Traction - GCSE Geography Definition

In GCSE Geography, "traction" refers to a transportation process through which large rocks and stones are moved along the bottom of a river or the seafloor. This happens when strong water currents push these heavy materials, causing them to roll or slide, helping to shape the landscape by eroding and depositing materials. This process usually happens in areas with fast-moving water where the force is strong enough to move larger particles. Understanding traction is key to explaining how rivers and coastal environments change over time.
