Bald eagles live along coastlines and fly down to the water to capture fish which make up a significant part of their diets.  Osprey also rely upon fish for their diets. 

Describe the relationships between bald eagles, fish, and osprey. Options: Bald eagles are competitors of fish and parasites of osprey; Bald eagles are competitors of fish and predators of osprey; Bald eagles are parasites of fish and competitors of osprey; Bald eagles are predators of fish and competitors of osprey.

Which statement correctly matches the hemisphere, season, and Earth's position relative to the Sun?

The Northern Hemisphere experiences summer when it is pointed towards the Sun.

The Northern Hemisphere experiences spring when it is pointed away from the Sun.

The Southern Hemisphere experiences winter when it is pointed towards the Sun.

The Southern Hemisphere experiences fall when it is pointed towards the Sun.

Using both the chart and the diagram, Amelia concluded that ice floats because it is less dense than water. Which statement provides a logical defense for Amelia's conclusion?

Back

When water becomes ice, its molecules spread farther apart, forming an open network with empty spaces.

Front

Which activity is most likely to cause an increase in Earth’s surface temperature?

Back

Burning fossil fuels, because this activity releases greenhouse gases.

Impact of capturing tertiary consumers like tuna and grouper on ocean ecosystem?

Back

Smaller fish become more abundant and the food chain balance is disrupted.

Why are human-caused changes like overfishing and habitat change potentially dangerous to many marine species?

Back

These changes occur faster than many organisms can adapt.

The diagram below shows a model of Earth and the Sun during a specific season in the Southern Hemisphere. Which season is represented in the Southern Hemisphere by the positions of Earth and the Sun?

Back

Summer, because the Southern Hemisphere is tilted toward the Sun
