EROSION AND ITS EFFECT Flashcards
is the removal of weathered
rocks and soil and their transfer to
another location.
Erosion
WHAT IS EROSION
is the removal of weathered
rocks and soil and their transfer to
another location.
is the
settling down of eroded materials in
a new location.
Deposition
Deposition
is the
settling down of eroded materials in
a new location.
WHeN DOES EROSION STOP?
when materials are deposited and
settled in the new location.
WHAT ARE THE NATURAL AGENTS OF EROSION?
Wind Erosion
Water Erosion
Avalanche
Gravity
are mounds of sand that are similar
to hills in shape.
DUNES
is common in dry places like deserts and the polar regions.
Wind erosion
T/F
In dry areas, sand,
soil, snow, or debris is not held together by moisture or roots of plants.
TRUE
is caused by the force of
moving water in rain, ocean waves, and river
current.
Water erosion
WHAT IS WATER EROSION?
Water erosion is caused by the force of moving water in rain, ocean waves, and river current.
T/F
Rain DOES NOT carriy loose particles that are
not being held together by the roots of plants.
How do trees/ plants prevent erosion?
The ROOTS F THE PLANT / TREES hols the soil
how does River current affect erosion?
River water transports sediments as it moves.
T/F
The rocks and soil carved out of the banks and bottom add to the sediments being carried off along the river.
TRUE
The deposition of river sediments near the mouth of the river creates
landforms such as
floodplains and river deltas.
What is Avalanche?
avalanche. It is a sudden downward flow of snow and ice from the mountains. Rocks and soil are carried with ice in an avalanche.
How does gravity cause erosion?
Gravity causes erosion by pulling rocks, soil, and other materials downward.
What is human-induced soil erosion?
Deforestation
Mining
Agricultural activities
Infrastructure
What is Mining?
Mining is the extraction of valuable minerals from soil and rocks.
What is Mining?
Mining is the extraction of valuable minerals from soil and rocks.
What are the agricultural activities cause erosion?
Repeated plowing
Excessive Chemical
Removal of trees
How does HUman infrastructure affect erosion?
Human infrastructure remove rocks and soil in certain locations to construct different structures.
