What is earth's upper atmosphere?
The atmosphere of Earth is a layer of gases surrounding the planet Earth that is retained by Earth's gravity. The atmosphere protects life on Earth by absorbing ultraviolet solar radiation, warming the surface through heat retention (greenhouse effect), and reducing temperature extremes between day and night (the diurnal temperature variation).
What does an infrared satellite image show?
radiation emitted by objects during the day and night
What type of energy is emitted from earth to the atmosphere?
Simple Answer:Most of the energy emitted from the Earth is infrared energy, just below the visible spectrum we can see. A portion of this energy is absorbed by the atmosphere, particularly by water vapor and carbon dioxide in the Earth's atmosphere.Planets have some heat.The Earth and other planets retain some residual heat left form the time planets and the Sun were formed four or five billion years ago. In addition, there are some internal sources of heat such as radioactive decay. Earth and other planets also gain heat from the Sun.Planets lose heat.Overwhelmingly, the mechanism for heat loss is through radiation of heat. All objects radiate heat in the form of electromagnetic radiation. (One can look up "black body radiation" which is an interesting topic in its own.) For Earth, this is typically characterized as infra-red radiation. The radiation is emitted from the Earth, through the atmosphere and heads out into cold space.(Space, all the apparent emptiness we see in the night sky, is at a temperature of about 4 degrees Celsius above absolute zero, compared to our temperature of almost 300 degrees above absolute zero. The cooling through radiation of the hot Earth is evident in our daily lives because the cooling we experience at night can be so dramatic. In particular, clouds prevent much infrared radiation from directly escaping. A cloudy night cools several degrees less than a clear night.)There are complications.Though there is no question that the Earth loses heat by radiating it into space, the details get complex. There are a lot of complications about how much energy of this sort is absorbed by the atmosphere and that leads to discussions of the Greenhouse Effect, but that can be left to another question. There is a complex balance of energy incoming and energy radiated that can occupy a long discussion.
How cold is it at night on earth?
I is about 4.4
What cause the earth day night?
First understand that night is caused when a point on a planet rotates with the planet so that it is not pointing towards the sun (it rotates into the shadow of its planet). When it is pointing towards the sun it is day!On Earth as the planet rotates once on its axis every 24 hours, a point on its surface will be in shadow for 12 hours at a time and in daylight for the other 12 hours.------------------------------------------------------------When the Earth spins around on its axis, it creates night and day on Earth. This movement makes it look like the Sun is moving across the sky. The Sun rises in the east and sets in the west, turning day into night.Most places on Earth have some amount of day and night every 24 hours. On Earth, the length of day and night usually changes with the seasons.When your location on Earth is facing toward the sun, it is day. When your location is facing away from the sun, it is night.Only the half of the rotating Earth that faces the Sun is illuminated at any given time.
What is the form of radiation released by Earth at night?
The form of radiation released by earth at night is gamma rays.
What is the main form of radiation released by earth at night?
The form of radiation released by earth at night is gamma rays.
How does the earth cool down during night?
Heat (infra red radiation) radiates into space at night, cooling the earth.
Why is it warmer during the day than the night?
the day is warmer than it is at night is because, during the day the sun gives out heat waves (this is called radiation) to the earth. But at night the sun radiation is shining at the oppsite of the earth.
At night the radiation balance is usually?
The radiation balance at night is negative. This is due to the fact that the shortwave radiations are not radiating at night because the earth is colder than the sun.
The temperature of the air falls at night because the earth loses heat by?
The temperature of the air falls at night because the earth loses heat by
Is there any infrared radiation at night?
yes, the earth radiates heat as IR into space and gets cooler at night.
Why is mars visible from earth in the night sky?
No light from the Sun is reaching the dark side, once you look in the night sky it would be easier to look at Mars because no light is reaching the side you are on or Mars.
If the sun faces north will it be night in the east?
yes, all stars the sun and moon rise in the east and set in the west, this is due to the rotation of the Earth
What heats up the earth during the day and what cools it down at night?
The suns radiation heats up the earth during the day
What could decrease Earth's temperature?
Lower solar input & higher infrared radiation at night could decrease Earth's temperature.
What heats up the earth during the day and cools it down at night?
The suns radiation heats up the earth during the day
