What percentage of incoming solar radiation is reflected back into space by plants?

∙ 10y ago
About 45% of the sun's energy is reflected back into the greenhouse gases in the atmosphere from the energy (51%) absorbed by the earth's surface (lands and oceans). Clouds and the atmosphere have already absorbed another 19% of the incomingradiation.
Conduction and rising air take 7% into the atmosphere.
Latent heat in water vapour takes 23% into the atmosphere.
Directly radiated from earth is 15% into the atmosphere.
(The remaining 6% is directly radiated out to space.)

Why is methane such a potent greenhouse gas?
Because it can kill people and plants like in cigarettes. Because it prevents re-radiation of Incoming EM radiation; similar to CO2.
What percentage of the earth's surface is covered by plants?
32.7%
What is percentage of plants on earth?
The 37 wilderness areas claim that 46% of earth is covered by plants
What percentage of the earth's land surface is covered by plants?
I think 70-80 % of the planet is water. That would make roughly less than 30% covered by plants.
How does the greenhouse affect happen?
The sun shines light onto the Earth. The Earth (and different surfaces on it- plants, oceans, blacktop, etc...) absorbs most of the energy but some is reflected back out into space. Greenhouse gases trap the reflected energy and keep it in the atmosphere, raising Earth's temperature. The more these gases are created, the more the Earth's temperature rises.
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 happens to heat energy as it reaches the earth?
Some solar radiation is reflected back into space and some is absorbed.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 is the definition of radiation use efficiency and light use efficiency?
radiation use efficiency is the percentage part of incident solar radiation spectrum being utilized by plants.
Wikianswers why is a green house hot?
it heats up because incoming solar radiation from the sun and it warms the soil which makes humidity and helps the plants stay hydrated
Why is radiation important to plants?
Plants depend on solar radiation (light) to synthesise their energy.
How do animals get solar radiation by eating plants?
The plants absorbs the solar radiation and energy.
Is energy absorbed or reflected by earth?
The solar energy that reaches the Earth is called insolation.Of the incoming solar radiation 16% is absorbed by the earth's atmosphere, 3%is absorbed by clouds and 51%is absorbed by the earth's surface, making a total of 70%.
What are the three things that happens to the radiation the Earth receives from the sun?
It is reflected back out into space (e.g off clouds)It is captured by plants in photosynthesisIt warms the air and makes the weather systems on Earth and the ocean circulationsIt becomes trapped (over time) as fossil fuels.
What do you know about nuclear plants?
Nuclear Plants give off radiation, however when some of the nuclear plants in Japan were destroyed, some of the radiation did travel here but the radiation it sent here isn't strong enough to do any damage :)
What happens to the energy from the sun that is absorbs by earths surface?
Energy from the sun that is absorbed by the Earth's surface is reflected back into the atmosphere or absorbed by land and water and transformed into heat.
What problems did the radiation solve?
it solved plants
