100

This is the process of breaking rocks into smaller pieces by physical or chemical means.

What is Weathering?

100

This is the process of carrying away sediment.

What is Erosion?

100

This agent is responsible for mass movement and pulling materials downhill.

What is Gravity?

100

This landform is made of sediment left behind on flatter ground when mountain streams slow down.

What is Alluvial fan ?

100

A long ridge of sand that forms parallel to a shoreline and protects the mainland.

What is Barrier island (or barrier beach/island) — forms by deposition via longshore drift. ?

200

The laying down of sediment in a new location; a constructive force.

What is Deposition ?

200

The grinding away of rock by other rock particles carried by wind, water, or ice.

What is Abrasion?

200

This landform is created by wind when it deposits sand.

What is a Sand Dune?

200

The inside curve of a meander where sediment builds up is called the _____.

What is Point bar (inside curve of a meander). ?

200

 Formed by deposition where a river meets an ocean or lake; often triangular in shape.

What is delta?

300

The force that pulls rocks and soil down slopes, causing landslides.

What is Gravity ?

300

This is the process that involves sediment being dropped on riverbanks, deltas, or sandbars.

What is Deposition?

300

Plants actually prevent this process by holding soil in place with their roots.

What is Erosion?

300

A steep drop in a stream that can form when erosion undercuts the bedrock is called a _____.

What is Waterfall?

300

A block of rock left isolated from the cliff by wave erosion (taller stack of rock).

What is Sea stack?

400

A force that breaks down or destroys landforms (includes weathering and erosion)

What is Destructive force ?

400

This landform is created when deposition occurs at the mouth of a river, where sediment is dropped.

What is a Delta?

400

This chemical mixes with water to create carbonic acid, which causes chemical weathering and helps make caves.

What is Carbon Dioxide (CO2)?

400

A glacier deposits a mound or ridge of unsorted sediment called this.

What is Moraine (till pile; terminal or lateral moraine)?

400

These form when waves carve a hole in a cliff and then erode through to make a hole connecting two sides.

What are Sea arch (or arch)?

500

The process where rocks in waves hit the coastline and wear pieces off.

What is Abrasion by waves (rocks in waves hitting coastline). ?

500

This agent does the most shaping of the Earth, making it the major agent of erosion and weathering.

What is Water?

500

When this agent of erosion melts, it drops the sand and other sediment that it was carrying.

What is Ice? / What is a Glacier?

500

A bowl-shaped hollow at the head of a glacial valley, often where a glacier begins, is called a _____.

What is Cirque?

500

Narrow deposits of sand that extend from the coast and may shelter a bay; they form when longshore drift deposits sediment partway across a bay.

What is Sand spit (or spit)?
