Which is Earth's largest source of drinkable water?

• lakes

• rivers

• oceans

• aquifers

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
