In a few words, describe what an earthquake is?
"MS-Ess2-3"
Learning objective:
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
Concepts:
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.
Which layer of Earth do most earthquakes occur in?
How fast can seismic waves travel through Earth's interior?
- Up to 13 km/s
- Up to 5 km/s
- Up to 40 km/s
What type of fault occurs when one block moves up and over another block during an earthquake?
- Reverse fault
- Normal fault
- Strike-slip fault
