400
As partical size increases stream velocity needs to ______
What is increase
400
If a river is flowing at a velocity of .5 cm/s, what is the largest size particle it can carry
What is sand
400
Compared to an area of Earth’s surface with gentle slopes, an area with steeper slopes most likely has ______ infiltration and ________ runoff
What is less and more
400
Which climate will chemical weathering be most rapid?
What is hot and humid
400
In cold and alpine environments water enters cracks in rocks during the daytime. At night, as temperatures fall below freezing, and the water freezes and expands. This exerts a pressure on the cracks and they can, over many years, increase in size. This process is called.
