How is earth's surface most likely to change as water freezes and expands on a mountain side over time? a.) erosion will cause the ice to crack the rock. b.) physical weathering will cause the ice to crack the rock. c.) deposition will cause the water to break the rock into sediment. d.) chemical weathering will cause the water to dissolve the rock.

B. Physical weathering will cause the ice to crack the rock.

The correct answer is B.

Explanation:

The Earth's surface as water freezes and expands on a mountain slope will cause ice to break the rock. This occurs because the ice occupies a larger volume than the liquid, so it displaces the rock and causes it to break. When the water that accumulates in the rocks freezes, its volume increases in solid-state and exerts a greater pressure, enough to break the rock.
