Erosion!

Forces

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

The fiction or collision of these cause earthquakes and mountains to form.

Tectonic plates

Rivers

100

This is the most common water system.

dendritique

200

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

Tributary

300

This depositional landform is created when rivers or streams slow down 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. (letter)

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.

Moving water

300

This is the water found underneath Earth's surface.

Groundwater or aquifer

400

This is a flat, wide area of land that collects water during rainfall or flooding.

Flood plain

500

This area would collect a higher amount of runoff.

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. (letter)

U-shaped

500

This landform is formed when sea water fills in a U-shaped valley created by a glacier.

Fiord

Waves

100

This energy source causes waves to form.

Wind

200

This process refers to water (or wind) scraping away the Earth's surface. 

Abrasion

300

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

Longshore drift

400

This is a long high sea wave caused by an earthquake, submarine landslide, or other disturbance.

Tsunami

500

This is the sheer power of waves as they crash against a cliff.

Hydraulic action
