The atmosphere begins at the Earth's surface (or the ocean's), and extends upward. Generally air density decreases with altitude, although temperature differences can alter that somewhat.

Is air denser near Earth's surface than high in the atmosphere?
Yes air is denser near the earth's surface than high in the atmosphere. The farther up air rises, there are less molecules of air between the outer edges of the atmosphere. This means there is a lot less air weighing down. A general rule of thumb is the higher the altitude, the lower the pressure: the lower the altitude, the higher the pressure.
What does the absorption of thermal energy from the ground do to earths surface?
The absorption of thermal energy from the ground heats the lower atmosphere and keeps Earth's surface much warmer than it would if there were no atmosphere. :)
Are rocks on the moon denser than rocks on earth?
The earths density is on average 5.5 g/mL. Surface rocks have an average density of 2.8 g/mL.
Why are there 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.
Which layer of the earths atmosphere contains no wate vapor has an atmosphere pressure less than 1.0 atmosphere and has air temperature that increases wth altitude?
Its the hydrosphere
Which moon is denser than atmosphere of earth?
All moons are denser that earths atmosphere

What is it about atmosphere on Earth for balloons to lift?
The earths atmosphere is denser than the helium found in a baloon therefore the baloon is lighter and is lifted above the denser air located in earths atmosphere. Which is why if you just blow up a baloon with air from your lungs it does not float. It would be the same density as the air outside of the baloon.
Is Venus' atmosphere heavy?
I'm not sure what a "heavy" atmosphere is but Venus' atmosphere is denser than Earth's and the atmospheric pressure at the surface is much greater than Earth's
Why do seismic waves speed up beneath the surface of continents?
Because earths crust is denser than the mantle
Why does water float on Earth's surface?
Oceanic crust is denser than continental crust, it floats lower in earths mantle.
The Earth's surface absorbs more radiant energy from the sun than the atmosphere?
yes the earths surface absorbs more radiant energy from the sun than the atmosphere GOOD LUCK :)
Why is there so much more pressure exerted on the earths core than the earths surface?
Pressure is the weight of an overlying column of material. The pressure at the core comes from 6400km of overlying rock, which is much denser than air
What does the absorption of thermal energy from the ground do to earths surface?
The absorption of thermal energy from the ground heats the lower atmosphere and keeps Earth's surface much warmer than it would if there were no atmosphere. :)
What would happen if carbon dioxide methane and water vapor were not in the atmosphere?
The Earths surface would be much colder than it is.
How was Mars was once similar to Earth?
We now know that Mars once had liquid water on its surface and probably had a much denser atmosphere than it does now.
What planet has a poisonous atmosphere than is so thick and acidic than even probes have trouble landing on its surface?
Venus. It has a very think atmosphere that means its surface pressure is around 93 times that of Earths. Probes have landed on its surface, but due to the extreme pressure, temperatures and hostile atmosphere, they don't last for very long.
