Solar radiation mostly passes through the atmosphere without heating it, due to its wavelength. It does not pass through the ground, however, and it heats the ground. The ground emits radiation at a wavelength dependent on its temperature. This radiation happens to be in the thermal infrared part of the spectrum, or in other words, sensible heat. Therefore, the atmosphere is heated by the surface, whereupon the heat tends to rise and heat the lower atmosphere.

What is earths mantle heated by?
Earth's mantle is mainly heated by the decay of radioactive isotopes and residual heat from the formation of the planet. This heat causes convection currents in the mantle which drive plate tectonics and other geological processes.
Is Jupiter atmosphere thicker or thinner then earth?
Jupiter's atmosphere is much thicker than Earth's. It is composed mainly of hydrogen and helium and extends thousands of kilometers above the planet's surface, making it one of the largest atmospheres in our solar system.
How many miles thick is the atmosphere of Venus?
venus has thick posnis atmosphere
Why are there are almost no extrusive ultra basic rocks in earths crust?
There are almost no extrusive rocks on the earths surface because they are all under the earths surface. They are mainly lower than the earths surface.
Does planet Mars have an atmosphere?
Yes it does, its atmosphere is mainly full of carbon dioxide.
Earths atmosphere is heated mainly by what?
The sun as it is the most powerful heat source in our solar system.
Explain why earths troposphere is mainly heated from the ground up?
The Earth's troposphere is mainly heated from the ground up because the Earth's surface absorbs more sunlight than the atmosphere, causing it to warm up. This warmth is then transferred to the air immediately above the ground through conduction and convection, creating a temperature gradient with the surface being warmer than the higher altitudes.
Explain why earth's atmosphere is mainly heated from the ground up?
Earth's atmosphere is mainly heated from the ground up because the heat is absorbed into the ground. The warmed surface of the earth then emits heat as infrared radiation which rises into the atmosphere. There the greenhouse gases like water vapour, carbon dioxide and methane absorb and hold the heat.
Earth's atmosphere is mainly heated by?
The sun as it is the most powerful heat source in our solar system.
What is the atmoshphere like in the inner planets?
Mercury has no real atmosphere, so it's a bit like the moon in that respect. Venus has a very thick atmosphere of mainly carbon dioxide, it has a huge surface pressure of around 93 bar, around 93 time that of earths. Earths atmosphere is mainly nitrogen (79%) and oxygen (20%) with some carbon dioxide (1%) roughly speaking. Mars has a thin atmosphere, mainly carbon dioxide.
How does the earth and it's atmosphere get heated?
The Earth's atmosphere gets heated mainly through the process of solar radiation. Energy from the sun is absorbed by the Earth's surface, which then radiates heat energy back into the atmosphere. Greenhouse gases in the atmosphere also trap some of this heat, leading to the warming of the planet.
What is earths mantle heated by?
Earth's mantle is mainly heated by the decay of radioactive isotopes and residual heat from the formation of the planet. This heat causes convection currents in the mantle which drive plate tectonics and other geological processes.
What is the most common gas on mars?
Mars has an atmosphere but it is much thinner than earths. It's mainly carbon dioxide gas (95%).
Does Venus have an atmoshpere?
Yes, an incredibly dense one. Mainly of carbon dioxide it is about 90 time more dense than the Earths atmosphere.
What are the earths atmosphere facts?
1. there are five layers of the atmosphere 2. it is composed of the gas nitrogen (N) and oxygen (O) mainly 3. nitrogen (N) occupies 78% of the atmosphere 4. oxugen (O) occupies 21% of the atmosohere
Is gasoline heavier than atmosphere?
Gasoline is made up of chains of hydrocarbons while the atmosphere is mainly comprised of light gases. Proof: Pour a cup of gasoline on the ground, it displaces the lighter atmosphere.
Earths atmosphere is dominated by which two gases?
Nitrogen and Oxygen are the two main constituents of air.
