It is the closest one to the earth, so that's where the force of gravity is the strongest.
Gravity is strong enough to hold on to a large number of particles.
The exosphere is the least dense part of the earth's atmosphere.
The core. It's where all the heavy elements have been created from simpler atoms.
Earth isn't in the atmosphere - the atmosphere is part of Earth.
The word atmospheric is an adjective. It means to be coming from the atmosphere.
Free Atmosphere or Free Air is a part of the atmosphere that lies above the Earths frictional influence.
Troposphere is the most dense part because it is at the bottom of the atmosphere.
The exosphere is the least dense part of the earth's atmosphere.
I live in the deepest, thickest, warmest, most dense part of the column of atmosphere located over Chicago.
One could say that the atmosphere is the least dense, but of the surface the crust is the least dense.
hot, less dense air rises
Water in soil evaporates into a gas, then collects and turns dense forming clouds. Clouds are technically a part of the atmosphere.
Most of the rainforest is very dense, but the understory and canopy are both pretty dense. The canopy and the understory are both very dense but the undersrory is the most dense.
inner core
The nucleus is the most dense part of an atom.
Upper Part
The Inner Core is the most dense part of the Earth. It is a solid core of iron and nickel.
The air becomes less dense, the higher you go. And generally, the temperature gets colder until you reach the thermosphere, which is the hottest part of Earths atmosphere.
