the regions are, in order from surface to center: the surface, which is 10,000 degrees F. then there is the convection zone, then the radiation zone. Finally, we reach the core which is 27,000,000 degrees F.
Insolation is a measurement of the solar radiation received by a surface over a unit time. Polar regions have the lowest insolation.
A black surface absorbs the heat radiation and a white surface reflects the heat radiation
Tilt factor for beam radiation(Rb) is the the ratio of beam radiation on the surface under consideration and the beam radiation on a horizontal surface.
The poles are located at 90 degrees latitude. They are located at that part of the Earth's surface which is consistently the furthest from the the sun's heat and light radiation. The locations also receive radiation which has travelled the greatest distance within the atmosphere within which to be absorbed. These locations are, therefore, the coldest regions on the Earth's surface.
about 5% of radiation is lost before reaching Earth's surface
Yes, both. In some regions of the Sun, mainly one method of heat transport is used, in others, mainly the other.
The world's wetlands are believed to cover 7 to 9 million kilometers, (or about 4 to 5 miles), of the planet. That is roughly 4 to 6 percent of the earth's surface. Out of this, 56% of wetlands are found in tropical or subtropical regions.
the answer is radiation
90% of radiation reaching the surface of the earth is absorbed! and 10% is reflected into space.
southern regions
Heat rises from the surface of the earth in the form of infra-red radiation.
