
- C.
Magma from the D layer rises to the surface
- D.
The “D” layer plays a major role in transform faults
Correct Answer
B. It is the graveyard of subducted lithospHereExplanation
The "D" layer is significant in plate tectonics because it is the graveyard of subducted lithosphere. This means that when one tectonic plate is forced beneath another in a process called subduction, the subducted lithosphere sinks into the mantle and accumulates in the D layer. This layer acts as a repository for the remnants of subducted lithosphere, providing valuable evidence of past tectonic activity. By studying the composition and characteristics of the D layer, scientists can gain insights into the history and dynamics of plate tectonics.Rate this question:

Where are most caverns formed? a) b) below the water table c) underwater d) in outer space
- A.
Above the water table
- B.
Below the water table
- C.
Underwater
- D.
In outer space
Correct Answer
B. Below the water tableExplanation
Caverns are most commonly formed below the water table. The water table is the level below the Earth's surface where the ground is saturated with water. When water seeps through the ground and dissolves soluble rock, such as limestone, it creates underground voids and passages. Over time, these voids can grow larger and form caverns. The water table provides the necessary conditions for the formation of caverns as it allows for the movement of water and the dissolution of rock.Rate this question:

Which of the following has normal faulting?
- A.
The Himalayas
- B.
Basin and Ridge Province
- C.
Japan
- D.
San Andreas
Correct Answer
B. Basin and Ridge ProvinceExplanation
The Basin and Ridge Province has normal faulting. Normal faulting occurs when the hanging wall moves downward relative to the footwall. In the Basin and Ridge Province, the crust has been stretched and thinned, causing the rocks to break and slide along normal faults. This type of faulting is characteristic of areas undergoing tensional stress, such as the Basin and Ridge Province, where the crust is being pulled apart. The other options, the Himalayas, Japan, and the San Andreas, are associated with other types of faulting, such as thrust faulting, subduction zone faulting, and strike-slip faulting, respectively.Rate this question:

The elastic rebound theory explains how:
- A.
Earthquakes occur
- B.
Rocks spring back into their original position
- C.
Faults rupture
- D.
Foreshocks occur
Correct Answer
B. Rocks spring back into their original positionExplanation
The elastic rebound theory explains that when stress builds up along a fault line, the rocks on either side of the fault are deformed and stored with potential energy. Eventually, the stress becomes too great and the rocks rupture, releasing the stored energy. As the rocks break and slip past each other, they spring back into their original position due to their elastic properties. This sudden release of energy is what causes an earthquake.Rate this question:

During metamorphism, what changes might take place in a rock?
- A.
Minerology
- B.
Texture
- C.
Chemical composition
- D.
All of the above
Correct Answer
D. All of the aboveExplanation
During metamorphism, all of the mentioned changes can occur in a rock. Metamorphism refers to the process in which rocks undergo physical and chemical changes due to high pressure, temperature, and fluid activity. These changes can result in alterations in the mineralogy, texture, and chemical composition of the rock. Different minerals may form or recrystallize, the texture can become more foliated or granular, and the chemical composition may be modified through the addition or removal of elements. Therefore, all of these changes are possible during metamorphism.Rate this question:

About 410km deep in Earth’s interior, a soft, weak layer exists. This is called the ___________.
- A.
Asthenosphere
- B.
Lithosphere
- C.
Transition zone
- D.
Mantle
Correct Answer
A. AsthenospHereExplanation
The correct answer is asthenosphere. The asthenosphere is a soft, weak layer located about 410km deep in Earth's interior. It is composed of partially molten rock that allows the lithospheric plates to move and slide on top of it. This layer is responsible for the movement of tectonic plates and plays a crucial role in shaping the Earth's surface through processes like plate tectonics and volcanic activity.Rate this question:

Glass is not a mineral because:
- A.
It is not a solid
- B.
It lacks a well-defined chemical composition
- C.
It is organic
- D.
It lacks a repetitive atomic structure
Correct Answer
D. It lacks a repetitive atomic structureExplanation
Glass is not a mineral because it lacks a repetitive atomic structure. Minerals are naturally occurring inorganic solids with a definite chemical composition and a regular, ordered arrangement of atoms. Glass, on the other hand, is an amorphous solid, meaning it does not have a regular, repeating pattern of atoms. It is formed when molten material cools rapidly, preventing the atoms from arranging themselves into a crystalline structure. Therefore, glass does not meet the criteria to be classified as a mineral.Rate this question:

Correct Answer
B. Protons, neutronsExplanation
Isotopes are atoms of the same element that have the same number of protons (which determines the element) but different numbers of neutrons. This means that isotopes have the same number of electrons as an element, as the number of electrons is equal to the number of protons in a neutral atom. However, the number of neutrons can vary among isotopes, resulting in different atomic masses.Rate this question:

This principle of relative dating states that rocks embedded in another rock are older than the rock that surrounds them.
- A.
Law of superposition
- B.
Principle of inclusion
- C.
Law of cross-cutting relationships
- D.
Original horizontality
Correct Answer
B. Principle of inclusionExplanation
The principle of inclusion states that rocks or fragments of rocks found within another rock are older than the rock that contains them. This is because the rock containing the fragments must have formed after the fragments were already present. Therefore, if a rock is found to have embedded rocks within it, those embedded rocks must be older than the surrounding rock.Rate this question:

The opening of a new basin (for example The Red Sea) begins with the formation of a: a) mountain range b) volcano c) continental rift d) mid-ocean ridge
- A.
Mountain range
- B.
Volcano
- C.
Continental rift
- D.
Mid-ocean ridge
Correct Answer
C. Continental riftExplanation
The opening of a new basin, such as the Red Sea, begins with the formation of a continental rift. A continental rift occurs when the Earth's crust starts to pull apart, creating a gap or rift. This rift allows magma from the mantle to rise to the surface, forming a volcano. Over time, the continued separation of the crust creates a larger gap, leading to the formation of a mountain range. Finally, as the crust continues to separate, a mid-ocean ridge is formed, marking the opening of a new basin.Rate this question:

A common feature for a passive margin is:
- A.
Earthquakes
- B.
Volcanoes
- C.
Large continental shelf
- D.
Deep-ocean trench
Correct Answer
C. Large continental shelfExplanation
Passive margins are found along the edges of tectonic plates where there is no significant tectonic activity. These margins are characterized by a large continental shelf, which is a gently sloping extension of the continent into the ocean. This shelf is created by the accumulation of sediment over millions of years. Unlike active margins, passive margins do not have volcanoes or deep-ocean trenches, as there is no subduction or volcanic activity occurring. Therefore, the presence of a large continental shelf is a common feature for passive margins.Rate this question:

In which environment could liquefaction occur?
- A.
Desert
- B.
Forest
- C.
Coastal cities
- D.
Caves
Correct Answer
C. Coastal citiesExplanation
Liquefaction is a phenomenon that occurs when saturated soil loses its strength and behaves like a liquid during an earthquake or other seismic activity. Coastal cities are more prone to liquefaction because they are often built on loose, sandy soils or reclaimed land, which can easily become saturated with water. The combination of loose soil and the presence of water increases the likelihood of liquefaction happening during an earthquake, making coastal cities more vulnerable to this phenomenon.Rate this question:

The Big-bang theory explains:
- A.
The origin of the universe
- B.
How the solar system formed
- C.
The formation of Earth
- D.
Evolution of species
Correct Answer
A. The origin of the universeExplanation
The Big Bang theory is a scientific explanation for the origin of the universe. It proposes that the universe began as a singularity, a tiny, hot, and dense point, approximately 13.8 billion years ago. This singularity then rapidly expanded and continues to expand, resulting in the formation of galaxies, stars, and other celestial bodies. The theory is supported by various pieces of evidence, such as the observed cosmic microwave background radiation and the redshift of distant galaxies. It does not explain the formation of the solar system, the Earth, or the evolution of species, as those are separate scientific theories and processes.Rate this question:

Which of these rocks in nonfoliated?
- A.
Marble
- B.
Phyllite
- C.
Mica schist
- D.
Slate
Correct Answer
A. MarbleExplanation
Marble is a nonfoliated rock because it does not exhibit any foliation or layering. It is formed from the metamorphism of limestone or dolomite, and its crystals are randomly oriented, giving it a uniform and non-layered appearance. Unlike phyllite, mica schist, and slate, which are all foliated rocks, marble does not show any alignment of minerals or bands. Therefore, marble is the correct answer as a nonfoliated rock.Rate this question:
