Factors that affect the rate of weathering

Most weathering occurs on exposed surfaces of rocks and minerals The more surface area a rock has, the more quickly it will weather When a block is cut into smaller pieces, it has more surface area So, therefore, the smaller pieces of a rock will weather faster than a large block of rock 3 ROCK COMPOSITION- Some minerals resist weathering...
