Approximately 97.5% of the Earth's water is oceanic saltwater. The distribution of freshwater on Earth is depicted in the pie chart. What can be inferred about the MAJORITY of Earth's Freshwater?

• Most of it is readily accessible and usable.

• Most of the freshwater is a habitat for flora and fauna.

• It is mostly underground, requiring us to drill wells to access it.

• Most of it is unusable as it is in a frozen state.

A diagram is drawn by a student to illustrate the stages of the water cycle. Which stage is associated with the creation of clouds?

• condensation

• evaporation

• freezing

• melting

S6E3.b

When evaporated water comes back to the earth, it is known as...

• condensation

• sublimation

• precipitation

• transpiration

S6E3.b

What would happen to the water cycle if there was no heat from the sun?

• It would speed up

• It would stop

• It would remain unaffected

• It would reverse

The process by which water is absorbed by the root system of plants, moves up through the plant, and is released to the atmosphere as water vapor is known as?

• evaporation

• sublimation

• transpiration

• infiltration

Explain the impact of temperature fluctuations on the formation of clouds.

• When water on Earth cools, it condenses in the air, leading to cloud formation.

• When water on Earth cools, it evaporates into the atmosphere, leading to cloud formation.

• Water on Earth warms up and evaporates into the atmosphere. It then cools and condenses, resulting in cloud formation.

• Water on Earth warms up and evaporates into the atmosphere. There, the water vapor continues to heat up, resulting in cloud formation.
