• Density

• Multiplying

Multiple Choice

A rapid change is a change that occurs...

• Slowly

• Hot

• Cold

Landslides

Landslides are the movement of a mass of rock, debris, or earth down a slope.

Multiple Choice

What is the EFFECT of a landslide on hillsides where people live?
|

• sudden movement
• wildfires
• heavy rain
• damaged houses

Multiple Choice

Sudden movement of loose rock and soil down a steep slope is called a...

• avalanche
• landslide
• earthquake
• creep

Earthquakes

An earthquake is the shaking of the surface of the Earth resulting from a sudden release of energy.

Earthquakes occur most often along geologic faults, narrow zones where rock masses move in relation to one another.

Epicenter - center of the earthquake on the surface.

Multiple Choice

Which of the following most likely caused the changes in the location below?

• volcano

• weathering

• earthquake

• thunderstorm

Volcanos

a mountain or hill, typically conical, having a crater or vent through which lava, rock fragments, hot vapor, and gas are being or have been erupted from the earth's crust.

Volcanos (especially underwater) can result in the formation of new lands.

Multiple Choice

Molten rock that reaches the Earth's surface is...

• Smoke

• Lava

• ash

• magma

Multiple Choice

A _________ is an opening in the Earth's crust through which hot ash, gases, and molten rock escape.

• Volcano

• fault

• earthquake

• creep

Multiple Choice

Which rapid change on the surface of the Earth can form new land?

• Landslides

• Volcanos

• Earthquakes

• Weathering

Multiple Choice

Which of the following is a slow change on the Earth?

• Volcanic Eruption

• Weathering

• Landslides

• Earthquakes
