Weathering
What is weathering?
Weathering is the breaking or weathering down of rocks into smaller and smaller pieces.
What is Erosion?
Erosion is when wind, water, or ice move sediment from one place to another.
What is Deposition?
Deposition is when sediment is dropped in a new location either close or far away.
Which list below has the particles listed correctly from largest to smallest?
Gravel, Sand, Silt, and Clay
Weathering, erosion, and deposition change the Earth's surface over...
Many, many years.
This is how the sediment of the Earth's surface wears down, moves, and builds up
The cycle of weathering, erosion, and deposition
The process by which natural forces move weathered rock and soil from one place to another
Erosion
Sand dunes are landforms that may be observed at the base of a mountain range. The formation of these sand dunes is most likely the result of...
Deposition of sand by wind
When animals and plants die and decay in the soil?
Humus
What observable properties makes (Soil, Sand, and Clay) different from each other.
Color, size, and texture.
This type of mechanical weathering is caused by freezing and thawing
Ice Wedging
What can cause Erosion?
Wind, Water, Ice, and Gravity
This continuous cycle wears down and build up the Earth's surface
Weathering, erosion, and deposition
Several students investigate the characteristics of soil. The students observe samples of common soils. In one sample, they observe that water drains through the soil easily. When they rub the soil between their fingers, it feels rough and scratchy, and its particle feel hard. The soil the students observed is most likely...
Sand
This gradually weathers into smaller and smaller particles that begins to form.
