Stratosphere rises to a height of 10- 50 km of the ground. There is no certain distinction of layer in atmosphere.
They both rise up off the ground

Levitation is to rise or cause to rise into the air and float in apparent defiance of gravity.

Balloons filled with Helium rise because Helium is less dense than normal air. Hot air balloons lift off the ground because heat rises, and when the balloon is full of air of a higher temperature than its surroundings, the balloon will rise.
because warm gases rise because they are less dense than normal air, so the hot air from the flame is trapped in the balloon thus lifting it off the ground.
That will depend on the size of the bomb, how far above ground it explodes, and how far away it is from you.
it all depends on the speed that the bullet is shot at. other contributing factors include the angle of the shot and the distance from the ground that the bullet is shot at. sadly, the x-factor of this question is that the ground determines how far it will ricochet. if the ground is water, it will not ricochet.
I hope u know this is in a 5th grade science book
Yes, this helps them to hear far off horses or buffalo.
