Water Cycle (ESS.8)

What are some ways water moves on Earth’s surface?

• rivers

• oceans

• streams

• lakes

The process by which water changes from a liquid to a gas or vapor is called?

• condensation

• evaporation

• water droplets

• gravity

How do plants contribute to the water cycle?

• Water travels from the soil, through the plant, and evaporates into the atmosphere.

• Water vapor in the air loses heat or thermal energy and produces water.

• The leaves of the plants form water droplets that evaporate into the air.

The force of attraction between two objects because of their masses is called?

• groundwater

• sun energy

• gravity

• condensation

How do snowflakes form?

• They form in cold temperatures when water begins to crystallize into ice. They continue to grow bigger until they eventually fall to Earth.

• They form as a result of a chemical reaction.

• They form when plants release carbon dioxide into the atmosphere.

How does the Sun's energy contribute to the movement of the water in the water cycle?

• The Sun's energy makes the water produce condensation therefore making more water.

• The Sun's energy causes more rainfall.

• The Sun's energy heats the water, causing the water to evaporate into a gas called water vapor.

How can the water molecules you drink today be millions of years old?

• Water molecules have been continuously cycling on Earth for millions of years through evaporation, precipitation, and condensation.

• The water is cleaned and purified by people then reused.

• The water we drink is not millions of years old.

The process of water being released from clouds in the form of rain, hail, or snow is called?

• water vapor

• precipitation

• gravity

• evaporation

The process by which solids form is called?

• crystallization

• sun energy

• water droplets

• precipitation
