When he blows into each of his two models, Tony sees that some soil comes out of each device. What should Tony do to better determine how plants reduce the effects of wind erosion on soil?

Question

A.
He should record the size of the soil particles before and after the activity.
B.
He should weigh each model before and after the activity.
C.
He should take the temperature of the soil in each model before and after the activity.
D.
He should add water to the model with the pieces of grass.

Answer 1

To better determine how plants reduce the effects of wind erosion on soil, the best option for Tony would be:

D. He should add water to the model with the pieces of grass.

By adding water, Tony can create a more realistic environment for the plants and observe how moisture interacts with the soil and plant roots in preventing erosion. This will help him understand the effect of vegetation on soil stability in windy conditions.
