Natural Disasters

Front

What do you call a tool that measures the size of an earthquake?

Back

Seismograph: A device that records the intensity and duration of seismic waves caused by earthquakes.

Front

Why do so many volcanoes and earthquakes happen along plate boundaries?

Back

Plate Boundaries: Areas where tectonic plates meet, causing movement and shifting that lead to volcanic eruptions and earthquakes.

Front

What is the molten rock from a volcano called BEFORE it erupts at the Earth's surface?

Back

Magma: The hot, molten rock located beneath the Earth's surface before it erupts as lava.

Front

What causes tsunamis?

Back

Earthquakes: Sudden movements of the Earth's crust that can displace large amounts of water, leading to tsunamis.

Front

What do the lines on a map that show where earthquakes happen represent?

Back

Plate Boundaries: The lines indicate the edges of tectonic plates where earthquakes frequently occur.

Front

What is the term for the shaking of the ground during an earthquake?

Back

Seismic Activity: The vibrations and movements of the Earth's surface caused by the release of energy during an earthquake.

Front

What is lava?

Back

Lava: Molten rock that erupts from a volcano and flows on the Earth's surface.

Front

What is a tectonic plate?

Back

Tectonic Plate: Large pieces of the Earth's crust that move and interact with each other, causing geological activity.

Front

What natural disaster is caused by the sudden release of energy in the Earth's crust?

Back

Earthquake: A sudden shaking of the ground caused by the movement of tectonic plates.

Front

What is the term for a large ocean wave caused by underwater earthquakes?

Back

Tsunami: A series of large waves generated by the displacement of water due to seismic activity.
