  • Q4
    A crack in a rock can fill with water which then freezes as the temperature drops. As the ice expands, it pushes the crack apart, making it larger. This repeated process of freezing and thawing causes crack to become larger until the rock splits.

  • Q6
    Temperature fluctuations affect rocks. The tendency of minerals to expand and contract based on temperature. Rocks contain various minerals, and these minerals expand and contract at different rates when exposed to rapid temperature fluctuations such as day-night cycles. This causes stress and small cracks within the rocks and the gradual breakdown of the rock.
