8. Gravity causes mass movement.
9. Weathering and erosion produce and move
sediment, wearing down the land. The agents
of erosion also deposit sediment. Deposition
changes the shape of the land by building
it up.

1.
Moving water is the major agent of the erosion that has shaped Earth’s land
surface. It
also builds up the surface through deposition.
2.
A river erodes the land to form valleys, waterfalls, flood plains, meanders,
and oxbow
lakes.
3.
River deposition creates alluvial fans and deltas.
4.
Groundwater causes erosion through a process of chemical weathering.

A valley glacier is a long, narrow glacier that forms when snow and ice build up high in
a mountain valley. A continental glacier is a glacier that covers much of a continent or large
island.
2.
Glaciers form only in areas where more snow falls than melts. Snow builds up, and its
weight compacts the snow, forming ice that then begins to move downhill.
3.
When the depth of a glacier reaches about 30 to 40 meters, the glacier begins to
move downhill because of gravity. Continental glaciers flow in all directions.
4.
Glaciers erode the land by plucking and abrasion.
5.
When glaciers melt, they deposit sediment.

Lesson 4 Wave Erosion
Review and Reinforce Worksheet

1.
A sea stack forms when a sea arch collapses.
2.
A wave-cut cliff forms when waves erode the
base of a cliff so much that the rock above
collapses.
• 3.
A beach forms when waves deposit sediment
along a coast.
• 4.
A sea cave forms when waves erode a hollow
area in the rock along a coast.
• 5.
A spit forms as a result of deposition at
points where a headland or another obstacle
interrupts the longshore drift.
• 6.
Waves erode land by impact and by abrasion.
• 7.
Waves eventually even out a shoreline as their
energy becomes concentrated on headlands.

Lesson 5 Wind Erosion

1. Wind causes erosion mainly by deflation, the process by which
wind removes surface materials.
2. Wind picks up and moves through the air the smallest particles
of sediment such as clay and silt. Slightly heavier particles, such as
sand,
get skipped or bounced for a short distance. Larger particles slide or
roll along the ground.
3. When the wind meets an obstacle, sand the wind carries gets
deposited to form a sand dune.
4. The sediments in loess deposits are clay and silt, which are
finer than the sand grains in a sand dune.
