Question

deserts are known for their extreme _________.
choose one option
a rainfall
b tree height
c dryness
d latitudes

Explanation:

Deserts are arid regions. Aridity means dryness. Rainfall is low in deserts but "dryness" directly describes the core characteristic. Tree height is not a defining feature. Latitudes can vary (e.g., hot deserts near 30°N/S, cold deserts at higher latitudes). So dryness is the most appropriate.

Answer:

C. dryness
