Which of the following is an example of how humans positively impact surface water and ground water?

• Excess nutrients from fertilizer enters a stream and increases the population of algae.

• Pesticides travel through the ground and contaminate water in aquifers.

• Rivers are dammed to create reservoirs causing some rivers to dry out before reaching the ocean.

• Excess fertilizer enters lakes creating an additional food source for fish populations.

A watershed is the land that water flows across or through on its way to a stream, lake, wetland, or other body of water. How do scientists recommend preserving a watershed?

• create lakes by damming up rivers in the watershed

• encourage agricultural usage in the watershed

• preserve forests and wetlands within the watershed

• increase construction within the watershed

Pablo is building a miniature watershed model of his city out of clay. He wants to see where rainwater carries spilled motor oil from the city's streets. Pablo plans to make all of the hills, buildings, and streets in his model out of clay. He then plans to spray water on the model to see where it flows when it rains. What could Pablo do to help him track where rain water carries spilled motor oil?

• He could use hot cocoa powder to represent the oil.

• He could use sand instead of clay.

• He could use maple syrup instead of water.

• He could use peanut butter to represent the oil.

Many home cleaning products contain phosphates. If wastewater containing excess phosphates drains into a pond, the phosphates encourage the growth of algae. How might this change in a pond's ecosystem affect the quality of life for other living things in the pond?

• Some algae produce toxins, so the water could be poisoned.

• Other water plants might have less light to help them grow.

• Fish, like carp, that eat algae will have more food.

• all of these

A single gallon of motor oil is able to contaminate 1 million gallons of freshwater. Considering this, why is it important for every individual in a community to practice good stewardship of the environment?

• There are many man-made chemicals that are dangerous to human health.

• Water is a nonrenewable resource.

• Most people living in a community ride in vehicles that use motor oil.

• A single person's actions can affect the health of the whole environment.
