Which of the following is not released by trees into the atmosphere?

a.
oxygen
b.
water vapor
c.
ozone
d.
none of the above

The correct answer is Ozone.

Trees does not release Ozone into the atmosphere.

Trees release oxygen through the process of photosynthesis whereby the oxygen is being breathed inside by human beings. Trees release water vapor through process of respiration.

Ozone is a gas which has pungent smell. Ozone is well known as allotrope of oxygen and it is not stable as diatomic allotrope.

Ozone is being formed by action of ultraviolet light which is from dioxygen.

increase soil erosion                                             reduce soil erosion

cattle grazing                                                         hydroseeding

deforestation                                                         contour plowing

                                                                                planting vegetation

plant roots basically hold the top soil

together and stop soil erosion because

in such situation top soil is not removed

during flood but cattle grazing causes

soil erosion because cattle consume the

grasses and herbs and top soil is exposed.

same situation occurs because of

deforestation, the trees and plants are cut

down to expose top soil which causes soil

erosion
