What else can I help you with?
The major portion of which form of solar radiation is absorbed as it passes through the atmosphere with only a tiny fraction of the original amount reaching the surface of the earth?
ground radiation
The solar radiation least absorbed by the layers of the atmosphere before reaching Earth is?
Ultraviolet radiation is the solar radiation least absorbed by the layers of the atmosphere before reaching Earth. This is due to the ozone layer, which helps to absorb and block a significant portion of the incoming ultraviolet radiation.
What are two things that stop solar energy from reaching the ground?
Clouds and small particles of pollution, including volcanic emissions reflect some solar energy and prevent it reaching the ground.Ice and snow reflect the sun's energy too.The ozone layer also reflects some ultra-violet radiation.
Which process keeps solar energy from reaching the Earth and is measured by it's albedo?
The process that keeps solar energy from reaching the Earth and is measured by its albedo is reflection. Albedo refers to the fraction of solar energy reflected back into space by a surface, with higher albedo values indicating greater reflectivity. Surfaces such as clouds, ice, and snow have high albedo, reflecting a significant portion of incoming solar radiation, while darker surfaces absorb more energy. This reflection plays a crucial role in regulating the Earth's climate and temperature.
How does volcanic ash in Earths atomosphere affect solar radiation?
It blocks (some of) it from reaching the surface of the Earth.
What is a positive feature of the ozone layer?
It blocks Solar ultra-violet radiation from reaching Earth's surface.
What meter measures heat radiation?
A pyranometer is a device that measures the total solar radiation received from the sun. It is often used to quantify the heat radiation reaching the earth's surface.
Do polar latitudes have solar radiation deficit?
Yes, polar latitudes receive less solar radiation than equatorial latitudes due to the Earth's axial tilt. This results in colder temperatures and less direct sunlight reaching the poles, creating a solar radiation deficit in these regions.
What function provides insolation?
The function that provides insolation is solar radiation, specifically solar energy received by the Earth's surface. Insolation is the amount of solar radiation reaching a specific area over a given time period. It is an essential factor in understanding climate and ecosystems.
What is the term for the sun reflecting off the ground?
The term for the sun reflecting off the ground is called "solar reflection" or "ground reflection." This phenomenon can cause glare and increase the amount of sunlight reaching our eyes or solar panels.
Did the snow absorb rather than reflect solar radiation typically during an ice age?
No. Snow typically reflects much of the solar radiation reaching it, regardless of whether that is happening during an ice age or a warmer period.
What are the three things controlling the amount of solar energy reaching Earth?
The amount of solar energy reaching Earth is primarily controlled by three factors: the Earth's distance from the Sun, which varies due to its elliptical orbit; the Sun's output, which can fluctuate due to solar cycles; and the Earth's atmosphere, which can absorb or reflect solar radiation. Additionally, clouds and aerosols can influence how much solar energy reaches the surface. Together, these factors determine the overall solar radiation received by the planet.
