What is the point on the Earth's surface directly above the earthquake's focus called?

  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 are strongest.

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, cause the most damage to buildings and infrastructure due to their long duration and ability to induce strong ground shaking.

What is the Richter scale used to measure?

  1. Earthquake magnitude

  2. Earthquake intensity

  3. Seismic wave velocity

  4. Earthquake frequency


Correct Option: A
Explanation:

The Richter scale is used to measure the magnitude of an earthquake, which is a quantitative measure of the energy released during the event.

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

  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 materials. They are the first to arrive at a seismic station after an earthquake.

What is the process by which seismic waves are generated?

  1. Fault movement

  2. Volcanic eruptions

  3. Landslides

  4. Ocean currents


Correct Option: A
Explanation:

Seismic waves are primarily generated by the sudden movement of faults in the Earth's crust during an earthquake.

What is the term used to describe the shaking of the ground caused by seismic waves?

  1. Earthquake

  2. Magnitude

  3. Intensity

  4. Seismogram


Correct Option: C
Explanation:

Intensity refers to the shaking of the ground caused by seismic waves and is measured using the Modified Mercalli Intensity Scale.

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 a measure of the energy released by an earthquake and is determined using various methods, including the Richter scale.

Which type of seismic wave travels through the Earth's liquid outer 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 slower than P-waves. They are the second to arrive at a seismic station after an earthquake.

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

  1. Epicenter

  2. Hypocenter

  3. Magnitude

  4. Intensity


Correct Option: B
Explanation:

The hypocenter is the point within the Earth where an earthquake originates, while the epicenter is the point on the Earth's surface directly above it.

Which type of seismic wave causes the ground to move in a vertical direction?

  1. P-waves

  2. S-waves

  3. Surface waves

  4. Love waves


Correct Option: A
Explanation:

P-waves, also known as primary waves, cause the ground to move in a vertical direction and are the fastest seismic waves.

What is the term used to describe the recording of seismic waves?

  1. Seismogram

  2. Magnitude

  3. Intensity

  4. Epicenter


Correct Option: A
Explanation:

A seismogram is a graphical representation of the seismic waves recorded by a seismograph.

Which type of seismic wave travels along the Earth's surface?

  1. P-waves

  2. S-waves

  3. Surface waves

  4. Love waves


Correct Option: C
Explanation:

Surface waves travel along the Earth's surface and are the slowest seismic waves.

What is the term used to describe the frequency of seismic waves?

  1. Magnitude

  2. Intensity

  3. Frequency

  4. Period


Correct Option: C
Explanation:

Frequency refers to the number of oscillations of seismic waves per unit time.

Which type of seismic wave causes the ground to move in a horizontal direction?

  1. P-waves

  2. S-waves

  3. Surface waves

  4. Love waves


Correct Option: B
Explanation:

S-waves, also known as secondary waves, cause the ground to move in a horizontal direction and are slower than P-waves.

What is the term used to describe the amplitude of seismic waves?

  1. Magnitude

  2. Intensity

  3. Amplitude

  4. Period


Correct Option: C
Explanation:

Amplitude refers to the maximum displacement of seismic waves from their equilibrium position.
