Watershed Review

Pollution from human activity often ends up in lakes and oceans due to watersheds. Which part of the diagram is most responsible for this movement? Select the correct answer.

• Precipitation

• Condensation

• Runoff

• Evaporation

• Lake

Farmers can best reduce negative effects on the water quality of nearby streams and lakes by planting crops that —

• produce less oxygen

• produce less carbon dioxide

• need less fertilizer

• need less solar energy

The model shows an area near a lake. Community leaders are planning new laws to help protect the lake from pollution. One proposed law will make it illegal to dump trash on the shore of the lake, but the law still allows trash to be placed in the area labeled “Flow-through wetland.” Which statement about the proposed law is supported by the model?

• The proposed law will protect the lake because plant roots between the wetland and the lake will stop pollution from entering the lake.

• The proposed law will not protect the lake because groundwater will carry pollution from the wetland directly into the lake.

• The proposed law will not protect the lake because animals that live in or near the lake will add pollution to the lake.

• The proposed law will protect the lake because the high elevation of the water table will block pollution from entering the lake.

How does the agricultural activity most likely affect the surface water of the area?

• Excess crop fertilizer is carried by runoff into the river, causing excess growth of water plants.

• Excess crop material accumulates on the riverbanks, slowing the movement of the river water

• Crops reduce erosion, increasing the amount of soil entering the river.

• Crops absorb pure water from soil, causing the remaining water to contain more salt.

The picture below models runoff from a mine into local watersheds. The runoff will affect local watersheds in all of the following ways EXCEPT —

• by contaminating the lake with heavy metals.

• by increasing sediments in the stream.

• by increasing the number of animals that live in the lake or stream.

• by introducing acid rock drainage to the lake and stream.

All of the following are reasons for protecting watersheds except—

• They provide drinking water.

• They promote pollution

• They sustain wild life

• They provide recreation

A company known as Arten Industries is wanting to build a factory in the watershed that is pictured. The company wants to limit the ecological impact it has on surrounding areas. What would be the worst location for the factory?

• At the top of the river.

• Away from the river.

• At the middle of the river.

• At the bottom of the river.

As the map shows, there are multiple drainage basins in Texas. Ft. Worth and Dallas are in the same drainage basin. What is the most likely reason that the water in the Trinity River is dirtier in Houston than it is in Dallas?

• Ocean pollutants are entering the river.

• Pollutants are entering from other drainage basins.

• The river basin picks up more human pollutants.

• The water goes through a salt dome and get more polluted.
