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
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 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.
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.
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
Why does radiation cause day and night?
Radiation from the sun causes day and night by Earth's rotation. As Earth rotates on its axis, different parts of the planet are either exposed to sunlight (day) or in shadow (night). This rotation creates the cycle of day and night that we experience on Earth.
Why is it colder at night than day?
At night, the Earth's surface loses heat to the atmosphere through radiation. Without the sun's warmth during the daytime, the Earth's surface cools down, leading to lower temperatures at night. Additionally, there is less solar radiation reaching the Earth's surface at night, contributing to the drop in temperature.
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.
What heats up the earth during the day and what cools it down at night?
During the day, the Earth is heated primarily by the sun's radiation. At night, the Earth cools down as it releases the heat absorbed during the day back into the atmosphere through a process called radiation cooling.
Is there any infrared radiation at night?
yes, the earth radiates heat as IR into space and gets cooler at night.
How does the earth cool down during night?
At night, the Earth cools down by radiation as heat from the surface is emitted into the atmosphere. This radiation escapes into space, causing the temperature to drop. Clear skies with low humidity allow for more efficient cooling because there are fewer clouds and water vapor to trap the heat at the surface.
Why cant you see the sun at night time?
You can't see the sun at night because the Earth is blocking the sunlight from reaching your location. During the night, the side of the Earth you are on is facing away from the sun, so it's dark.
What could decrease Earth's temperature?
Lower solar input & higher infrared radiation at night could decrease Earth's temperature.
