Brian's family has a compost pile at home. They put all the weeds they pull up from the garden in it as well as any vegetable waste they gather from the kitchen. If they keep it moist, all this vegetation will eventually turn into organic soil by the chemical process of decay. Since decay involves a variety of chemical reactions, how might temperature affect the rate at which the compost turns into soil? A) Temperatures near freezing would make it speed up.

B) It would happen faster at warmer air temperatures.

C) Changing temperatures would not affect the chemical reactions.

D) Warm summer air temperatures would make it slow down.
