Lesson 3 Exploration 3 Water Cycle

Describing the Movement of Water in Earth's Atmosphere

Multiple Choice

What evidence of water in the atmosphere can you see in the photo?

• clouds

• sun

• beach

• ocean

Multiple Choice

How do you know evaporation has happened in this model of the Water Cycle?

• you can see the green grass behind the cotton balls

• you can see the "cloud" above the cotton balls

How Water Reaches the Atmosphere

When solid water changes directly to water vapor without first becoming a liquid. This is called sublimation.

Multiple Choice

Is energy gained or lost for Sublimation to occur.

• energy is gained

• energy is lost

Transpiration

As water flows throughout a plant, some water changes to water vapor as it leaves the plant through small openings called stomata.

Multiple Choice

In order for a plant to release water vapor through its leaves, the water will need to...

• gain energy

• lose energy

Evaporation

When liquid water gains enough energy to escape the liquid's surface and form water vapor.

Multiple Choice

When water evaporates, it...

• gains energy

• loses energy

Multiple Choice

Where does most of the water in the atmosphere come from due to evaporation?

• sublimation

• trasnpiration

• oceans

Water in the Atmosphere

When water molecules collide they can gain and lose energy. If a water molecule collides with a molecule that is warmer, the water molecule will gain energy. If it collides with a molecule that is cooler, it will lose energy.

Multiple Choice

True or False: If a water molecule collides with a warmer water molecule, it will cause the water molecule to...

• gain energy

• lose energy

Condensation and Clouds

As air cools, water vapor in the air may change to liquid water. The process of a gas becoming a liquid is called condensation.

Multiple Choice

The process of a gas becoming a liquid...

• energy is gained

• energy is lost

Precipitation

As water droplets in clouds become larger and larger, gravity pulls the water droplets toward Earth's surface. Precipitation is any form of water that falls to Earth from clouds.

Multiple Choice

What are the 4 types of precipitation?

• rain, snow, sleet & lightning

• rain, snow, thunder & hail

• rain, snow, sleet & hail

Deposition

Deposition occurs when water vapor changes state directly from a gas to a solid. Deposition is the reverse of sublimation.

Multiple Choice

Deposition is the reverse of:

• precipitation

• sublimation

• transpiration
