The Water Cycle and Weather Mr. Leslie’s Science Class

Three States of Water ¾ of Earth’s surface is covered by water. Water is found on Earth in three forms: Solid Liquid Gas

Streams Lakes Rivers

Water vapor (you cannot see it)

Evaporation Evaporation is the change of state from liquid to gas Even on a cold day, heat from the Sun can make some water from a lake evaporate.

Condensation Condensation is the change of state from gas to liquid. When water vapor, is in the air, connects with cool air, the water vapor condenses back to liquid form.

Water Cycle The water cycle is the movement of water into the air as water vapor and back to Earth’s surface as precipitation.

Precipitation Is any form of water that falls from clouds to Earth’s surface Sleet or

Types of Clouds Stratus Cumulus Cirrus Cumulonimbus Cloud Website - NASANASA

Stratus Clouds Stratus clouds are low-level clouds that form in layers. Stratus clouds usually bring rain.

Cumulus Clouds Cumulus clouds are fluffy and have flat bases. They form low in the sky. They usually mean fair/good weather. They look like animals!!!

Cirrus Clouds Cirrus clouds are thin, feathery clouds made of ice crystals. They form high in the sky. Cirrus clouds indicate fair/good weather.

Cumulonimbus Clouds Cumulonimbus clouds are normally the tallest clouds and bring thunderstorms.

Questions to answer Tall clouds that produce thunderstorms are called? What are the four types of precipitation? What are the stages of the Water Cycle? What is happening when you glass of water has drops of water running down the outside of your glass? What are the three states of water?
