How do clouds and rain form over the US?

Answer:
evaporation form the ocean
Answer:
The hydrological cycle puts water into the atmosphere from oceans, lakes, rivers, evapotranspiration and other sources.

The water is a gas in the atmosphere at a given temperature and pressure. When the temperature cools the water starts to condense around any handy dust particle.
The water droplets collide and/or accept more condensation until they get too heavy to remain aloft on updrafts and air currents they fall as rain.

In colder conditions the water vapour forms snow, sleet or hail.
