Question

Assume that water filling a crack in a rock undergoes cycles of freezing and melting. Which of the following statement is true? a.Water expands as it melts, causing the crack walls to be pushed apart. b.Water expands as it freezes, causing the crack walls to be pushed apart. c.Water shrinks as it freezes, causing the crack walls to be drawn closer together. d.Water shrinks as it melts, causing the crack walls to be pulled closer together.

Answer 1

C. Water expands as it freezes, causing the crack walls to be pushed apart

Step-by-step explanation:

Answer 2

Answer: Water expands as it freezes, causing the crack walls to be pushed apart

Explanation: Although I will like to believe that this question is a geology/Physics/chemistry/geography question.

Expansion of water occurs during freezing. And in expanding, the ice pushes the crack in the wall apart.
