physical weathering
Plants and animals die and decay and produce acids that dissolve parts of rocks or make cracks and holes in the rock is _____________
chemical weathering
physical weathering
The amount of erosion a stream or river causes depends on what 3 things?
The amount of moving water, plants, and rain fall
Slope of the land, plants, and sediment
Slope of the land, plants, and the amount of moving water
Amount of rain fall, sediment, and plants
How does the height of the slope affect erosion?
As the slope increases, the amount of erosion increases
As the slope increases, the amount of erosion decreases
As the slope decreases, the amount of erosion increases
The slope must be the level as the erosion
How does the rate of flow affect erosion?
As the rate of flow increases, the amount of erosion increases
As the rate of flow increases, the amount of erosion decreases
As the rate of flow decreases, the amount of erosion increases
The rate of flow and the rate of erosion are not connected
