Earth Science Review

A volcano can directly change Earth’s surface by-

• adding heat to the atmosphere

• building up layers of hardened lava

• releasing water vapor into the air

• shooting out clouds of ash and smoke

Which of the following is one way an earthquake affects the Earth?

• Large cracks suddenly form in the ground.

• A big rock slowly moves across the land.

• Hills of sand form as the wind blows.

• A large amount of heat rises into the air.

A student gathered some rocks and soil to model the effects of a landslide. What is the best way to model how a landslide changes the Earth’s surface?

• Pack the materials into a closed container and shake them rapidly.

• Sift the materials through a strainer to separate the rocks and soil.

• Place the materials on a sloping surface and pour water on them.

• Spread the materials on a flat surface and blow on them with a straw.

Which would be an example of a rapid change to the Earth’s surface?

• A mountain forming due to volcanic eruptions

• A valley getting deeper as a river runs through it

• A plain forming cracks when hot weather makes it dry

• A hill rising as the wind piles up loose sand

The picture shows an island in the middle of the ocean that increased in size in only a few weeks. Which of the following most likely caused this rapid change in the island?

• Weathering of rocks

• Movement of waves

• Eruptions of a volcano

• Piling up of sand

Lava from a volcanic eruption can change the Earth’s surface by -

• forming new land

• making oceans boil

• carving deep valleys

• pushing aside hills

Which of the following best describes how earthquakes change the Earth’s surface? Earthquakes -

• throw rocks and ash into the air

• force lava through holes in the ground

• violently shift the surface of the earth

• cause clouds to form and rain to fall

The rock layers pictured here have split and shifted. What most likely caused this change?

• River

• Landslide

• Volcano

• Earthquake

Rocks, loose soil and sand rapidly sliding down a slope are a change to the surface of the earth known as a -

• Delta

• Volcano

• Landslide

• Glacier

Which events force melted rock from deep in the Earth toward the surface and build it up on the earth’s surface?

• Landslides

• Volcanic eruptions

• Earthquakes

• Mountain building
