Water Cycle Interactions

When liquid water in the ocean evaporates, it changes its state of matter and becomes -

• Water droplets

• Water vapor

• Clouds

• Water dioxide

Molecules of water vapor change their state of matter and become liquid water molecules when -

• They are heated up

• They touch other molecules of water vapor

• They cool down

Condensation occurs in the water cycle when -

• Water vapor in the atmosphere cools down and becomes a liquid

• Thermal energy from the Sun heats liquid water and it becomes a gas

In the water cycle, water vapor condenses into liquid water molecules and forms clouds.

What are TWO events that would cause this?

• Warm, humid air rises high into the atmosphere and gets colder

• Heat from the Sun warms the surface layer of ocean water

• A cold air mass (cold front) meets with a mass of warm, humid air

As more and more water molecules collect together in clouds, they form -

• Large and small pieces of hail

• Small water droplets

• Wind gusts that travel hundreds of miles

• Grains of grey and black dirt

Precipitation occurs when -

• Clouds get too heavy and fall down

• Water droplets in clouds get too heavy and fall

• Water vapor changes into liquid water molecules

Warm ocean water is carried by ocean currents to many different parts of the world, which causes certain areas to experience -

• Warmer temperatures and more precipitation

• Cooler temperatures and less precipitation

• Longer winters with more snow and sleet
