Earth's Surface

Which of the following most likely caused the change to the Earth's surface illustrated?

• landslide

• thunderstorm

• sinkhole

• earthquake

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

• A mountain's top cracking open 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.

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.

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

• river

• landslide

• earthquake

• volcano

Something that happens quickly to Earth's surface to make it different--

• Earth's surface

• Rapid change

• A river forming

• A mountain forming

Which of these most likely caused the rapid change to the Earth's surface illustrated here?

• landslide

• volcanic eruption

• mountain building

• sandstorm

A landslide is most likely to be caused by –

• strong winds

• breaking rocks

• heavy rains

• cold weather

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?

• Earthquake shaking the water

• Movement of waves

• Eruptions of a volcano

• Piling up of sand

Some events on Earth such as earthquakes, volcanoes, or tsunamis leave thin layers of clues from that catastrophe in the rock layers. These events that alter the Earth's surface are considered:

• a fast change to Earth's surface.

• a slow change to Earth's surface.

• no change to Earth's surface.
