The three factors that relate to a stream's ability to erode material are ____________, ______________, and _______________.

• gradient, load, and discharge

• gradient, load, and distance

• load, discharge, and color

• gradient, discharge, and color

The load of a stream refers to

• the speed of the water

• the materials carried by the stream

• the steepness of the stream

• amount of energy in the movement of water

True or false? When a stream empties into a body of water, such as a lake or an ocean, its current slows and it deposits its load.

• true

• false

• When a stream empties into a body of water, such as a lake or an ocean, its current slows and it deposits its load.

• When a stream empties into a body of water, such as a lake or an ocean, its current increases and it deposits its load.
