Step-by-step explanation:

A greenhouse is simply a building in which plants are grown. These buildings can be merely small structures, or they can also be quite large in size. The concept behind greenhouses dates back all the way to Roman times when the Emperor Tiberius demanded to eat an Armenian cucumber every day, for which his gardeners had to use a system similar to that in modern greenhouses to make sure he had one each day.

13th-century Italy was the site of the first modern greenhouses. Initially, greenhouses were more common on the grounds of the wealthy, but they soon also branched out to universities. The 19th century saw some of the largest greenhouses ever built, while the 20th century popularized the geodesic dome for use in many greenhouses.

How Does It Work? The greenhouse effect as it relates to actual greenhouses works in the following way. A greenhouse reduces the rate at which thermal energy flows out of its structure, and it does this by impeding heat that has been absorbed from leaving its confines through convection. The material for greenhouse construction is typically glass or plastic so that sunlight can pass through it. This sunlight is integral to the greenhouse becoming warm, since it heats up the ground inside the greenhouse. In turn, the warm ground then warms up the air in the greenhouse, which keeps on heating the plants inside since it is confined within the structure of the greenhouse.
