Some power plants pump water down deep holes into hot rock. The hot rock heats the water, which turns the water into steam. The steam rushes back to Earth’s surface and is used to make electricity. This plant is generating which alternative energy resource?

biomass

geothermal energy

solar energy

wind energy

Which of the following would be an example of an ecosystem change caused by humans?

A beaver builds a dam and blocks a stream, forming a pond. Organisms that rely on fast moving water die out. Over time, populations of pond-loving species increase in the area.

Salvinia, a rootless, aquatic fern, floats on a lake surface forming dense mats. Some attaches to a boat. The boater takes his rig to another lake without removing the plant first.

When a volcano erupts, the surrounding plants are destroyed and leave only bare lava. Pioneer species begin to grow on the lava. Over time, more and more different species reclaim this area.

A herd of grazing buffalo tramples on tree seedlings and digs up the ground, destroying the young trees. In the bare patches, new plants grow.

Fishermen have harvested certain fish to the point where the population of that fish is decreasing. What could this level of direct harvesting cause?

ecosystems to be improved for future generations

all other fish species to increase in number

the restoration of ecosystem stability

ecosystems to be severely damaged

Often times a developers often will create a “green space” after he/she has developed a subdivision. A green space is an area with trees and grass to provide an alternate to the trees that were removed. What happens to the birds if the developer does not create the green space?

loss of habitat

increase in available food

An increase in the amount of nutrients in water is called eutrophication. The extra nutrients causes the fast growth of algae on the water’s surface. What causes this overgrowth of algae?

oil spills

increase in production of acid rain

wastewater and fertilizer runoff getting into waterways

gases formed by burning fossil fuels mix with water in the air

How does overuse of a resource impact the environment?

If a resource is depleted (all used up), it can be made again easily, so it does not impact the environment at all.

If a resource is depleted (all used up), it can cause animals to starve and go extinct.

If a resource is depleted (all used up), something else can be used in its place, so it does not impact the environment at all.

If a resources is depleted (all used up), it doesn't matter, so it does not impact the environment at all.

How do you prove that humans are having a negative impact on Earth? What data shows that?

Showing an increase of animals moving to an area.

Showing the positive things that have occurred due to human activity.

Showing an increase in number of species extinct after deforestation occurring.

Showing an increase in tourism to a certain region, the previously had little.

What happens when waste is dumped into water?

Waste acts like a fertilizer, promoting growth of bacteria and algae.

Waste acts like a poison to plants in the water.

Waste raises the temperature of water.

Waste lowers the pH of water.

The population of the Black Sparrow hawk is decreasing (going down) in Cape Town, South Africa. During the same time period, urbanization (building of houses and cities) in the Cape Town has increased. What data would best support the claim that the urbanization of forests around Cape Town is likely the cause of the decline of the Black Sparrow hawk population?

The houses built in the urbanized area are eco-friendly.

The Black Sparrow hawk is a favorite found in zoos in the area.

The population of the Black Sparrowhawk remained constant (the same) until the urbanization of the areas around Cape Town began.

The area around Cape Town that was urbanized is not a known habitat for the Black Sparrow hawk.

Pollution can enter the hydrosphere in many different ways. Point-source pollution is a type of pollution that comes from a single, identifiable source. Which statement describes a type of point-source pollution?

Oil being transported on a ship spills into the ocean.

Litter along beaches gets pulled into the ocean by the tide.

Grease from cars washes into a stream along the roadway.

It pollutes nearby soil when animals track mud from one place to another.

It pollutes water when runoff carries chemicals from the soil to local streams and lakes.

It causes drinking water in the homes when chemicals seep into underground pipes.

It pollutes the air above the location when chemicals break down and produce gases.
