Large shrubs and trees are often planted near rivers to help prevent flooding. The deep, highly-absorbent roots of these shrubs
and trees help soak up heavy rains before they begin to flood the land. Because they reach high above the ground and their branches
and leaves spread outward, trees can also reduce the amount of rainfall that reaches the ground by up to 45%. In the event of a
flood, what additional benefit might these shrubs and trees provide?
They store and hold excess water to prepare for dry seasons:
B)
They prevent flood waters from entering and polluting the rivers.
O
They help to slow down the flow of water, reducing damaging impacts.
D)
They absorb harmful pollutants and stop debris from entering the river.
Convection occurs when particles with a lot of heat energy in a liquid or gas move and take the place of particles with less heat energy. Heat energy is transferred from hot places to cooler places by convection. Liquids and gases expand when they are heated. ... The denser cold liquid or gas falls into the warm areas.
