2

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?

2

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

2

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

2

Which of the following means of transportation uses a renewable resource for its energy source?

2

Deforestation in Brazil is impacting animals that live in that area. Which of the following describes how animals are being negatively impacted?

2

Which of the following shows only abiotic factors that could affect the stability of an ecosystem?

2

Use the chart to answer the question.
What percentage of our energy use comes from fossil fuels?

2

Which of the methods of generating electricity does NOT use alternative energy resources?

2

A NEMS Student notices that new houses are being built across the street in the Eagle Point Neighborhood. The first thing the builders do is remove all of the trees. Which of the following effects would result from this action?

2

Which of the following helps protect species from extinction?

2

Which is a major environmental concern for our oceans?

2

A device is developed that collects trash found in the ocean. To evaluate the effectiveness of this device, what data would need to be collected?

2

The class brainstormed nonrenewable resources. Which list is correct?

2

Which alternative energy source does this information describe?

2

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?

2

Students decide to create a garden in a once vacant filled with trash. They collected the trash, recycled the glass and plastic they found, as well as any paper. Which observation is the best evidence that they have made a positive effect on the Earth?

2

What is the best reason for using renewable resources?

2

Based on the data collected, which source of alternative energy is most efficient?

2

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?

2

How does overuse of a resource impact the environment?

2

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

2

What happens when waste is dumped into water?

2

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?
