The center of the earth is hot due to radioactive decay of long lived isotopes such as Uranium 235 and Potassium 40, and the insulating effect of all the iron and rock over-top of it. It gets so hot in fact that the iron down there melts and starts to rise, this sets up convection currents that form get cycling cells kind of like (only slightly so) bubbles in a boiling pot of water. These cycling cells of hot iron are what produce the earth's magnetic field.
These moving current of magma tend to push the surface rock around in slowly moving plates, these plates of moving rock are what the continents are on and therefore we have continental drift. The upwelling magma at the mid-Atlantic ridge and elsewhere produce chains of under=water volcanos that bring fresh elements to the ocean water that support life.
The leading edge of the moving continents buckle up and produce mountains on the land. These get eroded by weather and return nutrients to the sea.
Cyanobacteria are the group of organisms most responsible for changing the composition of Earth's early atmosphere. Through photosynthesis, they released oxygen into the atmosphere, fundamentally altering its composition and paving the way for aerobic organisms to evolve.

Yes, 80% of the Earths atmosphere is made up of nitrogen.
Nitrogen makes up 78% of the Earth's atmosphere.
Nitrogen has made up the largest portion of Earth's atmosphere for most of Earth's history. It currently makes up about 78% of the atmosphere.
how do geologists think earths atmosphere is formed
STRATOSPHERE
Thermosphere, it is also the atmosphere with the highest temperatures.
Meteoritesis what we call stones that enter the earths atmosphere.
There is no atmosphere on the Earth's moon.
What is the earths atmosphere made of
what causes all of the changes that take place in earths atmosphere is the tilt of the earths axis
No
pooo
Meteoritesis what we call stones that enter the earths atmosphere.
There is no atmosphere on the moon. There is insufficient gravity to keep an atmosphere there.
The Region of the Earth's atmosphere is the Homosphere.
