Why is water from an aquifer more likely to be cleaner than water from

other sources?

• because it forms where fresh and salt water meet

• because it receives water directly from precipitation

• because it rises to the surface near the ocean

• because pollutants are filtered by rock and soil deep within Earth

Pamlico Sound is an estuary, a body of water in which freshwater from a river meets and

mixes with saltwater from the ocean. The sound’s salt water comes from the Atlantic Ocean.

The Neuse River Basin contributes freshwater to the sound but is not the only source.

Freshwater from the Tar-Pamlico Basin also flows into Pamlico Sound.

The water located in the Pamlico Sound is called?

• salt water

• brackish water

• fresh water

• universal water

Which is Earth’s largest source of drinkable water?

• lakes

• rivers

• oceans

• aquifers

• groundwater and aquifers

• swamps and wetlands

• ice caps and glaciers

• akes and rivers

• The most dense water is cold water and the least dense water is

  frozen.

• The most dense water is cold water and the least dense water is

  warm water.

Because of water’s polarity, it

• cannot dissolve anything containing water.

• cannot act as a solvent.

• is the universal solvent.

• is able to only partially dissolve materials.

Which property of water allows an insect to skim lightly across the surface of a pond?

• high specific heat

• ability to dissolve many substances

• surface tension

• lower density as a solid than as a liquid

Which best explains why freshwater is in such short supply?

• Most of the freshwater is frozen in ice sheets.

• Most of the freshwater is trapped underground.

• Most of the freshwater is cycling in the atmosphere.

• specific heat
