Rock materials that eventually pile up along the sides of a glacier form terminal moraines.

a valley containing a glacier that enters ocean water

Which is the correct order of soil horizons starting at the ground surface?

Result of water chemically combining with decaying plant material

What is it called when water freezes in a crack and breaks the rock apart?

Carbon dioxide, oxygen, and water are often involved in chemical weathering.

Wider streams can carry larger rocks and boulders.

The formation of a delta is most closely related to the process of

Bowl shaped depression caused by wind erosion removing all the looses material

Which of these are in typical order of occurrence?

In a few limited places in the world, the originally created soils can still be found.

Which is the best condition for chemical weathering to occur?

An alluvial fan is like a river delta on land.

A layer of soil that forms from weathering bedrock and decaying plant material

What type of moraine is formed when till is dropped at the sides of a valley

A mountain peak eroded by glaciers on all sides

Which of these agents is always involved in mass wasting?

Which of the following is found in fertile soil?

When a depression forms in a ground moraine after glacial ice melts - what is it called?

What is the mass of weathered bedrock found at the base of a cliff called?

Winding ridge of sorted sediments deposited by meltwater stream flowing beneath a glacier

Counting varves is a reliable method of dating glacial lake sediments.

What type of moraine is formed when till is dropped at the front of a glacier

What type of erosion is caused by glaciers?

How is most of the sediment load carried in a stream?

Some glaciers can be found near the equator, but only in high mountains.

What is it called when rock and items are lifted by water freezing below the ground surface?

moraine formed when two glaciers merge to form one with the deposits in the middle

Water plays an important role in both mechanical and chemical weathering.

soil in rainy areas is typically

What is sudden glacier movement called?

What is it called when 2 or more glaciers merge at the base of a mountain?

A winter avalanche is not considered mass wasting because it involves only ice and snow.

What type of wind erosion forms ventifacts?

Long, streamlined hills with unsorted glacial till are called what?

Which mass wasting slips a short distance quickly?

What is formed when water chemically combines with carbonic dioxide?

What is the slow movement of the ground (that makes fences lean) called?

A rock glacier is basically a standard glacier that contains more rock than ice.

The soil in rainy climates tends to be alkaline (basic).

What forms Loess deposits?

Steep, hollow excavation made by glacial erosion in a mountain
