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

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

• because it forms where fresh and saltwater meet

• because it receives water directly from precipitation

• because it rises to the surface near the ocean

Which best describes the process of transpiration in the water cycle?

• water lost by plants enters the atmosphere as water vapor

• Water from the ocean enters the atmosphere as water vapor

• Water on the surface of Earth returns to the surface as liquid water

• Water on the surface of the Earth enters the groundwater supply
