GREEN HOUSES
A green house is a building or complex where plants are grown. A greenhouse is a structural building with different types of covering materials, such as a glass or plastic
roof and frequently glass or plastic walls; it heats up because
incoming visible sunshine is absorbed inside the structure. Air warmed
by the heat from warmed interior surfaces is retained in the building by
the roof and wall; the air that is warmed near the ground is prevented
from rising indefinitely and flowing away.
