Earth Science

What is weathering?

• a force that pulls pieces of rock downhill

• a process that builds up features on Earth's surface

• the picking up and moving of rock pieces from one place to another

• the breaking down of rock into smaller pieces at or near Earth's surface

Which is one way that earthquakes change landforms?

• They release ash and melted rock.

• They scrape away rocks on Earth's surface.

• They cause cracks to form in Earth's surface.

• They pick up weathered rock particles and move them.

When a glacier moves boulders over the land, this is an example of

• erosion

• eruption

• weathering

• ice wedging

What causes water to flow downhill?

• erosion

• gravity

• weathering

• the slope of the hill

Deposition is a process that

• breaks down rock

• builds mountains

• drops rock particles in new places

• moves rock particles to new places

Which landforms may form as a result of volcanic eruptions?

• cliffs

• deltas

• mountains

• floodplains

A glacier melts. Which landform will MOST LIKELY form where the glacier was?

• dune

• delta

• moraine

• mountain

How are earthquakes and volcanoes alike?

• They only occur on land.

• They are only destructive processes.

• They are only constructive processes.

• They are both constructive and destructive processes.

How are dams and levees alike?

• Both control floods.

• Both control weathering.

• Both are natural barriers.

• Both prevent coastal erosion.

How do storm drains help prevent flooding?

• They act like levees.

• They move storm water to dams.

• They block storm water from streets and houses.

• They allow storm water to flow into nearby waterways.
