What are the two types of earthquakes?

• tectonic and plate

• volcanic and epicenter

• magnitude and intensity

• volcanic and tectonic

Refers to the amount of energy released by an earthquake from its focus.

• intensity

• fault

• magnitude

• epicenter

The scale used to measure magnitude.

• seismograph

• richter scale

• intensity scale

• mercalli scale

Refers to the effects of the earthquake as shown in the destruction of buildings, crops, and the number of casualties.

• magnitude

• intensity

• fault

• epicenter

An earthquake is referred to as _____________ if a sudden displacement of the earth's crust occurs along a fault, or break in the rocks.

• tectonic earthquake

• volcanic earthquake

• fault earthquake

• epicenter earthquake

Intensity scale was developed by_______

• Charles Francis Richter

• Giuseppe Mercalli

• Aristotle

• Albert Einstein

The earth's crust shakes and the strength of movement depends on the distance of an area from the focus and epicenter of the earthquake.

• landslide

• land slippage

• land rupture

• ground tremors

Hillsides and high cliffs become unstable as the strong shocks of an earthquake cause _______.

• ground tremors

• landslides

• land rupture

• land slippage

The shock near the epicenter can cause land surfaces to break open.

• ground tremor

• lanslides

• land rupture

• land slippage
