The processes and mechanisms that drive the water cycle are the same processes that helped form the oceans long ago. When Earth first formed, it was extremely hot. But as it began to cool, so did the water vapor in its atmosphere. Which processes in the water cycle are most likely responsible for turning the gaseous water vapor in the atmosphere into liquid water that eventually reached Earth’s surface? HELP!

it's when something is going so fast it makes a loud noise, breaking the sound barrier, for example: a jet makes a loud noise, not only cause of the jet but because they reached a point where they went so fast that you can year the noise from various parts, kinda like a police car, lets say the car was going   so fast that you hear the siren of the cop car right next to you, but the car is probably a mile a way, it's cos the siren was next to you a few seconds if you understand me
