Rhea lives in a house at the top of a sloped river bank. She has observed that a larger amount of soil from her lawn is sliding down the slope into the river. Her gardener suggested that she plant a row of shrubs along her yard to control the erosion. How will the shrubs help to control the erosion of the soil in Rhea's yard?

• The shrubs will block the river from flowing past her home.

• The plant roots prevent the soil from moving

• The shrubs will create a barrier to the wind

• The shrubs will make the bank of river a flatter surface
