Wind erosion is more common in moist climates than in dry ones Wind erosion is more common in moist climates than in dry ones. True or False?

False

Wind erosion is the most common type of erosion in dry climates Wind erosion is the most common type of erosion in dry climates. True or False?

False

The area of the dune that faces away from the wind.

Leeward side

The process of deserts spreading into non-desert areas.

desertification

Desert pavement is formed by this erosion process.

deflation

Erosion by gravity is called this.

Mass wasting or mass movement

The main reason that erosion by gravity has increased in the last hundred years.

Human development of the land

The ____ the slope, the more likely mass movement will occur.

steeper

Slides that occur when large masses of soil slip down a curved surface.

slump

Daily Double!!

Evidence of this downslope movement of soil is the bending of tree trunks.

creep

Periods of global cooling that allow glaciers to build up and advance are called this.

Ice ages

The type of glacial erosion where rocks are lifted out of the ground after a glacier freezes to them.

plucking

Daily Half!!

A glacier needs to be this thick before it starts to flow.

20 - 30 meters

Glaciers are stationary when flow is _______ melting.

Equal to

Unsorted glacial deposits.

till

Valley glacier features are mostly (erosional / depositional).

erosional

This part of the glacier moves the fastest.

center

The type of glaciers that occurred here in Central Illinois.

continental

Two of these moraines come together to form a medial moraine.

lateral

Daily Half!!

Continental glaciers have mostly (erosional / depositional) features.

depositional

The % of an iceberg that is above the water.

10%

This erosion process is used by glaciers, wind, waves, and water.

abrasion

This type of mass wasting does more damage than any other.

creep

A layer of pebbles on the desert floor that is caused be deflation.

Desert pavement

Stones that are smoothed down due to excessive wind abrasion.

ventifacts

The shape of a valley glacier’s trough.

U

Type of moraine that forms underneath the glacier.

ground

The very fine silt that is created by glaciers and wind.

loess

Daily Double!!

These types of mass movement move as one cohesive mass.

slides

These types of mass movement move like a liquid (all mixed up).

flows

Topic: Glacier movement Final Jeopardy Topic: Glacier movement

The relationship between flow and melting that causes end moraines to form.

Flow = melting
