Explain how the destruction of forests affects atmospheric levels of carbon.

Destruction of forests affects the levels of atmospheric carbon in two ways. With less trees pulling carbon dioxide from the atmosphere during the process of photosynthesis, atmospheric levels of carbon will increase. Also, when forests are destroyed the carbon that is stored in trees enters the carbon cycle, ultimately reentering the atmosphere.

before, trains worked using the steam engine. thus, it uses heat so it is crucial to apply heat balance. the steam engine absorbs energy during the stage of boiling water. so, this is the endothermic reaction. when the steam is used to work the piston, it has to release this energy through running the train. the excess energy is released as an exhaust to the chimney. this is the exothermic process because it releases energy to the surroundings.

the answer would be d : p
