This science document discusses precipitation. It defines precipitation as water that falls to Earth's surface, occurring when water vapor condenses into liquid or solid form. The water can fall as rain, snow, sleet, or hail as water droplets in clouds collide and stick together, growing too large to remain airborne. Precipitation collects in bodies of water, soaks into the ground as groundwater, or falls back into oceans as part of the water cycle.

3. Precipitation
Precipitation is the water that falls to Earth´s surface. For precipitation to occur,
water vapor must condense (it must change into a liquid or solid).
This water can fall as rain, snow, sleet, or hail.
In the cloud, some water drops bump into others and stick together. The drops
get bigger. When they get too large to stay up in the air, they fall to Earth as
rain, snow, sleet, or hail.
Some of this precipitation collects in lakes, rivers, and other bodies of water.
Some precipitation soaks into the ground to become groundwater. Some falls
directly back into the ocean.
