The atmosphere acts as a blanket, trapping heat from the sun and preventing it from escaping back into space. This process, known as the greenhouse effect, helps regulate Earth's temperature and keep it within a range that supports life. However, human activities are increasing the concentration of greenhouse gases in the atmosphere, leading to global warming and climate change.
What else can I help you with?
How does heat enter the atmosphere?
Heat enters the Earth's atmosphere primarily through the absorption of sunlight by the Earth's surface, which warms up and then radiates heat back into the atmosphere. Other sources of heat entering the atmosphere include human activities such as burning fossil fuels and deforestation, which release heat-trapping greenhouse gases.
What is the most effective greenhouse gas for trapping heat in the Earth's atmosphere?
The most effective greenhouse gas for trapping heat in the Earth's atmosphere is carbon dioxide (CO2).
What atmosphere in the air is warmed by heat from Earth's surface?
The lower atmosphere, known as the troposphere, is warmed by heat from Earth's surface. This warming is due to the absorption of outgoing radiation by greenhouse gases such as carbon dioxide and water vapor, which trap heat in the atmosphere.
Is the heat in space the same as the heat on earth?
No, the heat in space is very different from the heat on Earth. In space, there is no atmosphere to trap heat, so objects in direct sunlight can become extremely hot while those in the shade can become very cold. On Earth, the atmosphere helps regulate the temperature and distribute heat more evenly.
What is the process of earth's atmosphere trapping in heat?
The Sun's heat, which keeps Earth from freezing solid, is retained in Earth's atmosphere by the greenhouse gases: water vapor, carbon dioxide, methane, and so on. Without greenhouse gases, Earth would freeze.Many, if not all of the various layers of a planet's atmosphere trap at least some of the heat from the sun. Additionally, the ground and bodies of water trap heat from the sun (and heat from the atmosphere).
Why does the earth remain warm after sunset?
The surface of the earth holds heat, and the greenhouse gases in the atmosphere hold heat all through the night. If the earth had no atmosphere, then at night all the heat would escape out to space and the earth would be freezing.
Why does the earth not lose its heat as quickly at night as the moon does?
The Earth retains heat better due to its thicker atmosphere and higher heat capacity compared to the moon. The atmosphere acts as a barrier, trapping heat on Earth, while the moon has no atmosphere to retain heat, causing rapid heat loss at night.
Does the sun keep the earth warm?
The sun warms the earth. The heat (energy) from the earth then heats the air.
Does all heat radiated by the sun enters the atmosphere?
No. The sun radiates heat in all directions on 3 axes. The spherical arc of that which reaches the Earth's Atmosphere is very small in comparison.

What in the earth's atmosphere absorbs heat?
Greenhouse gases.
What is the process by which the earth's atmosphere absorbs heat?
sublimation
What is the process by which the earth atmosphere absorbs heat?
sublimation
How does conduction heat the atmosphere?
Conduction heats the atmosphere by transfer of heat from the Earth's surface to the lower atmosphere through direct contact. As the Earth's surface gets heated by the sun, it transfers some of that heat to the air molecules in contact with it. This process helps warm the lower atmosphere.
What is the most effective greenhouse gas for trapping heat in the Earth's atmosphere?
The most effective greenhouse gas for trapping heat in the Earth's atmosphere is carbon dioxide (CO2).
