Card A
The movement of
sediments from one
place to another.
Card B
 Water
 Wind
 Ice
 Gravity
 Human
Factors
Card C
Small sediments are carried in the
water that rub against other
rocks.
Card D
Water pushing pebbles and
rocks across the bottom of a
river.
Card E
Water breaks down and absorbs
sediments and rocks.
Card F
The faster that water moves, the bigger and
heavier the sediments are that can be
carried by the water.

Card H
Deforestation allows water and wind
to move over the soil more easily,
resulting in the loss of topsoil.
Card I
Agriculture (crops & livestock grazing)
causes:
1. the removal of natural vegetation,
2. breaks soil into smaller particles,
3. loosens soil particles from the ground,
and
4. turning the area to a desert.
Result: water and wind can remove
the particles more easily.
Card J
Using pesticides (kills
insects) and fertilizers (adds
nutrients) can kill organisms
that help hold the soil
together.
Card K
Construction removes natural
vegetation, increases water runoff,
and increases surface wind speeds.
Card L
Industrial and residential wastes
can release acids into the soil that
break down the particles into
smaller pieces that are easier to
remove by wind and water.
Card M
Mining involves the removal of
soil and rocks from the ground
and mountain tops.
Card N
Erosion
Deposition is the dropping of
sediments at new location where
they accumulate together.
Deposition
Card O
When the agent of erosion
(wind, water, or ice) slows
down, it drops sediments that
it has been carrying.
