To say clouds defy gravity would be misleading, as they do not defy gravity. However rising air currents keep the clouds in the air. The air currents are stronger than the rate at which gravity makes the rain fall (which is not that fast). Clouds are so light, that even the smallest upward air current can make a clouds stay up. Rain falling is basically when the mass of the drops exceed the air currents.
It is impossible to actually "defy" gravity. Even the Voyager spacecraft at over four billion miles from the earth experience some gravity from the earth. Satellites can orbit the earth at as low as 220 miles or less. They still fall toward the earth, but their forward speed carries them at an arc that matches the earth's surface.
It is gravity.
Yes. Stars form when clouds of gas and dust, called nebulae, collapse under the force of gravity.
It's close to the ground because gravity is pushing it down.
Because not all clouds produce rain ! The water droplets inside a cloud need to be a minimum size to succumb to gravity and fall as rain.
It doesn't, nothing can defy gravity.
No
The plural of defy is defies. As in "this defies the laws of gravity".
The chemical that is called defying gravity.
Ultimately, no.
No they don't.
adhesion.
They cannot.
The water seemed to defy gravity.
No, they don't.
No.
