the atmosphere
The definition of atmosphere is: all of the gasses that surround and envelope the earth. The atmosphere includes many different layers but to answer your question, yes.
Certainly not all of it, otherwise the earth would be inhabitable. Much as Venus is.
humans and people on earth consume all types of products that produce gases that are released into the atmosphere. These heat trapping gases are mainly caused by fossil fuels
The natural greenhouse effect, helped by greenhouse gases and the carbon and water cycles of the earth keep the atmosphere warm. Greenhouse gases keep back some of the sun's heat so it doesn't radiate back out to space. This has kept the earth warm for millions of years.
the 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.

you can see the presence of gravity all around as that is what holds us to the earth and gives us weight.
The gasses surrounding a planet is called an atmosphere and what gasses surround a planet depends on the planet. Earth's atmosphere is a combination of oxygen, nitrogen, argon and carbon dioxide and Saturn's atmosphere is comprised of hydrogen and helium.
The atmospheric gases carbon dioxide, methane and nitrous oxide are all greenhouse gases that help to heat the Earth.
The gravity from the sun "holds" the planets into place and make them orbit the sun. Just like the gravity from the Earth makes the moon orbit the Earth.
carbon
No. Earth is actually a mix of solid, liquid and gases. The solid is the Land we walk on, the liquid is the water and see we drink and swim in and the gas is the air all around us
The gases surrounding the Earth or any astronomical body is called the atmosphere.
Greenhouse gasses are all around us. In fact, you breathe out carbon dioxide every time you exhale, and when you drink water, you're conusming H2O, which in vapor form is also a greenhouse gas.
