The Earth receives 174 petawatts [See Link] of incoming solar radiation (insolation) at the upper atmosphere. Approximately 30% is reflected back to space while the rest is absorbed by clouds, oceans and land masses. For a pictorial description of insolation losses [See Link]
What else can I help you with?
How much radiation is absorbed by the earths surface?
The amount of radiation absorbed by the Earth's surface varies depending on factors such as location, time of day, and cloud cover. On average, about half of the solar radiation that reaches the Earth's atmosphere is absorbed by the surface, where it is then transformed into heat energy.
What Half of earths surface is called?
There is no such thing as half of the Earth. If you are referring to half of the spherical shape of the Earth then it will be a hemisphere.
What happens to solar energy as it enters the atmosphere?
About half of it is absorbed, reflected, or scattered within the atmosphere. The remainder reaches the earth, where it heats it. This radiation emitted by the earth heats the lower atmosphere and generates the earth's weather.A:Some is absorbed to make ozone (UV-C and more energetic), some is absorbed to break ozone back down (UV-B and more energetic). Some is absorbed and radiated back to space (infrared and less energetic) or captured by greenhouse gases. Lots of it is passed down to Earth's surface (UV-A thru the near infrared).
How does the angle of light affect the temperature of a surface?
The amount of energy reaching a given area from a source of radiant energy is dependent on the angle of incidence of the energy. Radiation that contacts a surface at an angle of 60° from the normal has half as much energy per unit of surface area as radiation that is parallel to the normal, radiation that reaches the surface at 70.53° from the normal has one third the energy per unit of area, radiation at 75.52° from the normal has one fourth as much energy, and so on. Therefore, if light is contacting a surface that absorbs some of it and converts it to heat, the angle of incidence of the light will affect the temperature. Such is the reason why winters are colder than summers.
The lower atmosphere is directly warmed from?
It's warmed from the surface. Shortwave radiation passes through the atmosphere, or at least about half of it, where it reaches the ground and is absorbed. The ground re-emits it at a longer wavelength, thereby warming the lower atmosphere.
How much radiation is absorbed by the earths surface?
The amount of radiation absorbed by the Earth's surface varies depending on factors such as location, time of day, and cloud cover. On average, about half of the solar radiation that reaches the Earth's atmosphere is absorbed by the surface, where it is then transformed into heat energy.
What percentage of the sun energy that reaches earth is absorbed by earth surface?
About 50 percent of the Sun's incoming energy is absorbed by the Earth's surface. In addition, about 9 percent is reflected.About 22 percent of the Sun's incoming energy is reflected by clouds and the atmosphere.About 19 percent of the Sun's incoming energy is absorbed by clouds and the atmosphere.
Would more of the suns energy reach the earths surface on a sunny day or a cloudy day?
More energy will reach the surface on a sunny day. Clouds reflect about half of the light that hits them, and this energy goes back into space.
What Half of earths surface is called?
There is no such thing as half of the Earth. If you are referring to half of the spherical shape of the Earth then it will be a hemisphere.
What is half of the sphere that makes up earths surface?
hemisphere.
What is One half of a spere that makes up the earths surface?
Hemisphere
What is half of the earths surface called?
A hemisphere is one half of the sphere that makes up Earth's surface.
Is there more land or water on earths surface?
Roughly 71% of Earth is covered by water and because that is well over half there is more water than land on Earths surface
Is the Earth one half land land or not?
the earths surface is 80% water. so no.
What is a rounded shape somewhat like a half ball?
A hemisphere.
Which ocean covers nearly half the earths surface?
The Pacific Ocean contains about half of the world's ocean water.
How much of the moons surface can be seen from the earths surface when full?
The Moon is roughly spherical; weather permitting, we see the near half of the Moon.
