Multiple choice

Consider the following statements:

  1. Weathering encompasses a group of processes by which surface and subsurface rocks disintegrates
  2. Extreme dryness reduce most weathering to a minimum
  3. Physical weathering dominates in drier and cooler climates
  4. In equatorial rain-forest climate, most rocks weather slowly Which of these are correct?

  1. 1, 2. and 3

  2. 1 and 4

  3. 2, 3 and 4

  4. 1, 2, 3, and 4
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Weathering is the in situ breakdown of rocks, which is greatly slowed by extreme dryness due to the lack of water for chemical reactions. In contrast, the high heat and moisture of equatorial rainforests cause rocks to weather very rapidly, making the fourth statement incorrect.
