Two thing slow the balloon down. First, air friction opposes its upward movement. Second, as the balloon gets higher, the air around it gets less dense, so there's not as much force propelling the balloon upward.
what goes up, goes down!
Our Age!
When the hot air in a balloon cools down, it becomes denser and contracts. This causes the volume of the balloon to decrease, resulting in a decrease in buoyancy and making the balloon start to descend. The rate of descent will depend on factors such as the rate of cooling and the weight of the balloon.
rain goes down, but never goes up actually it evaporates is transformed to water vapor goes into the clouds and eventually comes down as rain again (pixilated)
Think of a balloon. Let some air out and the pressure goes down, and the balloon decreases in size.

The Balloon Goes Up was created in 1942.
If a balloon is squeezed, then that means the volume is decreasing. Volume and pressure vary indirectly, which means that when one goes up, the other goes down. So when you are decreasing the volume of the balloon, the pressure inside is going up (assuming constant mass and temperature).
it pops and goes every where dont try it.
Altitude is controlled by the propane burner and the parachute valve. The parachute valve is an opening at the top of the balloon envelope. When closed, it traps hot air from the burner inside the balloon, making the hot air balloon rise. When opened, it allows hot air to escape, and the hot air balloon descends. The reason a hot air ballon rises is because the density of the balloon is less than the density of the surrounding air. Its the same thing as "why does a boat float". In the case of the balloon, the operator modulates the flame on and off to maintain the desired altitude - increase the flame, and the balloon goes up - decrease or shut off the flame, and the balloon goes down. A better metaphor to a boat is a submarine - add ballast and the submarine goes down - blow ballast and the submarine goes up.
