The percentage of radiation reflected by an object is called that objects albedo. High albedo is very reflective, low albedo means most of the light that strikes the object will be absorbed.
The percentage of solar radiation reflected from a surface is called the albedo.

What percentage of the solar energy the reaches the outer atmosphere is absorbed at the earth's surface?
Roughly 70% of the solar energy that reaches the outer atmosphere is absorbed by the Earth's surface. The remaining percentage is reflected back into space by clouds, aerosols, and the Earth's 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.
The atmosphere is heated chiefly by radiation emitted by Earth?
This statement is incorrect. The atmosphere is heated primarily by the sun's radiation that enters the Earth's atmosphere. Some of this solar radiation is absorbed by the Earth's surface and then re-radiated as infrared radiation, which is partially trapped by greenhouse gases in the atmosphere, causing warming. This process is known as the greenhouse effect.
Which type and color of land surface would reflect the most solar radiation?
The Solar System object with the highest albedo is Europa with a reflectivity of 0.64. Earth by comparison is 0.367. Europe is smooth and covered in fresh (clean) ice. So smooth and white would reflect the most.
What happened to the solar radition?
Solar radiation is absorbed by Earth's atmosphere, surface, and oceans. Some of it is reflected back into space, some is absorbed and later re-emitted as heat, and some is converted into chemical energy through photosynthesis by plants. Some is also reflected directly back into space by clouds, snow, ice, and other reflective surfaces.
About 6 percent of solar radiation is what by the Earth's surface?
About 6 percent of solar radiation is absorbed by the Earth's surface, with the remaining percentage being reflected back into space or absorbed by the atmosphere.
How much solar energy is reflected by the atmosphere and earth's surface?
Approximately 30% of the incoming solar radiation is reflected back into space by the atmosphere and Earth's surface. This reflection plays a crucial role in regulating the Earth's temperature and balancing the energy budget of the planet.
What percentage of solar radiation reaches the earth and drives the hydro logic cycle?
About 50% of the incoming solar radiation reaches the surface of the planet. The rest is reflected or absorbed by the atmosphere & clouds, and a small portion is reflected by the oceans and land.
Solar radiation that is not reflected is absorbed by what?
Solar radiation that is not reflected is absorbed by the Earth's surface, where it heats up the land, water, and atmosphere. This absorption of solar energy drives processes like photosynthesis, weather patterns, and ocean currents.
How is 34 percent of the energy from the sun reflected off the troposphere?
The interaction of the sun's energy with the troposphere is complex. Approximately 30% of the incoming solar energy is reflected back to space by clouds, atmospheric particles, and the Earth's surface. The remaining 70% is absorbed by the Earth’s surface and then re-radiated as heat back into the atmosphere.
How much solar energy is reflected by clouds and other particles?
About 19% of incoming solar radiation is absorbed by clouds and the atmosphere.Incoming solar radiation: 100%Reflected by the atmosphere: 6% : Absorbed by the atmosphere: 16%Continuing incoming solar radiation: 78%Reflected by clouds: 20% : Absorbed by clouds: 3%Continuing incoming solar radiation: 55%Reflected by the earth's surface: 4% : Absorbed by the earth's surface (lands and oceans): 51%Source: (NASA)
What happens as solar radiation travels towards earth?
Some is absorbed by molecules in the atmosphere (such as ultraviolet absorption by ozone), some is absorbed on the surface, and some is reflected by clouds or the surface back into space. The surface will re-radiate much of the absorbed solar radiation as infrared (thermal) radiation, and some of this is then absorbed by atmospheric gases such as carbon dioxide and methane.
What term is used to describe incoming solar radiation?
25% is absorbed by clouds.25% is reflected by clouds.45% is absorbed by the earth's surface.5% is reflected by the earth's surface.So 50% reaches the surface of the earth (But 5% of that is reflected).
How much solar energy is reflected back into space?
On average, about 30% of the solar energy that reaches Earth is reflected back into space, primarily by clouds, ice, and snow-covered surfaces. This reflection, also known as albedo, plays a crucial role in regulating the planet's temperature and climate.
What percent of the Sun's energy intercepted by the Earth is absorbed by the atmosphere and clouds?
This Answer is as Variable, considering all of the varying Parameters, as it is Crucial to Our Tenuous Situation. This percentage, as Critical as it is, in not predictable as the Output of Solar radiation is as unknowable as the powerful Incidence of detrimental Cosmic Rays.
What percent of incoming radiation from the Sun is absorbed by Earth's surface?
Approximately 51% of incoming solar radiation is absorbed by Earth's surface. The rest is reflected back into space or absorbed by the atmosphere.
What is reflectivity of a surface called?
One term often used in Astronomy is the albedo. It refers to the percentage or fraction of incoming light that is reflected.
