Weathering & Erosion

How would you describe the landscape made by alpine glaciers compared to the landscape made by continental glaciers?

• Alpine glaciers form U-Shaped Valleys, and continental glaciers form V- shaped valleys.

• Alpine glaciers form rugged landscapes, and continental glaciers form flat landscapes.

• Alpine glaciers form smooth landscapes, and continental glaciers form hilly landscapes.

• Alpine glaciers form flattened landscapes, and continental glaciers form uneven landscapes.

Sand dunes are formed where wind deposits sand it has been carrying. The following diagram shows a sand dune. The arrows show four different wind directions. Which arrow shows the direction in which the wind was blowing to form this sand dune?

• arrow Q

• arrow R

• arrow S

• arrow T

The continent of Antarctica is covered with an ice sheet. Which part of the Earth system includes the ice sheet?

• biosphere

• cryosphere

• atmosphere

• hydrosphere

The diagram shows how sediment is deposited as a fast flowing river reaches a flatter area of land. Which of the following does the diagram show?

• river delta

• flood plain

• alluvial fan

• oxbow lake

Storms can cause major changes to barrier islands by removing sand from the island. Which of the following would be expected to remove the most sand from a barrier island during a storm?

• waves depositing debris on the island

• currents moving sand along the island

• large waves crashing across the land

• strong winds blowing across the island

Which is a cause of physical weathering, but not chemical weathering?

• air

• wind

• acids

What happens to a rock when it is weathered?

• It is broken into smaller pieces.

• It is moved by wind, air, or water.

• It is built up as material is deposited.

• It is changed into another type of rock.

Zoe puts the two pebbles shown in a rock tumbler. The tumbler spins so the rocks bump against each other. When she takes the pebbles out, she discovers that pebble 1 had more abrasion than pebble 2.

• Pebble 2 is softer than Pebble 1.

• Pebble 2 is harder than pebble 1.

• Pebble 2 is less reactive than pebble 1.

• Pebble 2 is moer reactive than pebble 1.

Which statement correctly describes groundwater?

• any form of liquid water

• water that is not moving

• water on Earth's surface

• water below Earth's surface

While hiking in the mountains, Tanya observed a narrow and steep valley with a stream at the bottom of it. What most likely caused the valley to first form?

• an earthquake

• running water

• a rock landslide

• erosion by wind
