Most of the remaining energy is absorbed at the surface of Earth. Because the Earth's surface is colder than the Sun, it radiates at wavelengths that are much longer than the wavelengths that were absorbed.
Most of this thermal radiation is absorbed by the atmosphere and warms it.
The atmosphere also gains heat by sensible and latent heat fluxes from the surface. The atmosphere radiates energy both upwards and downwards; the part radiated downwards is absorbed by the surface of Earth.
This leads to a higher equilibrium temperature than if the atmosphere were absent. The solar radiation spectrum for direct light at both the top of Earth's atmosphere and at sea level An ideal thermally conductive blackbody at the same distance from the Sun as Earth would have a temperature of about 5.
The atmosphere near the surface is largely opaque to thermal radiation with important exceptions for "window" bandsand most heat loss from the surface is by sensible heat and latent heat transport. Radiative energy losses become increasingly important higher in the atmosphere, largely because of the decreasing concentration of water vapor, an important greenhouse gas.
It is more realistic to think of the greenhouse effect as applying to a "surface" in the mid- tropospherewhich is effectively coupled to the surface by a lapse rate. The simple picture also assumes a steady state, but in the real world, there are variations due to the diurnal cycle as well as the seasonal cycle and weather disturbances.
Solar heating only applies during daytime. During the night, the atmosphere cools somewhat, but not greatly, because its emissivity is low.
Diurnal temperature changes decrease with height in the atmosphere. Within the region where radiative effects are important, the description given by the idealized greenhouse model becomes realistic. It reradiates in all directions, both upwards and downwards; in equilibrium by definition the same amount as it has absorbed.
This results in more warmth below. Increasing the concentration of the gases increases the amount of absorption and reradiation, and thereby further warms the layers and ultimately the surface below. Greenhouse gases Main article: Greenhouse gas By their percentage contribution to the greenhouse effect on Earth the four major gases are: The absorption patterns of water vapor blue peaks and carbon dioxide pink peaks overlap in some wavelengths.
Carbon dioxide is not as strong a greenhouse gas as water vapor, but it absorbs energy in longer wavelengths 12—15 micrometers that water vapor does not, partially closing the "window" through which heat radiated by the surface would normally escape to space.Essay on greenhouse effect: free examples of essays, research and term papers.

Answer Key for Greenhouse Effect Assessment Questions 1. What is the major cause of the greenhouse effect? would there be a greenhouse effect? a) Yes, the greenhouse effect is caused by naturally occurring gases.
|Main Body. Protect your point of view||The Greenhouse Effect The greenhouse effect occurs when gases such as methane, carbon dioxide, nitrogen oxide and CFCs trap heat in the atmosphere by acting as a pane of glass in a car. The glass lets the sunlight in to make heat, but when the heat tries to get out the gases absorb the heat.|

Tips on Completing a Research About Global Warming There are certain points, which you should consider when you carry on the research on global warming:|
(correct) b) Yes, the greenhouse effect is caused by plants giving off gases. c) No, the greenhouse effect is caused by humans. The greenhouse effect happens when certain gases—known as greenhouse gases—collect in Earth’s iridis-photo-restoration.com gases include carbon dioxide (CO 2), methane, nitrous oxide (N 2 O), fluorinated gases, and ozone.
Greenhouse gases let the sun’s light shine onto the Earth’s surface, but they trap the heat that reflects back up into the atmosphere. Greenhouse effect happened because of human’s greediness and all countries are starting to find out the method to solve the issue of greenhouse in this twenty-first century.
