Scientists observed a rocky, rotating object orbiting in space. It was 250 km wide. The rocky object was located several times farther away from the Sun than the Earth. The object is most likely —

• Venus
• the Moon
• Mars
• an asteroid

The Moon travels in an elliptical orbit that is nearly circular around the Earth. This pattern has occurred for millions of years. Which of the following best explains the cause of the Moon’s motion?

• The Moon is acted upon by balanced forces, so the orbit maintains the same nearly circular shape.
• The gravitational forces from the Sun and the Earth on the Moon are equal, causing the Moon to maintain its orbit.
• The Moon is constantly affected by the unbalanced force of the Earth’s gravity which causes it to continue to orbit the Earth.
• There was a gravitational force millions of years ago that pulled the Moon in an elliptical direction and the Moon has not since been acted upon by a force.

How do fossil records support the theory of plate tectonics?

• Similar fossils are found on the same continent at different time periods.
• Similar fossils are found on various modern continents.
• Different fossils are found on the same continent during the same time period.
• Fossils found along coastal regions of modern continents are unique.

How does clearcutting or deforestation near a watershed affect the quality of the water?

• The surface water will not be affected.
• The surface water will be purified.
• The surface water will become cleaner.
• The surface water will become less clean.

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 animals that live in or near the lake will add pollution to 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 protect the lake because the high elevation of the water table will block pollution from entering the lake.

Some areas of an ocean are known as dead zones. These zones form when excess organic material decomposes. This increased decomposition uses up the oxygen from the water. Which human activity is most affected by the increasing number of dead zones in the ocean?

• Offshore oil drilling, because water in dead zones is toxic
• Commercial fishing, because fish cannot survive without oxygen
• Commercial shipping, because dead zones change the course of ocean currents
• Sand mining, because oxygen is not available to form the sands on ocean beaches

Climate change can increase ocean temperature and make ocean water more acidic, both of which affect coral reefs. The table shows the conservation status of coral reefs around the world.

• Most coral reefs are thriving
• Coral reefs are being affected by climate change.
• Few conservation programs exist to help save coral reefs.
• Coral reefs that are not currently affected by climate change will not be affected in the future.
