Question

Which of the following examples best represents a geographic study on a large scale?

a. The effects of global warming on the frequency of brush fires in Australia.
b. The effects of rising ocean levels on marine ecosystems.
c. The impact of introduced species on the native species of Australia.
d. The erosion of the North Carolina coastline.

Answer 1

Answer: The answer is D

Explanation:Because the rest of the answers are on a small scale.

Answer 2

A study on a large scale should have a bigger focus than just one country, or even one continent. Because of this, a study focusing only on Australia (answers a and c) are not good examplef for large-scale studies and neither is one focusing on North Carolina (answer d).

The correct answer is
b. The effects of rising ocean levels on marine ecosystems.
