What is 20 percent of the radiation from the sun?
Twenty percent of the radiation from the sun refers to the portion of solar energy that reaches the Earth's atmosphere. This radiation includes visible light, ultraviolet light, and infrared radiation, which are essential for life on Earth. The remaining 80 percent is absorbed or scattered by the atmosphere before it reaches the surface. Ultimately, the radiation that reaches the Earth's surface is crucial for climate, weather patterns, and supporting ecosystems.
Why is the sun heated unevenly?
The sun is heated unevenly due to the dynamic nature of its interior. Energy generated in the core through nuclear fusion is carried to the surface by processes like convection and radiation. Variations in temperature, pressure, and magnetic fields play a role in creating the uneven distribution of heat across the sun's surface.
What is the function the atmosphere?
to trap heat from the sun to shield the planet from harmful radiation and to disintigrate space debris before it reaches the surface
Do clouds reflect sun's radiation?
Yes, clouds can reflect incoming solar radiation due to their high albedo, which is the measure of how much sunlight is reflected off a surface. This reflection can have a cooling effect on the Earth's surface by reducing the amount of solar radiation that reaches it.
How does the sun's energy travel?
The sun's energy travels through space in the form of electromagnetic radiation, including visible light, ultraviolet light, and infrared radiation. This energy is emitted from the sun's surface in all directions and reaches Earth in about 8 minutes.
Why are people unevenly distributed on earth surface?
why are people unevenly distributed on the earths surface
What happens to the shortwave radiation that reaches Earth's surface and is not reflected?
The shortwave radiation that reaches Earth's surface and is not reflected is absorbed by the surface, warming it up.
What is the term for solar radiation that reaches the earth's surface?
The solar radiation that reaches the earths surface from the sun is called INSOLATION
What happens to most solar radiation when it reaches the surface of Earth what happens?
Most of the solar radiation is absorbed when it reaches the surface of the earth. Some of the solar radiation is also absorbed in the atmosphere.
How does solar radiation reach the surface of the earth?
Solar radiation reaches the surface of the Earth through the process of electromagnetic radiation emitted by the Sun. This radiation travels through space and reaches Earth's atmosphere, where it penetrates and warms the surface of the planet. The atmosphere helps block harmful radiation while allowing sunlight to reach the surface.
What happens when radiation reaches earth's surface?
When radiation reaches Earth's surface, it can be absorbed, reflected, or scattered. The amount of radiation that is absorbed can contribute to heating of the surface and atmosphere. This process is fundamental for maintaining Earth's energy balance and climate.
How thermal energy reaches Earth's surface?
Thermal energy reaches Earth's surface primarily through radiation from the sun. The sun emits electromagnetic radiation that travels through space and warms the Earth's surface upon contact. This process is known as solar radiation.
Why doesn't all radiation directed at earth reaches the surface?
It is absorbed by the atmosphere
What percentage of the suns radiation that reaches the earths atmosphere is absorbed by earths surface?
About 50% of the sun's radiation that reaches Earth's atmosphere is absorbed by the Earth's surface. The remaining energy is either reflected back to space or absorbed by the atmosphere.
What is 20 percent of the radiation from the sun?
Twenty percent of the radiation from the sun refers to the portion of solar energy that reaches the Earth's atmosphere. This radiation includes visible light, ultraviolet light, and infrared radiation, which are essential for life on Earth. The remaining 80 percent is absorbed or scattered by the atmosphere before it reaches the surface. Ultimately, the radiation that reaches the Earth's surface is crucial for climate, weather patterns, and supporting ecosystems.
How is heat transfered fron the sun to eatrh?
Heat from the sun is transferred to Earth through electromagnetic radiation, mainly in the form of visible light and infrared radiation. This radiation travels through the vacuum of space until it reaches Earth's atmosphere, where some of it is absorbed and warms the surface of the planet. The heat is then further distributed through conduction, convection, and latent heat processes within Earth's atmosphere and surface.
What is one reason Earth's surface is heated unevenly?
Earth's surface is heated unevenly due to variations in solar radiation absorption caused by factors such as the angle of sunlight, albedo (reflectivity) of different surfaces, and distribution of land and water. These factors lead to differences in heating rates and result in uneven distribution of temperature across the surface of the Earth.
