Erosion!

Changing Earth's Surface

100

This is the process in which sediments settle out of the wind or water carrying them.

Deposition

200

This is the natural force that moves rock and other sediments downhill.

Gravity

300

This is the process in which natural forces move sediments from one place to another.

Erosion

400

This is the most destructive of all types of mass movement.

Landslides

500

This type of mass movement is so slow you cannot see it happening; you can only see its affects (bent tree trunks and leaning fence posts).

Creep

Rivers

100

This is a landform formed when a meander is cut off from the rest of the river.

Oxbow lake

200

This term refers to any stream or river that flows into another stream or river.

Tributary

300

This is a depositional landform forming when rivers or streams flow into a non-flowing water body and drop their sediments.

Delta

400

This term refers to a bend or loop in a river.

Meander

500

This type of valley is formed as rivers flow quickly through steep, mountainous terrain.

V-shaped

Water

100

This term refers to all the remaining water that moves over Earth's surface.

Runoff

200

This is the greatest erosional factor (especially in CA).

Moving water

300

This is the water found underneath Earth's surface.

Groundwater

400

This is a flat, wide area of land that collects water during rainfall or flooding (the Yolo Bypass in Sacramento, for example).

Flood plain

500

Which area would collect a higher amount of runoff: a city or forest?

City

Glaciers

100

This type of glacier covers a very large amount of land (Antarctica).

Continental glacier

200

This term refers to the process in which glaciers move and pick up rocks and other sediments.

Plucking

300

This is the mixture of sediments that glaciers collect and deposit on Earth's surface.

Till

400

This type of valley is formed when a glacier erodes and flows slowly downhill.

U-shaped

500

This continent has glacier scratches proving that Pangea existed long ago.

What is Africa?

Waves

100

This energy source causes waves to form.

Wind

200

This process refers to water picking up sediments causing them to erode other sediments (can happen with sediments in wind, too).

Abrasion

300

This process refers to waves hitting shorelines at angles causing interesting types of deposition.

Longshore drift

400

True or False. A sea arch can form when all the rock around the sea arch is harder and resisted erosion.

False (the sea arch was harder rock and resisted erosion)

500

This depositional landform is created when longshore drift carries sediments out to form a finger-like projection.
