an increase in the level of water in wells

Question 3

Which of the following statements is INCORRECT?

Accepted Answer

The time and location of major earthquake's intensity can be predicted several days before.

Answer

All earthquakes occur at plate boundaries.

Answer

Earthquakes can result in normal, reverse, and strike-slip faults.

Answer

P-waves nd S-waves are called seismic waves

Question 4

Which of the following best describes the epicenter of an earthquake?

Accepted Answer

The point on the Earth's surface directly above the focus.

Answer

The point within the Earth where the fault rupture begins.

Answer

The deepest point within the Earth where the seismic energy is released.

Answer

The area where the ground shaking is most intense.

Question 5

What is the primary factor that determines the magnitude of an earthquake?

Accepted Answer

The amount of energy released by the seismic event.

Answer

The type of fault responsible for the earthquake.

Answer

The depth of the earthquake's focus.

Answer

The distance from the epicenter to the affected area.

Question 6

How does earthquake intensity differ from earthquake magnitude?

Accepted Answer

Magnitude measures the energy released, while intensity measures the damage caused.

Answer

Magnitude measures the depth of the focus, while intensity measures the distance from the epicenter.

Answer

Magnitude measures the area affected, while intensity measures the frequency of aftershocks.

Answer

Magnitude measures the ground shaking, while intensity measures the duration of the earthquake.

Question 7

Which of the following is a potential effect of an earthquake on a community?

Accepted Answer

Damage to buildings, infrastructure, and loss of life.

Answer

Increased rainfall and flooding.

Answer

Displacement of tectonic plates.

Answer

Growth of vegetation and wildlife.

Question 8

What role does the focus of an earthquake play in determining its effects on the Earth's surface?

Accepted Answer

The shallower the focus, the greater the potential for tsunamis.

Answer

The focus has no direct impact on the effects of the earthquake.

Answer

The focus determines the direction of the seismic waves.

Answer

The deeper the focus, the more severe the ground shaking.

Question 9

How do earthquakes occurring underwater or along subduction zones contribute to the formation of tsunamis?

Accepted Answer

Underwater earthquakes release energy that generates seismic waves, which propagate through the water and create tsunami waves.

Answer

Subduction zone earthquakes cause the sudden uplift of the seafloor, displacing water and generating tsunami waves.

Answer

Underwater earthquakes trigger volcanic eruptions, leading to the formation of tsunamis.

Answer

Subduction zone earthquakes cause the release of toxic gases, resulting in the formation of tsunamis.

Question 10

What is the primary factor that determines the extent of devastation caused by tsunamis on shoreline communities?

Accepted Answer

The magnitude of the earthquake that triggered the tsunami.

Answer

The proximity of the shoreline community to the earthquake epicenter.

Answer

The frequency of tsunami events in the region.

Answer

The presence of advanced warning systems in the affected area.

Question 11

In what way do surface waves contribute to the destructive power of tsunami?

Accepted Answer

Surface waves interact with the seafloor, creating additional energy and increasing the height of tsunami waves.

Answer

Surface waves propagate quickly through the water, causing widespread flooding.

Answer

Surface waves carry debris and sediment, exacerbating the damage caused by the initial wave impact.

Answer

Surface waves generate strong winds that intensify the impact of tsunamis on shoreline communities.

Question 12

How can coastal communities mitigate the impact of tsunamis on their shoreline infrastructure?

Accepted Answer

By constructing seawalls and levees to absorb the energy of tsunami waves.

Answer

By conducting regular drills and exercises to test emergency response plans.

Answer

By encouraging residents to build homes closer to the coastline for easier evacuation during tsunamis.

Answer

By relying solely on early warning systems to evacuate residents before the arrival of a tsunami.

Question 13

Which of the following statements best describes the purpose of intensity scales in assessing earthquake effects?

Accepted Answer

Intensity scales evaluate the effects of an earthquake on people, structures, and the environment.

Answer

Intensity scales determine the duration of shaking during an earthquake.

Answer

Intensity scales quantify the energy released by an earthquake.

Answer

Intensity scales measure the depth of an earthquake's epicenter.

Question 14

How does the Modified Mercalli Scale differ from the Richter Scale?

Accepted Answer

The Modified Mercalli Scale measures earthquake effects, while the Richter Scale measures ground shaking.

Answer

The Modified Mercalli Scale measures earthquake magnitude, while the Richter Scale measures earthquake intensity.

Answer

The Modified Mercalli Scale measures earthquake depth, while the Richter Scale measures earthquake duration.

Answer

The Modified Mercalli Scale measures earthquake frequency, while the Richter Scale measures earthquake location.

Question 15

During an earthquake, what is the most appropriate action to take if you are indoors?

Accepted Answer

Stay inside and hide under a sturdy piece of furniture.

Answer

Stand in a doorway to prevent door collapse.

Answer

Turn off all utilities and evacuate the building.

Answer

Run outside and seek open space immediately.

Question 16

What is the primary goal of tsunami evacuation procedures?

Accepted Answer

To seek high ground or move inland to avoid tsunami waves.

Answer

To drive to the coast and observe the tsunami.

Answer

To gather belongings and secure valuables.

Answer

To stay inside buildings and wait for rescue.

Question 17

Which of the following measures an earthquake's intensity based on the observed effects on people and structures?

Accepted Answer

Modified Mercalli Scale

Answer

Centigrade Scale

Answer

Moment Magnitude Scale

Answer

Richter Scale

Question 18

Where are earthquakes most likely to take place?

Accepted Answer

near a fault zone

Answer

along the core-mantle interface

Answer

near the Earths' equator

Answer

near the area of the earth where the composition is uniform

Question 19

Which of the following items should be included in an earthquake preparedness kit?

Accepted Answer

All of the above.

Answer

A battery-operated radio and extra batteries.

Answer

Bottled water and non-perishable food items.

Answer

Matches and candles for lighting.

Question 20

Which of the following cannot be provided by a seismograph?
