Question

1. Why is soil erosion relatively less in dense forests as compared to barren, open fields?

Answer 1

the roots of the trees keep the soil in place opposed to a barren landscape that has little to no plants to keep the soil in place

hope this helps (╹ڡ╹ )

Answer 2

Because the deep roots of big trees hold the soil and don't let it slip away simply by rain or wind.
