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.
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.
The absorption of thermal energy from the ground warms the Earth's surface, leading to an increase in temperature. This can contribute to changes in weather patterns, melting of ice caps, and other climate-related impacts on the environment.
The atmosphere traps energy from the sun because in our atmosphere are greenhouse gases, like carbon dioxide (CO2) and methane. These three-atom gases absorb the heat rising from the earth's surface.
Yes, rocks on the Moon are generally denser than rocks on Earth. This is because the Moon lacks the same geological processes that can alter rock compositions and densities over time, resulting in more uniform-density rocks.
1 percent of the earths atmosphere is made of the following: - Argon (0.93%) - Carbon dioxide (0.03%) - Neon> trace - Helium> trace - Methane> trace - Krypton> trace - Xenon> trace - Hydrogen> trace - Ozone> trace 21% of earths atmosphere is made of oxygen 78% of earths atmosphere is made of nitrogen
All moons are denser that earths atmosphere
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.
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
Because earths crust is denser than the mantle
Oceanic crust is denser than continental crust, it floats lower in earths mantle.

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
The Earths surface would be much colder than it is.
No, the Earth's atmosphere extends much higher than 1 kilometer above its surface. The exosphere, the outermost layer of the atmosphere, extends up to 10,000 kilometers above the Earth's surface.
We now know that Mars once had liquid water on its surface and probably had a much denser atmosphere than it does now.
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.
