Freshwater is water that contains very little salt and is drinkable for humans and wildlife. Freshwater is found in rivers, lakes, streams, water wells, aquifers, waterfalls, and icebergs as well as snow and the polar ice caps. An aquifer is an underground area that is permeable and contains water.

2. Surface Water
• Surface water is the water that
remains on Earth’s surface and is
visible as streams, rivers, oceans,
etc.

3. Ground Water
Ground water is water that enters the
ground from precipitation or runoff through
the process of infiltration.

4. River Basin
• A river basin is the area
surrounding a river and its tributaries
that drain into that river.

5. Aquifer • An aquifer is an underground area that is permeable and

7. Saltwater
• Saltwater is water that contains a higher level of salts, such as
the oceans and certain lakes, such as The Dead Sea and in Utah,
The Great Salt Lake.

8. Estuary
• An estuary is an area where freshwater from rivers flows into saltwater from the ocean. The mixed water is called
brackish because it has more salt than river water but less salt than ocean water.

9. Ocean Currents
• Ocean currents are not ocean waves. Ocean currents are
the movement of ocean water in streams from one area to
another. Sea water within the current is moving faster than
surrounding ocean water. It may also have a different level of
salinity and a different temperature. The Gulf Stream is one
ocean current.

10. Watershed
• A watershed is an area of land that catches and moves all of
the precipitation that falls on it (this precipitation then flows
toward a river, stream, lake, or the ocean. Much of the
precipitation is absorbed by the ground (infiltration) in the
watershed and goes down to become part of the groundwater.

11. Freshwater Spring
• A spring is a water source that is bubbling up from
an underground source such as an aquifer. The spring
may have enough water flowing to create a pond, a
lake, or a stream.

12. Salinity
• Salinity refers to the amount of salt
that is in a body of water. Seawater is
saturated with dissolved salts, so it has
a higher salinity than brackish water in
an estuary.

13. Brackish Water
• Brackish water is water having more salinity than freshwater, but
not as much as seawater. It may result from mixing seawater with
fresh water together, as in estuaries, or it may occur in brackish fossil
aquifers.

14. Floodplain • A floodplain is the area around a river that is often flooded as
water in the river rises.

15. Infiltration
Infiltration is the process by
which water on the ground
surface enters the soil and
rock material under the
surface of the ground.
