Earth's outermost layer is the _________________.
- A.
Core
- B.
Crust
- C.
Mantle
- D.
Plate
Correct Answer
B. CrustExplanation
The Earth's outermost layer is known as the crust. It is the solid, rocky shell that forms the Earth's surface. The crust is relatively thin compared to the other layers of the Earth, such as the mantle and the core. It is divided into two types: the continental crust, which makes up the continents, and the oceanic crust, which forms the ocean floors. The crust is where most geological activity occurs, including the formation of mountains, volcanoes, and earthquakes.Rate this question:

A vocano can fall in on itself, creating a large basin called ________________.
- A.
A crater
- B.
An epicenter
- C.
A fault
- D.
A plate
Correct Answer
A. A craterExplanation
When a volcano collapses inward, it forms a large basin called a crater. This occurs when the pressure from the eruption decreases and the volcano's structure cannot support itself, causing the top part to collapse and form a depression. Craters are typically circular in shape and can vary in size depending on the size and intensity of the volcano. They are often seen at the summit or on the sides of volcanoes and are formed as a result of explosive volcanic activity.Rate this question:

A break in the Earth's crust along which rocks move is called __________.
- A.
An eathquake
- B.
An epicenter
- C.
A fault
- D.
A volcano
Correct Answer
C. A faultExplanation
A break in the Earth's crust along which rocks move is called a fault. Faults occur when there is stress and strain on the Earth's crust, causing it to crack and shift. These movements can result in earthquakes as the rocks on either side of the fault slip past each other. Faults are important geological features that help scientists understand the dynamics of the Earth's crust and the processes that shape our planet's surface.Rate this question:

The point underground where the earthquake's movement first take place is called the ________.
- A.
Crater
- B.
Epicenter
- C.
Fault
- D.
Focus
Correct Answer
D. FocusExplanation
The point underground where the earthquake's movement first takes place is called the focus. This is the exact location where the seismic waves originate and energy is released. It is usually deep within the Earth's crust and can be pinpointed by analyzing the arrival times of the waves at various seismograph stations. The focus is different from the epicenter, which is the point on the Earth's surface directly above the focus. The fault refers to the fracture or break in the Earth's crust where the movement occurs. A crater, on the other hand, is a depression or hollow in the ground usually caused by a volcanic eruption or meteorite impact.Rate this question:

Earth's plates move very slowly across Earth's surface on a thin layer of partly melted _____.
- A.
Core
- B.
Mantle
- C.
Volcanic ash
- D.
Crust
Correct Answer
B. MantleExplanation
The mantle is a layer of the Earth's interior that lies between the crust and the core. It is a partially melted layer of rock that is responsible for the movement of the Earth's tectonic plates. This movement, known as plate tectonics, occurs due to the convection currents in the mantle. These currents cause the plates to slowly move across the Earth's surface, leading to phenomena such as earthquakes, volcanic activity, and the formation of mountain ranges.Rate this question:

Scientists can _________ earthquakes by using seismographs, the Mercalli scale, and the Richter scale.
- A.
Measure
- B.
Predict
- C.
Weaken
- D.
Cause
Correct Answer
A. MeasureExplanation
Scientists can measure earthquakes by using seismographs, the Mercalli scale, and the Richter scale. Seismographs are instruments that detect and record the ground motion caused by seismic waves. The Mercalli scale is used to measure the intensity of an earthquake based on observed effects on people, buildings, and the natural environment. The Richter scale, on the other hand, measures the magnitude or energy released by an earthquake. By utilizing these tools and scales, scientists can accurately measure and analyze earthquakes, providing valuable data for further research and understanding of seismic activity.Rate this question:

- A.
Epicenter
- B.
River
- C.
Crater
- D.
Fault
Correct Answer
D. FaultExplanation
Christchurch experiences frequent earthquakes because there is a large fault running through the state. A fault is a fracture in the Earth's crust where rocks on either side have moved past each other. In this case, the movement along the fault causes the ground to shake, resulting in earthquakes.Rate this question:

Some volcanoes form new_______ as plates move apart and magma rises to the surface of the crust.
- A.
Volcanoes
- B.
Ocean floor
- C.
Earthquakes
- D.
Mantle
Correct Answer
B. Ocean floorExplanation
As plates move apart, magma rises to the surface of the crust, resulting in the formation of new volcanoes. This process occurs primarily in areas where tectonic plates diverge, such as along mid-ocean ridges. The magma that reaches the surface cools and solidifies, gradually building up the ocean floor. Therefore, the correct answer is "ocean floor."Rate this question:

Different kinds of _______ form different kinds of volcanic mountains.
- A.
Eruptions
- B.
Cinders
- C.
Slopes
- D.
Energy waves
Correct Answer
A. EruptionsExplanation
Different kinds of eruptions form different kinds of volcanic mountains. Volcanic mountains are formed when molten rock (magma) rises to the surface through volcanic eruptions. The type of eruption, whether it is explosive or effusive, determines the shape and characteristics of the volcanic mountain. Explosive eruptions, which involve the release of gas and ash, tend to create steep-sided and cone-shaped mountains. On the other hand, effusive eruptions, which involve the slow flow of lava, tend to create shield volcanoes with gentle slopes. Therefore, it is the eruptions themselves that directly influence the formation of different types of volcanic mountains.Rate this question:

How are Tsunamis caused?
- A.
Heavy rain
- B.
Earthquakes
- C.
Large tides
- D.
Ocean currents
Correct Answer
B. EarthquakesExplanation
Tsunamis are caused by earthquakes. When an earthquake occurs under the ocean, it can generate powerful seismic waves that travel through the water, causing the water to move in a series of waves. These waves then travel across the ocean, often growing in size and strength as they approach the coastline. When they reach shallow water, the waves can rise dramatically, forming a tsunami. Therefore, earthquakes are the primary cause of tsunamis.Rate this question:
-
- 19.
Once a tsunami hits land it loses energy and the waves stop.
- A.
True
- B.
False
Correct Answer
B. FalseExplanation
Tsunamis do not lose energy and stop when they hit land. In fact, they can continue to travel inland for several miles, causing destruction and damage along the way. Tsunamis are caused by underwater disturbances, such as earthquakes or volcanic eruptions, and their energy is carried by the waves. When these waves reach shallow water near the coast, they may slow down and increase in height, causing significant damage when they eventually hit land. Therefore, the statement that tsunamis lose energy and stop when they hit land is false.Rate this question:

Correct Answer
A. Harbour waveExplanation
Tsunami is a Japanese term that translates to "harbour wave" in English. This term refers to a series of ocean waves that are usually caused by underwater earthquakes or volcanic eruptions. These waves can travel across the ocean at high speeds and can cause significant damage and destruction when they reach coastal areas. The term "harbour wave" accurately describes the nature of a tsunami, as it emphasizes the massive size and potential impact of these waves on harbors and coastal regions.Rate this question:
