Which is not a land resource?
- A.
Soil
- B.
Land
- C.
Forests
- D.
Wind
Correct Answer
D. WindExplanation
Wind is not considered a land resource because it is an atmospheric resource. Land resources typically refer to the physical features and materials found on land, such as soil, forests, minerals, and water bodies. Wind, on the other hand, is a natural movement of air in the atmosphere and is not directly associated with the land itself. While wind can have an impact on land and its use, it is not classified as a land resource.Rate this question:

After an igneous rock has formed, it can either
- A.
Be broken down into sediements
- B.
Turn into extrusive rock
- C.
Be heated and compacted into metamorphic rock
- D.
Both a and c
- E.
Both b and c
Correct Answer
D. Both a and cExplanation
After an igneous rock has formed, it can be broken down into sediments through the process of weathering and erosion. This occurs when the rock is exposed to the elements and undergoes physical and chemical changes that cause it to break apart. Additionally, the igneous rock can also be heated and compacted under extreme pressure to form metamorphic rock. This transformation occurs deep within the Earth's crust where high temperatures and pressure cause the minerals in the rock to rearrange and form a new type of rock. Therefore, both options a and c are correct.Rate this question:
-
- 6.
Metamorphic rocks are formed from _______ from the Earth's core and _______ from other rocks.
Correct Answer
heat and pressureExplanation
Metamorphic rocks are formed through the process of metamorphism, which involves the transformation of existing rocks under high temperatures and pressures. The heat and pressure cause the minerals in the rocks to recrystallize and form new minerals, resulting in the formation of metamorphic rocks. Therefore, the correct answer is "heat and pressure."Rate this question:

Sedimentary rocks are formed from ______ and _______.
- A.
Compaction and cementation
- B.
Cementation and fossilization
- C.
Erosion and weathering
Correct Answer
A. Compaction and cementationExplanation
Sedimentary rocks are formed through a process that involves the accumulation of sediments, which are particles of rocks, minerals, and organic matter. Compaction refers to the process in which the weight of overlying sediments compresses the layers beneath, reducing the pore space and causing the sediments to become more tightly packed. Cementation, on the other hand, occurs when minerals precipitate and fill the remaining pore spaces, binding the sediments together into a solid rock. Therefore, sedimentary rocks are formed from the processes of compaction and cementation.Rate this question:

These particles are involved in atom bonding.
- A.
Protons
- B.
Neutrons
- C.
Electrons
- D.
Isotopes
Correct Answer
C. ElectronsExplanation
Electrons are involved in atom bonding. They are negatively charged particles that orbit around the nucleus of an atom. During bonding, electrons are either shared or transferred between atoms to form chemical bonds. This process allows atoms to achieve a stable electron configuration, similar to the noble gases, and create compounds. Protons and neutrons, on the other hand, are found in the nucleus of an atom and do not directly participate in bonding. Isotopes, while related to atoms, do not play a direct role in atom bonding.Rate this question:

_______- the same processes that happen today happened millions of years ago.
Correct Answer
UniformitarianismExplanation
Uniformitarianism is the belief that the same geological processes that occur today have been occurring throughout Earth's history. This means that the processes that shaped the Earth millions of years ago, such as erosion, volcanic activity, and plate tectonics, are the same processes that continue to shape the Earth today. This theory is based on the idea that the laws of nature have remained constant over time. It is supported by evidence from the geological record and has been a fundamental principle in the field of geology.Rate this question:
- 14.
_______- states that, in an undisturbed area of rock, the layer of rock at the bottom of the area is the oldest.
Correct Answer
law of superpositionExplanation
The law of superposition states that, in an undisturbed area of rock, the layer of rock at the bottom of the area is the oldest. This principle is based on the observation that, over time, sedimentary rock layers are deposited one on top of another, with the oldest layers at the bottom and the youngest layers at the top. By studying the sequence of rock layers, scientists can determine the relative ages of the rocks and the fossils they contain. This principle is fundamental in the field of geology and helps scientists understand the history of the Earth's surface.Rate this question:

Which waves create the most surface damage?
- A.
Surface waves/land waves
- B.
P-waves
- C.
S-waves
Correct Answer
A. Surface waves/land wavesExplanation
Surface waves, also known as land waves, create the most surface damage. These waves are generated by seismic activity, such as earthquakes, and they travel along the Earth's surface. Surface waves cause the ground to move in a rolling motion, resulting in significant damage to buildings, infrastructure, and the surface of the Earth. P-waves and S-waves, on the other hand, are body waves that travel through the Earth's interior and cause less surface damage compared to surface waves.Rate this question:

Where do mid-ocean ridges occur? Choose the best answer.
- A.
Divergent plate boundaries
- B.
In the ocean
- C.
Convergent plate boundaries
- D.
Transform plate boundaries
Correct Answer
A. Divergent plate boundariesExplanation
Mid-ocean ridges occur at divergent plate boundaries. Divergent plate boundaries are locations where two tectonic plates are moving away from each other. This movement creates a gap between the plates, allowing magma from the mantle to rise up and form new oceanic crust. As the magma cools and solidifies, it creates a ridge-like structure on the ocean floor. These mid-ocean ridges can be found in various parts of the world's oceans, such as the Mid-Atlantic Ridge and the East Pacific Rise.Rate this question:
