Did the elements in the atmosphere come from the erosion of rock and outgassing?

No. Most of the atmosphere is primal - it was collected together in the accumulation that became Earth. Much of it is manufactured in stars and novae.

Where is the early atmosphere thought to have come from?
It comes from the process of planetary differentiation. light elements such as nitrogen rise up to form the atmosphere,whereas heavy elements such as iron sink to the mantle.
What is the driving force for erosion?
the driving force for erosion is , when bad things come out of driving that involves erosion.
Why does erosion happen before deposition?
Without erosion of particles, deposition (depositing) would have no particles to deposit. So erosion must come first.
What layer in the atmosphere do meteors come from?
Meteors come from outer space and crash into our atmosphere which burns them. That's what a shooting star is.
Compare and contrast weathering and erosion?
Factors: Erosion occurs because of factors like wind, water, ice, human activities like deforestation etc. Weathering, on the other hand is caused by contact with the earth's atmosphere. These atmospheric conditions may be heat, pressure etc. Movement: Erosion is caused by the movement of eroding agents while in weathering there is no movement. Weathering is caused when rocks come in contact with atmospheric conditions but there is no movement involved of either of the components.
Are both weathering and erosion a form of tectonic forces?
No. Tectonic forces are from within the earth. Weathering and erosion come from the atmosphere.

Where do the elements in the sun's atmosphere come from?
Any elements in the sun's atmosphere other than hydrogen or helium were provided by earlier supernovas that exploded before the sun formed.The hydrogen and much of the helium in the sun's atmosphere originated directly in the big bang and have not changed since then.Some of the helium in the sun's atmosphere passed up in convection currents from the sun's core where it is fusing hydrogen to helium.
How does oxygen occur?
If you mean how does it come to be in the atmosphere, oxygen is released into the atmosphere by plants, mostly by phytoplankton in the ocean. I you mean how is oxygen created in the first place, it is the result of lighter elements being fused together in the cores of stars.
Does most Sediment come from weathering?
No, it is erosion.

Without erosion of particles, deposition (depositing) would have no particles to deposit. So erosion must come first.
Where sediment come from?
Sediments come from the erosion of igneous, sedimentary, and metamorphic rocks.
Does the atmosphere come from the sun?
No it does not. Atmosphere comes from the earth itself.
Where did the white quartz sand on Florida beaches come from?
erosion

Where do these main gases come from?
they come from earths atmosphere and gases
