Question

In the experiment described, what is the expected difference in the amount of eroded soil collected between the tray with sod and the tray with just soil?

A) More eroded soil in the sod tray
B) More eroded soil in the soil-only tray
C) No difference
D) Cannot be determined from the information provided

Answer 1

The soil-only tray is expected to have more eroded soil compared to the tray with sod, as the vegetation in the sod helps prevent soil erosion.

Step-by-step explanation:

In the experiment described, there would be more eroded soil in the soil-only tray than in the tray with sod. This is because the sod (which includes grass and its roots) helps to anchor the soil, reducing erosion. On the other hand, soil without any plant cover is more susceptible to erosion, whether by wind or water runoff. It's a well-established fact in environmental science that vegetation cover plays a key role in preventing soil erosion.
