Answer:
Physical weathering
Explanation:
The unfreezing and refreshing causes friction which wears down the rock
Answer:
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.
