What is the term used to describe the point on the Earth's surface directly above the earthquake's focus?

  1. Epicenter

  2. Hypocenter

  3. Magnitude

  4. Intensity


Correct Option: A
Explanation:

The epicenter is the point on the Earth's surface directly above the earthquake's focus, where the seismic waves reach the surface.

Which type of seismic wave causes the most damage to buildings and infrastructure?

  1. P-waves

  2. S-waves

  3. Surface waves

  4. Love waves


Correct Option: C
Explanation:

Surface waves, particularly Love waves and Rayleigh waves, cause the most damage to buildings and infrastructure due to their long duration and ability to shake the ground violently.

What is the Richter scale used to measure?

  1. Earthquake magnitude

  2. Earthquake intensity

  3. Seismic wave velocity

  4. Earthquake duration


Correct Option: A
Explanation:

The Richter scale is used to measure the magnitude of an earthquake, which is a logarithmic scale based on the amplitude of seismic waves recorded by seismographs.

What is the term used to describe the shaking of the ground caused by an earthquake?

  1. Magnitude

  2. Intensity

  3. Epicenter

  4. Hypocenter


Correct Option: B
Explanation:

Intensity is the term used to describe the shaking of the ground caused by an earthquake, which is measured using the Modified Mercalli Intensity Scale.

Which type of seismic wave travels through the Earth's solid crust?

  1. P-waves

  2. S-waves

  3. Surface waves

  4. Love waves


Correct Option: A
Explanation:

P-waves, also known as primary waves, are the fastest seismic waves and can travel through both solid and liquid parts of the Earth.

What is the term used to describe the boundary between two tectonic plates?

  1. Fault

  2. Epicenter

  3. Hypocenter

  4. Magnitude


Correct Option: A
Explanation:

A fault is the boundary between two tectonic plates, where earthquakes often occur due to the movement of these plates.

Which type of seismic wave travels through the Earth's liquid core?

  1. P-waves

  2. S-waves

  3. Surface waves

  4. Love waves


Correct Option: B
Explanation:

S-waves, also known as secondary waves, can only travel through solid materials and are not transmitted through the Earth's liquid core.

What is the term used to describe the sudden release of energy in the Earth's crust that causes an earthquake?

  1. Fault

  2. Epicenter

  3. Hypocenter

  4. Magnitude


Correct Option: C
Explanation:

The hypocenter is the point within the Earth's crust where the sudden release of energy occurs, causing an earthquake.

Which type of seismic wave is responsible for the rolling motion felt during an earthquake?

  1. P-waves

  2. S-waves

  3. Surface waves

  4. Love waves


Correct Option: C
Explanation:

Surface waves, particularly Rayleigh waves, are responsible for the rolling motion felt during an earthquake.

What is the term used to describe the energy released by an earthquake?

  1. Magnitude

  2. Intensity

  3. Epicenter

  4. Hypocenter


Correct Option: A
Explanation:

Magnitude is the term used to describe the energy released by an earthquake, which is measured using the Richter scale or the moment magnitude scale.

Which type of seismic wave is the first to arrive at a seismograph?

  1. P-waves

  2. S-waves

  3. Surface waves

  4. Love waves


Correct Option: A
Explanation:

P-waves, being the fastest seismic waves, are the first to arrive at a seismograph.

What is the term used to describe the study of seismic waves and earthquakes?

  1. Seismology

  2. Geology

  3. Meteorology

  4. Oceanography


Correct Option: A
Explanation:

Seismology is the study of seismic waves and earthquakes, including their causes, effects, and the structure of the Earth's interior.

Which type of seismic wave causes the most damage to underground structures?

  1. P-waves

  2. S-waves

  3. Surface waves

  4. Love waves


Correct Option: B
Explanation:

S-waves, due to their ability to cause shear deformation, are responsible for the most damage to underground structures.

What is the term used to describe the point within the Earth's crust where an earthquake originates?

  1. Fault

  2. Epicenter

  3. Hypocenter

  4. Magnitude


Correct Option: C
Explanation:

The hypocenter is the point within the Earth's crust where an earthquake originates.

Which type of seismic wave is responsible for the side-to-side shaking felt during an earthquake?

  1. P-waves

  2. S-waves

  3. Surface waves

  4. Love waves


Correct Option: B
Explanation:

S-waves, also known as shear waves, are responsible for the side-to-side shaking felt during an earthquake.
