Natural Disasters

Front

What is a natural disaster?

Back

A natural disaster is a major event caused by natural processes of the Earth that results in significant damage or destruction, such as earthquakes, volcanoes, floods, and hurricanes.

What is a volcano?

Back

A volcano is an opening in the Earth's surface where molten rock, ash, and gases can escape from below the Earth's crust.

Front

What is an earthquake?

Back

An earthquake is the shaking of the surface of the Earth resulting from a sudden release of energy in the Earth's lithosphere that creates seismic waves.

Front

What is a seismograph?

Back

A seismograph is a tool used to measure and record the intensity, duration, and direction of seismic waves produced by earthquakes.

Front

What are tectonic plates?

Back

Tectonic plates are large pieces of the Earth's lithosphere that move and interact with each other, causing geological activity like earthquakes and volcanic eruptions.

Front

What does it mean for a building to be earthquake-resistant?

Back

An earthquake-resistant building is designed to withstand seismic forces and minimize damage during an earthquake.

Front

What is the Richter scale?

Back

The Richter scale is a logarithmic scale used to measure the magnitude of earthquakes.

Front

What is the difference between a volcano and a mountain?

Back

A volcano is a mountain that has an opening through which lava, ash, and gases erupt, while a mountain is a large landform that rises prominently above its surroundings, usually formed by tectonic forces.

Front

What is the safest material to use for building near a volcano?

Back

Stone is considered the safest material to use for building near a volcano because it can withstand high temperatures.

Front

Why do earthquakes often occur along plate boundaries?

Back

Earthquakes often occur along plate boundaries because tectonic plates move and shift, causing stress that leads to seismic activity.
