  • Influences on Weathering | Physical Geography

    Some minerals in a rock might completely dissolve in water, but the more resistant minerals remain. In this case, the rock’s surface becomes pitted and rough. When a less resistant mineral dissolves, more resistant mineral grains are released from the rock. Climate. A region’s climate strongly influences weathering.
