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 the Earth

A local farm experiences significant drought over a 2-year period. A temporary solution for the lack of water is to dig another well closer to the fields to water crops. Two years before, in a similar situation, the water table was reached at 15 feet below the ground. Which is necessary for the well to supply water to the crops?

• The well needs to be dug to 13.5 feet

• It is not necessary to find the water table when digging a well.

• The well should be dug to more than 15 feet to find the water table.

Which best describes why melting icebergs to obtain freshwater can be harmful to our environment?

• It can increase the habitats of arctic animals.

• It can be costly and complicated to transport the icebergs.

• It can cause temperature change in water and climate change in a region.

Rivers and streams transport nutrients, salts, sediments, and pollutants. Which is the correct order for this process?

• estuaries -> oceans -> watersheds

• watersheds -> oceans -> estuaries

• watersheds -> estuaries -> oceans

If water is recycled in the atmosphere, which best describes why water availability on Earth is decreasing?

• An increase in droughts is slowly reducing freshwater reservoirs.

• Due to an increase in Earth's temperature, evaporation rates continue to increase reducing liquid water on the surface.

• Earth's freshwater continues to become more polluted, reducing the supply of freshwater safe for humans to consume.
