What is an Earthquake?

An earthquake is an event that occurs when two tectonic plates, which are huge slabs of the Earth's crust, move against each other. These plates can grind past each other, pull apart, or collide, and when they do, they release a massive amount of energy that creates seismic waves. These waves cause the ground to shake. The strength of an earthquake is measured using the Richter Scale, which tells us how strong the shaking is.

Earthquakes can trigger landslides, tsunamis, and even volcanic eruptions, which can cause further destruction. Scientists study earthquakes to learn more about them and to find ways to protect people from their harmful effects.

What do scientists use to measure earthquakes?

Which statement is true about earthquakes?

• Earthquakes are not dangerous

• Earthquakes are caused when the earth's core gets extremely hot and shoots out molten rock.

• Earthquakes can sometimes cause other natural disasters like tsunamis, floods and volcanoes.

• Earthquakes only happened in the past. There are no more earthquakes in modern times.
