Question 9(Multiple Choice Worth 3 points)

The two images of the McCall Glacier in Alaska depict how it has changed in size over the past 50 years.

These two photographs of the McCall Glacier in Alaska were taken from the same location in 1958 and 2003. The 2003 image shows how far the glacier has receded since 1958.

Predict how the change in this glacier will impact marine ecosystems.

It will increase ocean temperatures due to cold water being added.
It will increase sea level due to runoff from the melting ice.
It will increase temperatures on land due to a lack of snow cover.
It will increase the amount of carbon stored in the oceans.

(02.01 MC)

Wegener’s theory of continental drift was largely dismissed by the mid-1900s. What new evidence was able to revive this theory, and why?

Continental ridges were found, suggesting that parts of the land used to be below sea level.
Sonar technology found mid-ocean ridges, where new ocean floor was being created.
The coastlines of South America and Africa were similar in shape, suggesting that they shared a common tectonic plate.
The mantle moves through radiation, suggesting that rock in the Earth is not solid.

When a crustal plate is forced below another plate
When a crustal plate fuses with another plate

The outside-in model states that most of Earth's water came from meteorites or comets. What evidence would support this model?

Finding multiple comets in our solar system that contain water
Observing that a single volcanic eruption increased water vapor levels
Multiple observations of water bonded to minerals in Earth's mantle
Finding that water extracted from a single comet is not similar to ocean water
Question 20(Multiple Choice Worth 3 points)
(02.02 HC)

Scientists have found that Mars has water ice at its poles, even though volcanic activity has never been observed on Mars. Would this prevent the inside-out model from becoming a theory?

Yes, because any comet that hit Earth also hit Mars.
Yes, because it shows that volcanic activity is necessary for a planet to have liquid water.
No, because no data from Mars is applicable to Earth.
No, because a single observation is not sufficient to discredit a theory.
Question 21(Multiple Choice Worth 3 points)
