Can comets hit the Earth's surface? Yes but they would have to be above a certain size so as not to burn up high in our atmosphere. You shouldn't worry though ...
The scientific term for a shooting star that hits Earth's surface is a meteorite. It is a solid piece of debris from a comet, asteroid, or meteoroid that survives its passage through the Earth's atmosphere and impacts the surface.
The Earths surface would be much colder than it is.
there would be nothing, less than mercury, because mercury's atmosphere is a foot off of its surface.
Yes, 80% of the Earths atmosphere is made up of nitrogen.

If there were no greenhouse gases in the atmosphere, Earth's average temperature would be significantly colder. Greenhouse gases like carbon dioxide and methane trap heat in the atmosphere, helping to keep the planet warm. Without them, Earth's surface would not retain as much heat from the sun, resulting in much lower temperatures.
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.
No. If a comet were to strike the Earth, the results would probably be catastrophic.
There is good ozone and then there is bad ozone. Good ozone is present in the earth's atmosphere.
The surface of the earth holds heat, and the greenhouse gases in the atmosphere hold heat all through the night. If the earth had no atmosphere, then at night all the heat would escape out to space and the earth would be freezing.
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.
