Hydrosphere

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
• it receives water directly from precipitation
• it rises to the surface near the ocean
• pollutants are filtered by rock and soil deep within earth

Where does most fresh water exist?

• ice caps, lakes, and streams
• glaciers, rivers, and oceans
• aquifers, ice caps, and glaciers

• evaporation
• precipitation
• condensation
• transpiration

After the rain falls down onto Earth's surface, what most likely happens? What is it called?

• 1. The remains of the water is soaked into the ground.
  2.Groundwater
• 1. Groundwater
  2. The remains of the water is soaked into the ground.
• 1. Groundwater
  2. Transpiration happens to the plants.
• 1. The liquid turns into an gas or an water vapor
  2. Evaporation

What is it called when plants give off water vapor as a waste product?
