How does water vapor contribute to the formation of clouds?

• a. Water vapor absorbs heat from the sun and condenses into clouds.

What is the purpose of this model?

• to illustrate how water travels from Earth's

  surface into the atmosphere and back to Earth's

  surface again

• to illustrate how some water is lost on Earth as

  some of it never returns to Earth's surface once

  it evaporates

• to show how severe weather forms in the water

  cycle

• to show how Earth's water formed billions of

  years ago
