In a few words, describe what an earthquake is?
Earthquakes are caused when plates in the Earth’s crust move and collide. Earthquakes can cause property damage, landslides, and tsunamis. Earthquakes are measured using a Richter Scale.
Earthquakes: What You Need to Know
Epicenter: the point on the earth's surface vertically above the focus of an earthquake Seismograph: a machine that records the shaking of the earth during an earthquake Richter Magnitude Scale: a numerical scale used to measure the magnitude of an earthquake
Earthquakes can cause the ground to ripple like a water wave. The energy released during an earthquake can travel as fast as 10 kilometers per second. Earthquakes can cause the ground to shake vertically, horizontally, or in a circular pattern.

What is the name of the scale used to measure earthquake magnitudes?
- Richter scale
- Fujita scale
- Beaufort scale
What is the difference between an earthquake's focus and epicenter?
- The focus is where the earthquake starts underground, while the epicenter is directly above it on the surface.
- The epicenter is where the earthquake starts underground, while the focus is directly above it on the surface.
- There isn't any difference between them.
