Gravity.
The Earth's atmosphere is kept in place by gravitational pull the Earth exerts on particles in the atmosphere. But part of the Earth's atmosphere does float out into space. The part that is lost out into space is the extremely light particles like Hydrogen which can escape the Earth's gravity.
Yes, Earth's gravitational force holds our atmosphere in place. The gravitational force between Earth and the atmosphere prevents it from drifting off into space. The atmosphere is made up of gases like nitrogen, oxygen, and carbon dioxide, which are all kept close to Earth's surface due to gravity.
The atmosphere of the Earth is held in place by Earth's gravity.
Weather is the condition of Earth's atmosphere at a particular time and place.

condition of earth's atmosphere at a particular place and time
The condition of the earth's atmosphere at a particular place is called "Weather".
The ozone layer is kept in place by the Earth's stratosphere, a region of the atmosphere where temperature increases with altitude. This temperature gradient prevents the ozone from drifting away and helps it to remain concentrated in the stratosphere.

Like all weather events on earth, tornadoes take place within and as a part of earth's atmosphere. They are produced by thunderstorms, which are driven by thermodynamic instability in earth's atmosphere.
condition of earth's atmosphere at a particular place and time
The earth's atmosphere is not hot enough for thermonuclear fusion to take place.
