Condensation

Look at the picture. Explain how the ocean interacts with the air to eventually bring rain to fall over the house. Draw a picture to help explain your thinking.
The ocean gets heated by the sun which causes water vapor to rise into the atmosphere (air). As the water vapor rises, it cools and condenses to form clouds.

What is the process called in which clouds release moisture allowing it to fall to the ground.
Precipitation

What is the name for precipitation that runs off the landscape into the ground or back into the surface water that it came from?
Runoff

If the ocean temperature stays the same but the air in atmosphere above the ocean becomes very cold, do you think it will rain more or rain less?
It will rain more because the cold air is leading to more condensation happening.
