Describe an earthquake in just one word
Earthquakes are sudden shaking of the ground caused by movement of rocks deep beneath the surface of the earth. Earthquakes can cause damage to buildings, roads, and other structures. Earthquakes can also cause tsunamis, landslides, and other dangerous natural disasters.
Epicenter: The point on the Earth's surface directly above the focus of an earthquake. Richter Scale: A logarithmic scale used to measure the magnitude of an earthquake. Seismograph: An instrument used to measure and record the amount of ground movement caused by an earthquake.
The longest recorded earthquake lasted for almost 10 minutes! The most powerful earthquake ever recorded had the same amount of energy as 10,000 atomic bombs! Earthquakes can make the ground move up and down, side to side, or in a circular motion!
