If you ask a scientist what the boiling point of water is, they would tell you this temperature.

Water vapor forms clouds, fog, and dew through this process.

At a spring, the Earth's surface intersects with this line that measures the top level of an aquifer.

These reservoirs made of porous rock store filtered water underground.

Water with a low this level is considered acidic.

Water's polarity makes it excellent at breaking down most substances, giving water this nickname.

Snow and hail are frozen forms of this.

In order to store water, an aquifer must have these two "P" properties.

These structures are where most of Earth's freshwater is stored.

Transparency is how clear water is, the cloudiness of water is also called this other "T" word.

Hydrogen bonds between neighboring water molecules give them this property

Water stored in glaciers may enter the atmosphere directly through this process.

This is the process by which an aquifer is replenished with water.

This mixture of salt and freshwater is typically found in estuaries.

Water that is safe to drink is known by this adjective.

While water is changing state of matter, its temperature stays the same as it absorbs or releases energy in this form.

Humans release water from our skin through perspiration. When plants release water through their leaves, it's called this.

Overuse of coastal aquifers can result in this process as saltwater replaces freshwater.

A river basin is an example of one of these areas of land that drains into a water source.

This type of pollution comes from a single identifiable source.

Water is able to defy gravity as it climbs up plant stems through this type of action.

Surface water becomes groundwater through this process. How sneaky!

San Joaquin Valley suffered from this as its aquifer was depleted, causing the land to sink about a dozen yards.

This is the point where a tributary meets another river.

This type of flowing aquatic habitat is associated with low transparency and high dissolved oxygen.
