Question

how are the pacific’s low islands distinct from the high islands? a. the low islands were formed from volcanoes rising above the ocean surface. b. the low islands have rich volcanic soils. c. the low islands have lush rainforests. d. the low islands often have no sources of freshwater. please select the best answer from the choices provided.
a
b
c
d

Explanation:

• Option A: High islands (formed by volcanic activity) have volcano - formed features, while low islands (like atolls, formed from coral reefs around sunken volcanoes) are not formed from volcanoes rising above the ocean surface. So A is incorrect.
• Option B: Rich volcanic soils are a characteristic of high islands (due to volcanic origin), not low islands. Low islands have coral - derived soils which are not as fertile. So B is incorrect.
• Option C: Lush rainforests are more common in high islands with more rainfall - retaining features and better soil. Low islands, with their small size and coral - based structure, do not typically have lush rainforests. So C is incorrect.
• Option D: Low islands (such as atolls) often have no natural sources of freshwater as they are small, made of coral, and have limited ability to retain or collect freshwater. High islands, with their larger size and more complex geology, are more likely to have freshwater sources like rivers and aquifers. So D is correct.

Answer:

D. The low islands often have no sources of freshwater.
