Geology and Weather Quiz

A region known for frequent volcanic eruptions and earthquakes.

• Pacific Ocean

• Pacific Ring of Fire

• Rift valleys

• Marianas Trench

Which of the following best describes the Pacific Ring of Fire?

• A circular ocean current in the Pacific Ocean

• A zone in the Pacific where tsunamis originate

• A fire belt in the Pacific where wildfires occur often

• A region around the Pacific Ocean known for the frequent earthquakes and volcanic activity

Why is the Pacific Ring of Fire prone to earthquakes and volcanic activity

• Because it is located in the middle of the Pacific Ocean

• Because it contains many tectonic plate boundaries

• Because it has the highest number of deep-sea trenches

• Because it is an area with high atmospheric pressure

How do normal faults differ from reverse faults?

• Normal faults occur due to compressional forces, while reverse faults occur due to tension

• Normal faults occur due to tension, while reverse faults occur due to compression

• Both normal and reverse faults are formed by the same forces

• Normal faults have no movement, while reverse faults always move

A researcher finds that a city experiences frequent seismic activities. What can be inferred about its geological setting?

• It is located near a tectonic plate boundary

• It is in the middle of a stable continent

• It is in an area with no fault lines

• It is far from any plate movement

What causes earthquakes?

• Movement along faults due to tectonic forces

• Heavy rainfall and flooding

• Strong winds and tornadoes

• Changes in atmospheric pressure

Evaluate the statement: “An earthquake of magnitude 6.0 is twice as powerful as one of magnitude 5.0.”(TRUE / FALSE)

• True

• False

• All the above

• Does not say

Why is the PHIVOLCS Faultfinder a useful tool for communities?

• It monitors rainfall and typhoons.

• It records historical weather data.

• It predicts the exact date of earthquakes.

• It provides data on the risk of earthquakes in specific areas.

During a tsunami warning, a local government uses mobile alerts to warn residents. If mobile networks are congested, what would be an effective alternative channel?

• Letter mail

• Email alerts

• Radio broadcast

• Increased social media posts

What is the main cause of a tsunami?

• Volcanic eruptions

• Underwater earthquakes

• Meteor impacts

• Heavy rainfall
