Answer: Mountains would be mountains
Explanation:
Mountains wouldn't not be mountains. If the world was flat, then that would necessarily mean that the tectonic plates won't shift or rub up against each other.
The correct answer is - (1) rising expanding cooling condensation.
At first there's the evaporation of water, since the water vapor is less dense than the air it rises up and starts to expend as it goes further upwards in the atmosphere. Once it reaches the upper layers of the troposphere than the cooling process starts because the temperature is decreasing with the altitude. Because of the cooling the process of condensation will start taking place and thus the formation of clouds were the water vapor returns to liquid form and creates rain. The cycle repeats its self all the time.
