Sediments eroded from mountainsides and transported in streams are an example of the conservation of a) energy. b)matter. c)light. d)heat.

The example of conservation of matter are the sediments which are eroded from "mountainsides" and transported in streams.

Explanation:

When a mountainside is eroded down to form smaller sediments by natural forces like streams, rivers or winds, they are carried by the same forces to some other places and are eventually deposited. The action of carrying of the sediments by natural forces and depositing them elsewhere helps in the conservation of the sediment matter.

H=   2(area/a+b)h= 2(144/a+b)h= 2(144/18+18)h= 2(144/36)h= 2(4)h=8

The answer to this question is  c. pharmaceutical accumulation  reclaimed water refers to the water that being used again after it already  used for agricultural purposes.this type of water often contains pharmaceutical accumulation because of the chemical fertilizer that is used for the plants is absorbed into the water.
