Fractures allow erosion to occur faster. When there are fractures in the bedrock, water or plant roots
can infiltrate the cracks. When water enters cracks in arctic zones, it freezes and expands by 9%. This
allows the cracks to get bigger and bigger- allowing more erosion to occur at a faster rate. When plant
roots enter fractures they continue to grow and begin to take over the bedrock. As the roots grow, so
does the fracture, which again, leads to larger cracks which increases the rate at which erosion occurs.
