What are the main factors that influence temperature?
There are primarily two factors that influence the temperature of the Earth, which are, the heating caused by sunlight during the day, and the cooling caused by the emission of infrared radiation into space at night. Greenhouse gases which intercept the infrared radiation are another significant factor.
The warm temperature observed in the stratosphere is primarily because of the absorption of ultraviolet radiation by ozone?
The source of the warmth of the stratosphere is the absorption of UV radiation by ozone, hence reduced ozone leads to cooling.
How do clouds increase or decrease global warming since they trap heat but they also reflect heat?
Clouds do reflect incoming sunlight back into space, as well as retain heat in the lower atmosphere. High clouds tend to have more of a warming effect because it is easier for solar radiation to pass through them, and also because the temperature at which they emit infrared radiation (heat) back to space is much less due to their cold temperature. Conversely, low clouds tend to be optically thick and reflect more solar radiation back to space, causing more of a cooling effect. They also emit more infrared radiation upward because they're emitting at a warmer temperature lower in the atmosphere, further adding to their cooling effect. However, scientists are not yet certain whether the net effect globally is cooling or warming.
What roles do radiation play in heating and cooling the earth?
Radiation transfers heat from one object to another. It does not require any particles unlike conduction and convection. Radiation travels in the form of electromagnetic waves.
What is the heat budget?
Is the balance between incoming short wave solar radiation (infra) and outgoing long wave solar radiation (TERESTRIAL) to avoid over cooling and overheating of the atmosphere.

Why are cooling pipes of a refrigerator are blackened?
Radiation is more effectively emitted by a black-body (absorbs all light) source, just as it is more effectively absorbed. If the effectiveness of emission and absorption were different, you'd violate the second law of thermodynamics. Short answer, black radiates heat away more effectively.
What condition favor the formation of fog by radiation cooling?
Cool, clear, and calm conditions favor the formation of fog by radiation cooling.
How is the thermal energy of the radiator transferred to the surrouding air?
A radiator had 2 major mode of heat tansfer. One is radiation where the energy is emitted in the form of infrared radiation to the surrounding. Other is convection since the hot surface cause air to expand and induce wind motion and cause rapid cooling.

What kind of current is above cooling cookies?
radiation
How does rock get broken down by radiation?
Through alternating heating and cooling.
What conditions favor the formation of fog by radiation?
Cool, clear, and calm conditions favor the formation of fog by radiation cooling.
What is the process of cooling water in refrigerator?
When every machine works, it does with heat emission. For this reason, the temperature of machines are going up. To prevent it from happening process of cooling water is needed.
What effect does dust and dirt have on earths radiation?
They tends to block incoming solar radiation, thereby cooling the surface. They don't really impact Earth's longwave radiation.
How do clouds reflect heat to earth?
Cloud cover prevents IR radiation and light from escaping to space, preventing cooling by radiation.
