Question

This was once a forested hillside. The county where this hill is located decided to widen the roads in the area and all of the trees and shrubs were cut down. All that was left was large boulders, gravel, and a thin layer of soil. Two years later, this was the scene. If left undisturbed, what can we expect to see in this space over the next several years? Choose ALL the answers that apply.

Responses
A The lichen and loss growing now will help enrich the thin soil. The lichen and loss growing now will help enrich the thin soil.
B First grasses and low growing plants will start to grow. First grasses and low growing plants will start to grow.
C The soil on the hill will erode and be washed into the new road. The soil on the hill will erode and be washed into the new road.
D In a few years, large trees will be established on the hillside. In a few years, large trees will be established on the hillside.
E Eventually, woody shrubs will begin to establish.

Answer 1

it’s b and d

Step-by-step explanation:

Answer 2

After the trees and shrubs were cut down and the hillside was left with large boulders, gravel, and a thin layer of soil, we can expect the following to occur:

A. The lichen and moss growing now will help enrich the thin soil. As lichen and moss grow, they can help to break down the rocks and boulders on the hillside, creating small pockets of soil in which other plants can grow.

B. First grasses and low growing plants will start to grow. These plants are well-adapted to grow in rocky, gravelly soils and can help to stabilize the hillside, preventing erosion.

D. In a few years, large trees may begin to establish on the hillside. Trees have deep roots that can help to anchor the soil in place and prevent erosion.

E. Eventually, woody shrubs may begin to establish on the hillside. Shrubs have shallower roots than trees and are well-suited to grow in rocky, gravelly soils. As shrubs become established on the hillside, they can help to provide additional stability and prevent erosion.

C. The soil on the hill may erode and be washed into the new road. If the soil on the hillside is not stabilized, it may be prone to erosion, which can wash away the thin layer of soil and expose the underlying rocks and boulders. This can lead to the erosion of the hillside and the washing of soil into the road below.
