Total questions: 17

Wind and rain can break down exposed rock.
True
False
What happens when sediment eroded by water, ice, and wind slows down or stops moving?
The sediment is deposited in a new location
The sediment continues to erode
The sediment mixes with other sediment to become rock
The sediment instantly turns into soil
Where do erosion and deposition occur in a river?
Deposition occurs where fast moving river water picks up soil and moves it downstream. Erosion occurs where a river current slows as it enters a larger body of water and drops the soil.
A river erodes land. There is no deposition.
A delta forms at the mouth of a river from depositon. There is no erosion.
Erosion occurs where fast moving river water picks up soild and moves it downstream. Deposition occurs where a river current slows as it enters a larger body of water and drops soil.
Chemical weathering happens fastest under which conditions?
low temperature
abundant water
glaciation
sparse plant growh
How is water a weathering agent?
It dissolves minerals in rocks
It grinds and polishes rock by moving particles against it
It grows on rocks to break the rock apart
It is not a weathering agent
_____________ determines the amount of runoff.
The amount of vegetation
The amount of rain
The slope of the land
all of the above
A __________ is a large mass of ice that forms on land and moves slowly.
Rock
Delta
Glacier
Sediment
Glaciers erode Earth's surface as they blow over it.
True
False
Which is a mixture of various sizes of sediment deposited by a glacier?
Till
Arete
Cirque
Which places are most likely to experience erosion from moving water?
Beaches and underground
streams and rivers
lakes and ponds
swimming pools
True or false: Flowing water deposits sediment as the water speeds up.
True
False
What is a meander?
a current that flows parallel to the shoreline
a broad, C-shaped curve in a stream
a large deposit of sediment that forms where a stream enters an ocean
Which type of wind is likely to cause the most erosion?
strong
gentle
moderate
What is the grinding away of rock or other surfaces as particles carried by wind, water, or ice scrape against them?
oxidation
abrasion
deposition
sandpaper
A pile of windblown sand is called
Loess
Dune
Sandbox
Desert
Mechanical Weathering
breaks apart rocks by physical processes
occurs when iron is exposed to oxygen and water
none of these
Chemical weathering
breaks apart rocks by physical processes
occurs when reactions dissolve or change minerals in rocks
none of these
