Question

Explain greenhouse effect in detail.

Answer 1

GREENHOUSE EFFECT

The greenhouse effect is the process by which a planetary surface is warmed by radiation from its atmosphere to a temperature above what it would be in the absence of its atmosphere. If a planet's atmosphere contains greenhouse gases. The atmosphere radiates energy in all directions. The greenhouse gases include water vapor with three atoms (H2O), ozone (O3), carbon dioxide (CO2), and methane (CH4). Also, trace quantities of chloro-fluoro-carbons (CFC's) can have a disproportionately large effect.

Answer 2

Answer:

The greenhouse effect is a natural process that warms the Earth’s surface. When the Sun’s energy reaches the Earth’s atmosphere, some of it is reflected back to space and the rest is absorbed and re-radiated by greenhouse gases.

Greenhouse gases include water vapour, carbon dioxide, methane, nitrous oxide, ozone and some artificial chemicals such as chlorofluorocarbons (CFCs).

The absorbed energy warms the atmosphere and the surface of the Earth. This process maintains the Earth’s temperature at around 33 degrees Celsius warmer than it would otherwise be, allowing life on Earth to exist.
