Chapter 4 science test

Which landform is found only where land meets an ocean?

• Plain

• Valley

• Coastline

• Mountain

How does weathering help form a sandy beach by the ocean?

• Melting glaciers deposit grains of sand

• Sandstorms deposit sand from nearby deserts

• Waves break rock into pieces, making grains of sand

• Chemicals in the waves dissolve large rocks in sand

A deep cave was discovered underground. Scientists found that the walls of the cave were made of limestone. The cave most likely formed through weathering by?

• Glacial ice

• Weak acid

• Heavy wind

• High waves

In the desert, wind carrying sand causes abrasion to rocks. What will happen to the rocks over time?

• They will crack

• They will blow away

• They will become bigger

• They will become smoother

In what way is a river valley like a canyon?

• Both are flat areas of land

• Both can be found near oceans

• Both are formed by moving water

• Both rise high above the land around them

How do weathering and erosion cause a landslide?

• Rock and soil slip downhill

• Moving ice deposits sediment

• Weak acid dissolves limestone

• Sandstorms blow sediment against rock

Last winter, Julie noticed a rock in her yard that had a small crack with water in it. After winter passed, she looked again and found that the crack had changed. What most likely happened to the crack during the winter?

• It got bigger because the water froze and expanded

• It got smaller after the water deposited sediment

• It got bigger because the water eroded the rock

• It got smaller when the water mixed with dust

A group of large boulders are in the middle of a grassy field. The boulders were once far away from the field. Which of these most likely moved the boulders to the grassy field?

• weathering and erosion by a river

• erosion and deposition by a glacier

• weathering and abrasion by a sinkhole

• abrasion and deposition by a sandstorm

What is weathering?

• dropping of sediment in a new place

• the breaking apart or wearing away of rock

• movement of sediment from one place to another

• the creation and destruction of landforms by weather

A sandstorm can move sand over great distances. Which most likely happens during a sandstorm?

• sediment is deposited in a new place

• rocks and soil slide down a hillside

• water freezes and splits rocks

• a cave forms underground
