GRADE 6 Earthquake

This refers to the shaking of the surface of the Earth.

• volcanism

• earthquake

• landslide

• erosion

This type of shaking occurs when plates bump or scrape as they slide along each other.

• mechanical earthquake

• tectonic earthquake

• volcanic earthquake

• oceanic erthquake

The pressure that has built up in between the plates is released in the form of energy waves also known as __________________.

• seismic waves

• heat waves

• mechanical waves

• systematic waves

The point that is directly above the focus of the earthquake is called the ___________________.

• hypocenter

• radius

• central point

• epicenter

This refers to the amount of energy released by an earthquake.

• intensity

• capacity

• magnitude

• energy waves

A device used to measure the amount of energy produced by an earthquake is called _______________.

• seismograph

• Rossi Scale

• anemometer

• Richter Scale

This refers to the strength of an earthquake based on its effects on the Earth's surface, structures, and humans.

• casualties

• intensity

• magnitude

• energy waves

These are downward movements of rocks or soil on slopes.

• landslides

• liquefaction

• tsunamis

• ground rupture

This is the process in which earthquakes turn loose, water-saturated soil into a liquid. This may sink houses and buildings a few inches or by several feet.

• landslides

• liquefaction

• tsunamis

• ground rupture

These are the rising and falling of the water caused by an earthquake on the oceanic plate.

• landslides

• liquefaction

• tsunamis

• ground rupture
