Incident solar radiation (G
g
)
is the radiant solar energy that hits the earth’s surface and is referred as “global radiation” on a surface (W m
− 2
).
What is radiation outside the atmosphere called?
Defining power as the energy received per unit time,
solar irradiance
is the power per unit area outside our atmosphere received from the sun, and is also referred to as the solar intensity.
What is the radiation on Earth surface?
Infrared radiation
absorbed by Earth’s surface warms the surrounding air. Earth absorbs infrared radiation and converts it to thermal energy. As the surface absorbs heat from the sun, it becomes warmer than the surrounding atmosphere.
What type of radiation does the earth radiate back into outer space?
Earth returns an equal amount of energy back to space by reflecting some incoming light and by radiating heat (
thermal infrared energy
).
Which radiation does not reach the surface of the earth?
UVC rays
do not reach the Earth’s surface because they are completely absorbed by the atmosphere.
What event is caused by radiation hitting the Earth’s atmosphere?
Solar Events
Coronal mass ejections
happen on the outermost layer of the Sun’s atmosphere, called the corona and occur when the corona throws off plasma and electromagnetic radiation. Learn more about Radiation From Solar Activity.
Is radiation from the sun present in space?
Radiation in
space
takes the form of subatomic particles from the sun as well as from sources in the Milky Way galaxy and beyond. These high-speed particles tear through DNA molecules, splitting them or damaging the instructions they have encoded for cell reproduction.
What are 4 types of radiation from the sun?
Solar radiation includes
visible light, ultraviolet light, infrared, radio waves, X-rays, and gamma rays
.
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.
What does it mean when radiation passes through something?
Some of the radiation that hits the earth’s surface or atmosphere is reflected back into space. When radiation passes through something, it is
transmitted
.
Which helps to maintain a normal range of on Earth?
Answer Expert Verified. Answer:
Greenhouse gases
absorb radiation from the sun and re-radiate it back toward the atmosphere, which helps to maintain a normal range of temperature on Earth.
What is the ozone gas around the Earth called?
ozone layer, also called
ozonosphere
, region of the upper atmosphere, between roughly 15 and 35 km (9 and 22 miles) above Earth’s surface, containing relatively high concentrations of ozone molecules (O
3
).
What is considered longwave radiation?
emitted from Earth is called longwave radiation; it falls within the infrared portion of the spectrum and has
typical wavelengths of 4 to 30 micrometres (0.0002 to 0.001 inch)
. Wavelengths of radiation emitted by a body depend on the temperature of the body, as specified by Planck’s radiation law.
Which light is not seen from the Earth?
In addition to visible light, there are wavelengths that cannot be seen by the naked eye, such as radio waves and
infrared, ultraviolet, X-
, and gamma rays.
What 3 types of waves can be harmful to life?
The most dangerous frequencies of electromagnetic energy are
X-rays, gamma rays, ultraviolet light and microwaves
. X-rays, gamma rays and UV light can damage living tissues, and microwaves can cook them.
What three types of light are invisible?
Radio waves, X-rays and infrared rays
are comes in the invisible light. these wave length is shorter compare to visible light.
