liquid.

Answer

take in heat energy from the Sun and turn into

ice.

Answer

give off heat energy to the Sun and turn into a

surface into the atmosphere and back to Earth's

surface again

Answer

to show how severe weather forms in the water

cycle

Answer

to show how Earth's water formed billions of
