Question

Two students designed the experiment shown below to study stream erosion.

Faucet
Tray with sand
and gravel
Asteady stream of water flows from a faucet into a tray holding sand and gravel. The water forms a channel by eroding some of
he sand and gravel.
How can the students increase the amount of sand and gravel being eroded?
A by Increasing the water temperature
B by adding coarse gravel to the tray
by increasing the amount/speed of water flowing
D) by reducing the amount of flowing water

Answer 1

B. by increasing the amount/speed of water flowing

Step-by-step explanation:

The more water flowing and the faster it flows, the more the ground is eroded
