Solar radiation from the sun interacts with the Earth's atmosphere, warming the surface. Some of this energy is radiated back into space as infrared radiation. Greenhouse gases in the atmosphere trap some of this infrared radiation, causing a warming effect known as the greenhouse effect.

Is solar radiation absorbed at earth's surface and is reemitted as infrared radiation?
Yes, solar radiation is absorbed by the Earth's surface and is then reemitted as infrared radiation. This process is also known as the greenhouse effect, where certain gases in the atmosphere trap some of this infrared radiation, leading to warming of the planet.
What are the sources of energy that reach the troposphere?
The main sources of energy that reach the troposphere are solar radiation and infrared radiation emitted by the Earth's surface. Solar radiation heats the Earth's surface, which in turn emits thermal (infrared) radiation back into the atmosphere. This energy exchange drives atmospheric circulation and weather patterns within the troposphere.
The suns energy reaches the earth as what type of energy?
The sun's energy reaches the Earth as solar radiation in the form of electromagnetic waves, primarily in the form of visible light and infrared radiation.
What is the energy earth receives from the sun by infrared radiation and ultraviolet radiation?
The Earth receives approximately 50% of the Sun's energy in the form of infrared radiation, which is responsible for heating the planet's surface. The remaining 7% of solar energy comes in the form of ultraviolet radiation, which plays a crucial role in processes like photosynthesis and ozone formation in the atmosphere.
What is the energy received by earth from the sun in the form of radiation called?
The energy received by Earth from the sun in the form of radiation is called solar radiation. This includes visible light, ultraviolet light, and other forms of electromagnetic radiation emitted by the sun.
Is solar radiation absorbed at earth's surface and is reemitted as infrared radiation?
Yes, solar radiation is absorbed by the Earth's surface and is then reemitted as infrared radiation. This process is also known as the greenhouse effect, where certain gases in the atmosphere trap some of this infrared radiation, leading to warming of the planet.
Why is the atmosphere is heated cheifly by radition from Earth's surface rather than by direct solar radiation?
The atmosphere is heated chiefly by radiation from Earth's surface because the Earth's surface absorbs solar energy and emits it as infrared radiation. This infrared radiation is then trapped by greenhouse gases in the atmosphere, causing the atmosphere to be heated. Direct solar radiation contributes to heating the Earth's surface, which in turn warms the atmosphere through convection and radiation.
What type of radiation is trapped on the Earth's surface by the Greenhouse effect?
Infrared radiation is the type of radiation that gets trapped on Earth's surface by the greenhouse effect. This radiation is emitted by the Earth's surface in response to the incoming solar radiation and is absorbed and re-emitted by greenhouse gases in the atmosphere, leading to the warming of the planet.
What are the sources of energy that reach the troposphere?
The main sources of energy that reach the troposphere are solar radiation and infrared radiation emitted by the Earth's surface. Solar radiation heats the Earth's surface, which in turn emits thermal (infrared) radiation back into the atmosphere. This energy exchange drives atmospheric circulation and weather patterns within the troposphere.
Does the earth give off radiation?
Yes, the Earth does give off radiation in the form of heat. This radiation is primarily in the form of thermal infrared radiation emitted by the Earth's surface in response to solar energy absorbed during the day.
What happens to incoming solar radiation after it is reflected off the surface of the earth?
Incoming solar radiation that is reflected off the surface of the Earth can be absorbed by atmospheric gases, clouds, or particles in the air. Some of this radiation can be scattered or absorbed by the atmosphere and re-emitted as infrared radiation. This process helps regulate the Earth's temperature and maintain the energy balance of the planet.
What could decrease Earth's temperature?
Lower solar input & higher infrared radiation at night could decrease Earth's temperature.
What is the source of radiation for both the Earth's atmosphere and the greenhouse?
The primary source of radiation for both Earth's atmosphere and the greenhouse effect is the sun. Solar radiation warms the Earth's surface, which then emits infrared radiation. Some of this infrared radiation is absorbed by greenhouse gases in the atmosphere, trapping heat and warming the planet.
Most of the solar radiation absorbed by Earth's surface is later radiated back into space as which type of electromagnetic radiation?
Most of the solar radiation absorbed by Earth's surface is later radiated back into space as infrared radiation. This process helps to maintain Earth's energy balance and regulate its temperature.
What is the source of radiation for both the earth's atmosphere and the greenhouse effect?
The Sun is the primary source of radiation for both the Earth's atmosphere and the greenhouse effect. Solar radiation enters the atmosphere, warms the Earth's surface, and is re-radiated as infrared radiation. Greenhouse gases in the atmosphere trap some of this infrared radiation, leading to the greenhouse effect.
How the three types of thermal energy warm earths atmosphere?
Solar radiation—The sun emits energy in the form of electromagnetic radiation, which heats the Earth's atmosphere. Infrared radiation—The Earth's surface absorbs solar radiation and emits heat energy in the form of infrared radiation, which warms the atmosphere. Convection—The warmed air near the Earth's surface rises, carrying heat energy higher into the atmosphere and contributing to the overall warming.
What is the most significant source of radiation on Earth?
The most significant source of radiation on Earth is the sun, which emits solar radiation in the form of ultraviolet, visible, and infrared light. This solar radiation reaches the Earth's surface and is essential for sustaining life, but can also lead to risks such as sunburn and skin cancer if exposure is excessive.
