Question

1 mark for review which of the following best explains the potential impact of rising global temperatures on agricultural regions? a the wheat belt will shift northward. b mediterranean agriculture will expand southward. c polar regions will dry out, making cultivation impossible. d nomadic herding will end as conditions become too harsh. e centers of market gardening will shift to the arctic circle.

Explanation:

To determine the correct answer, we analyze each option:

• Option A: Rising global temperatures make higher latitudes (northward for Northern Hemisphere wheat belts) more suitable for wheat cultivation as warmer temperatures expand the viable growing zone. This is consistent with climate change impacts on agriculture.
• Option B: Mediterranean agriculture thrives in warm, dry summers and mild winters. Rising temperatures would likely make southern regions (closer to equator) too hot/dry, so it would expand northward, not southward. Eliminate B.
• Option C: Polar regions are cold and icy, not dry. Rising temps might melt ice, but dryness isn’t their main issue, and cultivation is already limited there. Eliminate C.
• Option D: Nomadic herding is adapted to arid/semi - arid regions. While climate change affects them, saying it will “end” is extreme. Eliminate D.
• Option E: The Arctic Circle is extremely cold; even with warming, it’s unlikely to become a market gardening center (which needs moderate temps and access to markets). Eliminate E.

Answer:

A. The wheat belt will shift northward.
