The includes all the gases around Earth.

• hydrosphere

• crust

• atmosphere
• cloud

Which statement describes how clouds form?

• Water vapor in the atmosphere freezes and then thaws at lower altitudes.

• Water vapor in the atmosphere condenses around tiny particles of dust.

• Snow from the surface of Earth hangs in the air.

• Gases such as nitrogen and helium, combust in the atmosphere.

Where does water go when water evaporates?

• It goes into a nearby river or stream.

• It sinks into the street.

• It rises into the atmosphere.

• It goes into outer space.

Why should we conserve freshwater?

• Because it is good

• Earth’s water supply is growing larger.

• Once we use all of Earth’s freshwater, it is gone forever.

• A small percentage of Earth’s water is freshwater, and everyone needs it.

All water on Earth is recycled through .

• the water cycle
• pockets of nitrogen

• exhaled gas

• dead organic material

Identify the statement that best describes where Earth's freshwater can be found.

• Most is trapped in glaciers and ice caps.

• Earth's freshwater is spread out equally over ice, groundwater, and surface water.

• Most of the freshwater on Earth is found underground. The rest is stored as surface water.

• Earth's freshwater is found mostly in rivers and streams. Very little is found in glaciers or ice caps.
