How did comet collissions with the earth contribute to the composition of the atmosphere?
The subject of cometary collisions with the infant Earth are still the subject of debate. Some scientists believe that comet collisions would contribute too small a mass to add much to the atmosphere, while others suggest that long ago there would have been many more comets in the solar system, and that the reason we don't see them now is because they have already hit the Earth - and the Moon, and Venus, and Mars, and all the other planets.
The honest answer is, right now we don't know.

What is the composition of a comet?
The composition of a comet is frozen gases, dust, and rocks.
Does a comet have an atmosphere?
Comets do not have atmospheres in the same way that planets do. Instead, they have a thin envelope of gas and dust, called a coma, that forms as the comet gets closer to the Sun and begins to heat up. This coma can extend hundreds of thousands of kilometers from the comet's nucleus.

How can you differentiate a meteor from a comet when you viewed from earth?
The meteor is in the atmosphere and is only visible for seconds to minutes. The comet is much further away outside the atmosphere and can be observed for weeks to many months.

What is the earth's first atmosphere primarily compose of?
The Earth's first atmosphere was primarily composed of hydrogen and helium, similar to the composition of the solar nebula from which the Earth formed. Volcanic activity and comet impacts later contributed to the formation of the secondary atmosphere, rich in carbon dioxide and water vapor.
Does a comet burn when it enters the earth atmosphere?
Yes, a comet experiences intense heating and friction as it enters Earth's atmosphere, causing it to burn and create a bright streak of light known as a meteor or shooting star. This process is due to the extreme speed at which the comet is traveling through the atmosphere.
What is The cloudy atmosphere of a comet?
The nebulous halo around the nucleus of the comet is called the "Coma" ...The stream of dust and gas that extends away from the comet is called the"Tail".
