What causes earthquakes?

Back

Earthquakes are caused by the movement of tectonic plates beneath the Earth's surface, which can create stress and lead to sudden releases of energy.

Front

What is a tsunami?

Back

A tsunami is a series of large ocean waves typically caused by underwater earthquakes or volcanic eruptions.

Front

What is the Richter scale?

Back

The Richter scale is a logarithmic scale used to measure the magnitude of earthquakes, indicating the amount of energy released.

Front

What is the impact of natural disasters on human populations?

Back

Natural disasters can lead to displacement of communities, loss of life, destruction of property, and long-term economic instability.

Front

How do hurricanes form?

Back

Hurricanes form over warm ocean waters when moist air rises, creating low pressure that draws in more air, leading to powerful storms.

Front

What is the difference between a tornado and a hurricane?

Back

A tornado is a rapidly rotating column of air that extends from a thunderstorm to the ground, while a hurricane is a large storm system that forms over warm ocean waters.

Front

What is volcanic eruption?

Back

A volcanic eruption is the release of magma, gas, and ash from a volcano, which can cause destruction and alter landscapes.

Front

What is the term for the area where tectonic plates meet?

Back

The term is 'fault line', where stress builds up and can lead to earthquakes.
