Question 1

Multiple choiceEasy1 mark

A terrestrial region has high temperatures throughout the year and very low rainfall in every month. Which statement(s) identify a biome likely to develop there?

I. A hot desert
II. A tropical forest
III. A tundra

Show answer and explanation

Answer: B. Hot deserts are characterized by high temperatures and very low rainfall, so the stated climate makes a hot desert likely.

A: adds II by treating high temperature alone as sufficient for tropical forest, despite the very low rainfall.

C: includes II, which requires high rainfall, and III, which is characterized by low temperatures.

D: accepts both tropical forest and tundra; the low rainfall excludes the former, and the high temperatures exclude the latter.

Remember: use both temperature and rainfall to distinguish biomes.
