What Is the Greenhouse Effect?

The earth, unlike all other planets, has a stable temperature that supports the existence of human and other living organisms. The earth enjoys these benefits because of its atmosphere. The atmosphere is a layer of gas that covers the earth and protects it from the sun. Over the years, human activities have adversely affected the atmosphere leading to what climate scientists call global warming. In this informative piece, you would learn about the greenhouse effects and how it leads to global warming.

Greenhouse Effect

Every day, the earth receives a high amount of radiation from the sun and neighboring planets. Radiation from the sun hits the earth in various form like visible light, infrared (IR), ultraviolet rays (UV) and so many other forms of radiation that are invisible to man.

All these radiations have their effect on the atmosphere. However, they do not hit the earth due to the protection that is offered by the atmosphere. The radiations that should hit the earth is quickly reflected into space by reflective surfaces that are largely present on the earth. However, a good percentage of these radiations are absorbed into the earth by the land, water bodies, and the atmosphere. These radiations go on to cause thermal radiation or what is known as heat. The thermal radiation, in turn, is passed into the atmosphere and moves into space in a continuous cycle.

This cycle leads to what is called the atmospheric equilibrium. Atmospheric equilibrium is responsible for the balanced temperature we enjoy on earth. The cycle balances off the radiation that enters and leaves the earth, making it possible for living organisms to exist comfortably. Without the atmospheric equilibrium, the earth would either be as cold as the moon or as hot as the other planets that are close to the sun.

How It Works

The movement of radiation to and from the earth is known as the greenhouse effect. The greenhouse effect is coined from the same principles guiding the operations of the greenhouse. The greenhouse uses the principles of trapping radiations inside the glass covering. These weak radiations get into the house through the glass but are unable to leave. Thus, they are used to provide warmth for the plants inside the house. The principle is employed in growing plants through all seasons without affecting their cycle of production.

However, unlike the operations of the greenhouse which is human-made, the greenhouse effect is a natural process. The process ensures that the surface of the earth is warm enough for the existence of life. The radiations are also absorbed by special atmospheric gases known as the greenhouse gases. The greenhouse gases are carbon dioxide, ozone, methane, water vapor, nitrous oxide and other artificial gases from the chlorofluorocarbon chemicals. The weaker radiations are absorbed to keep the earth warm while the strong radiations are reflected into space. This is all you need to know about the greenhouse effect.
