What Two Things Happen To Solar Radiation That Reaches Earth?
Once the sun’s energy reaches earth it is intercepted first by the atmosphere. A small part of the sun’s energy is directly absorbed particularly by certain gases such as ozone and water vapor. Some of the sun’s energy is reflected back to space by clouds and the earth’s surface.
What happens when radiation reaches Earth?
What happens to solar energy reaching the Earth?
About 30% of the solar energy that reaches Earth is reflected back into space. The rest is absorbed into Earth’s atmosphere. The radiation warms the Earth’s surface and the surface radiates some of the energy back out in the form of infrared waves. … This greenhouse effect keeps the Earth warm enough to sustain life.
What 2 things affect how much solar radiation heats the Earth’s surface?
The amount of heat a surface radiates is proportional to the fourth power of its temperature. If temperature doubles radiated energy increases by a factor of 16 (2 to the 4th power). If the temperature of the Earth rises the planet rapidly emits an increasing amount of heat to space.
What happens to solar radiation that reaches the Earth quizlet?
What happens to solar radiation after it reaches Earth? … – Nearly 70% of solar radiation is absorbed by the earth’s atmosphere and oceans and the rest is reflected back into space. The absorbed radiation is re-emitted as infrared radiation.
What happens when solar radiation enters Earth’s atmosphere?
How does solar radiation reach Earth’s surface?
Solar radiation reaches earth’s surface as (1) direct (beam) solar radiation (2) diffuse solar radiation and (3) reflected radiation which can be neglected. The total radiation received from the sun of a horizontal surface at the level of the ground for a serene day is the sum of the direct and diffuse radiations.
What is the solar radiation received by the Earth called?
What type of radiation does Earth emit?
What is solar radiation in geography?
Solar Radiation (definition)
Solar radiation is radiant energy emitted by the sun from a nuclear fusion reaction that creates electromagnetic energy. The spectrum of solar radiation is close to that of a black body with a temperature of about 5800 K.
What are the 4 main effects of solar radiation on Earth?
- atmospheric effects including absorption and scattering
- local variations in the atmosphere such as water vapour clouds and pollution
- latitude of the location and.
- the season of the year and the time of day.
How does solar radiation affect Earth’s climate?
Researchers have shown that UV radiation affects climate through direct heating and the production and destruction of ozone in the stratosphere which then leads to regional effects at Earth’s surface through a complex chain of mechanisms.
What type of radiation is solar radiation?
All of the energy from the Sun that reaches the Earth arrives as solar radiation part of a large collection of energy called the electromagnetic radiation spectrum. Solar radiation includes visible light ultraviolet light infrared radio waves X-rays and gamma rays. Radiation is one way to transfer heat.
What happens to solar radiation after it reaches the Earth How do greenhouse gases warm the lower atmosphere?
What is the fate of solar radiation after it reaches Earth? … After absorbing radiation emitted from the surface greenhouse gases re-emit infrared radiation. Some of this re-emitted energy is lost to space but most travels back downward warming the lower atmosphere and the surface (greenhouse effect).
What happens to solar energy when a Faculae occurs quizlet?
Although sunspots reduce the amount of energy radiated from the Sun the faculae associated with them increase the radiated energy even more so that overall the total amount of energy emitted by the Sun increases during periods of high sunspot activity.
What happens to 99 of the energy that reaches Earth’s atmosphere quizlet?
***What keeps 99% of the total mass of the atmosphere within 32 km of Earth’s surface? Most are absorbed by earths land ocean surfaces and by atmosphere. The remainder is reflected back into space.
What influences solar radiation?
The intensity of the solar radiation at a given location depends on your latitude terrain season time of day and atmospheric conditions. For example clouds dust and water vapor all affect the amount of radiation that reaches the surface at any given location.
What is the of solar energy reaching the earth surface?
…
The Solar Energy Resource.
| Solar constant at the distance of the earth from the sun | 1367 W/m2 |
|---|---|
| Total solar flux reaching earth | 1.08×108 GW |
What are the two basic ways to measure solar radiation?
Explanation: Thee two basic ways to measure solar radiation are via ground-based instruments and satellite measurements.
Which two bands of solar radiation are majority in the total solar radiation reaching the Earth?
Which two bands of solar radiation are majority in the total solar radiation reaching earth? Explanation: Infrared and UV are the major components of the total solar radiation reaching earth. Infrared radiation makes up 49.4% and visible light makes up 42.3%. Only 8% of the total radiation is in the UV band.
Where is solar radiation highest on earth?
The equator
The equator receives the most solar radiation in a year. The difference in the amount of solar energy the land receives causes the atmosphere to move the way it does.
What is reflected solar radiation?
What is the effect of solar radiation into human and to other species like plants and animals?
In humans and animals prolonged exposure to solar UV radiation may result in acute and chronic health effects on the skin eye and immune system. UVB exposure induces the production of vitamin D in the skin.
How is radiation affecting the Earth’s temperature?
When visible light and high frequency infrared radiation are absorbed by the surface of the Earth the planet’s internal energy increases and the surface gets hotter. … Some of this infrared radiation is transmitted through the atmosphere back out into space and some is absorbed by greenhouse gases in the atmosphere.
What happens when absorbed solar radiation increases?
As greenhouse gases including carbon dioxide increase in the atmosphere the increase in radiative forcing results in higher surface temperatures increased water-holding capacity of the atmosphere increased evaporation and larger water vapor amounts.
How does solar radiation affect the water cycle?
What happens if a surface absorbs solar radiation quizlet?
Higher atmospheric heat absorption leads to higher surface temperatures because with more radiation absorbed than emitted the surface and atmosphere warm. This is also due to counter radiation heat from the atmosphere supplies more than twice as much heat to the surface as the sun.
What do interactions between solar radiation and the ionosphere cause?
– Interactions between solar radiation and the ionosphere cause the phenomena known as auroras. … – This zone of indefinite altitude is called the exosphere and extends for thousands of kilometers above the ionosphere.
Where does the sun’s energy come from how is it released into space quizlet?
Energy is transported outward by the rising of hot plasma and the sinking of cooler plasma. Most of the energy produced in the Sun is released in the form of visible light from the photosphere. However some energy is released from the upper layers of the solar atmosphere.
What happens to 99% of the energy that reaches Earth’s atmosphere?
Between 98 and 99 percent of solar energy reaching Earth is reflected from leaves and other surfaces and absorbed by other molecules which convert it to heat.
What are two examples of what happens when energy from the sun reaches Earth?
Energy released from the Sun is emitted as shortwave light and ultraviolet energy. When it reaches the Earth some is reflected back to space by clouds some is absorbed by the atmosphere and some is absorbed at the Earth’s surface.
What solar energy reaches Earth it is in the form of quizlet?
The sun’s energy reaches earth in the form of radiation. 99% of radiant energy from the sun consist of visible light and infrared radiation. Radiation is the transfer of energy by electronic waves. You just studied 16 terms!
