Most of the electromagnetic radiation that comes to the earth from the sun is in the form of visible light. Light is made of waves of different frequencies. … Most of the solar radiation is absorbed by the atmosphere and much of what reaches the earth’s surface is radiated back into the atmosphere to become heat energy.
What role does radiation play in heating the atmosphere?
Air in the atmosphere acts as a fluid. The sun’s radiation strikes the ground, thus warming the rocks. As the rock’s temperature rises due to conduction, heat energy is released into the atmosphere, forming a bubble of air which is warmer than the surrounding air. This bubble of air rises into the atmosphere.
Why is radiation the fastest form of transfer of heat?
Answer: Radiation is fastest mode of Heat Transfer because it travel from emitting body to receiver body in the form of Electromagnetic waves … The Electromagnetic waves travels with the speed of light.. Example: we receive energy from sun in the form of radiations…
What is heating of the atmosphere?
Due to the chemical composition of the earth’s atmosphere, most of the infrared radiation emitted by the warm surface never reaches space. Instead the radiation is reflected or absorbed by compounds known as greenhouse gasses. When these compounds absorb the infrared radiation from the surface, the atmosphere heats up.
Why is convection The most important form of heat transfer in the atmosphere?
As the atmosphere does not readily mix conduction only really affect the part of the atmosphere in contact with the ground. … Convection is the transfer of heat by vertically moving air due to differences in buoyancy. Since air can rise (and fall) thousands of feet this is a much more effective form of heat transfer.
Is the slowest mode of transfer of heat?
The correct option is A) Radiation.
Radiation is the fastest mode of heat transfer while conduction is the slowest mode of heat transfer.
Is radiation a fastest mode of heat transfer?
Radiation occurs through vacuum or any other material medium. The heat is transferred at the speed of the electromagnetic wave in the medium, which is the speed of light in the medium. So radiation is the fastest among the three due to this reason.
