Quiz On Earthquakes Questions
Questions and Answers
- 1.
Earthquakes occur when energy that has been built up between tectonic plate margins is released.
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
Earthquakes occur when there is a release of energy that has been accumulated between tectonic plate margins. This energy buildup is a result of the constant movement and interaction of the Earth's tectonic plates. When the stress and pressure become too great, the plates slip or break, causing seismic waves to be generated and resulting in an earthquake. Therefore, the statement is true as it accurately explains the cause of earthquakes.Rate this question:

The place at which the shock waves first reach the earth’s surface is known as the.....
Correct Answer
EpicentreExplanation
The epicentre is the point on the Earth's surface directly above the focus of an earthquake, where the shock waves first reach the surface. It is the location where the seismic energy is released and the strongest shaking is felt.Rate this question:

What components are used to measure earthquakes today?
- A.
Seismograph
- B.
Climograph
- C.
Magnitude scale
- D.
Richter scale
Correct Answer(s)
A. SeismograpH
C. Magnitude scaleExplanation
Seismographs and magnitude scales are components used to measure earthquakes today. A seismograph is an instrument that detects and records the vibrations caused by seismic waves, providing valuable data on the intensity and duration of an earthquake. The magnitude scale, such as the Richter scale, quantifies the energy released by an earthquake at its source. By combining the measurements from seismographs and magnitude scales, scientists can accurately assess the size and impact of earthquakes.Rate this question:

What is a tsunami?
- A.
A big tidal wave
- B.
Ocean waves caused by underwater movement
- C.
A mountain or hill that can erupt with lava
Correct Answer
B. Ocean waves caused by underwater movementExplanation
A tsunami is a series of ocean waves that are caused by underwater movement, such as an earthquake, volcanic eruption, or landslide. These waves can travel across the ocean at high speeds and can cause significant destruction when they reach the coastline. Unlike regular ocean waves, tsunamis have much longer wavelengths and can travel across entire ocean basins. They can be extremely powerful and can cause widespread flooding, damage to coastal infrastructure, and loss of life.Rate this question:

Effects of an earthquake can be divided into 3 categories.....
Correct Answer
Primary effects,secondary, effects tertiary and effects. - 7.
What are primary effects?
- A.
Effects directly related to the earthquake
- B.
Short term effects of the earthquake
- C.
long term effects of the earthquakes
- D.
Effects that do not matter
Correct Answer
A. Effects directly related to the earthquakeExplanation
Primary effects refer to the immediate and direct consequences of an earthquake. These effects are directly caused by the seismic activity and include shaking of the ground, ground rupture, landslides, and tsunamis. They can result in casualties, injuries, and structural damage to buildings and infrastructure. Primary effects are distinct from secondary effects, which are the indirect consequences that occur as a result of the primary effects, such as fires, aftershocks, and economic impacts.Rate this question:

Short term effects of an earthquake are called...
Correct Answer
secondary effectsExplanation
Short term effects of an earthquake are referred to as secondary effects. These effects are the immediate consequences of the seismic activity, such as aftershocks, landslides, tsunamis, and fires. Unlike primary effects, which include ground shaking and building collapse, secondary effects occur as a result of the primary effects and can cause further damage and loss of life. These secondary effects often intensify the impact of an earthquake and pose additional risks and challenges for affected communities in the aftermath of a seismic event.Rate this question:
- 9.
Tertiary effects are direct effects of an earthquake.
- A.
True
- B.
False
Correct Answer
B. FalseExplanation
Tertiary effects are not direct effects of an earthquake. Tertiary effects refer to the indirect consequences that occur as a result of the primary and secondary effects of an earthquake. These effects can include things like landslides, fires, and tsunamis, which are not directly caused by the seismic activity but are triggered by it. Therefore, the statement that tertiary effects are direct effects of an earthquake is false.Rate this question:

Where do less destructive earthquakes occur?
- A.
Where it is winter on the globe
- B.
In the centre of the plate
- C.
Where there is no plate covering the area
- D.
Away from plate margins
Correct Answer
D. Away from plate marginsExplanation
Less destructive earthquakes occur away from plate margins. Plate margins are the boundaries where tectonic plates interact and collide, resulting in more intense seismic activity. In contrast, areas away from plate margins experience fewer and less powerful earthquakes. This is because the movement and pressure between tectonic plates are reduced in these regions, leading to less destructive seismic events.Rate this question:
