Natural Disasters: Earth, Water, and Land

What is an earthquake?

• A phenomenon that causes floods and tsunamis.

• A type of volcanic eruption that creates lava flows.

• An earthquake is a sudden shaking of the ground caused by the movement of tectonic plates.

• A weather event that results in heavy rainfall.

What causes a flood?

• Strong winds

• Earthquakes

• Floods are caused by excessive rainfall, snowmelt, storm surges, or dam failures.

• High temperatures

Name one way to stay safe during an earthquake.

• Drop, cover, and hold on.

• Stand still and wait for it to pass.

• Run outside immediately without looking.

• Hide under a window or door frame.

What is a landslide?

What are some signs of a landslide?

• Heavy rainfall and flooding

• Presence of large boulders

• Stable ground with no movement

• Signs of a landslide include ground cracks, unusual soil movement, tilted trees, and increased water flow.

How do scientists measure earthquakes?

• Scientists measure earthquakes using seismometers.

• Through visual observation

• Using barometers

• By analyzing weather patterns

What is the Richter scale?

• A method for predicting future earthquakes.

• A logarithmic scale for measuring earthquake magnitude.

• A linear scale for measuring wind speed.

• A scale for measuring temperature.

Can floods happen in dry areas?

• Floods only occur in coastal regions.

• Yes, floods can happen in dry areas.

• Dry areas are immune to flooding.

• Floods can only happen in tropical climates.
