The area where you feel the burning sensation is in the ball of the foot â medically referred to as the forefoot â under the top or heads of the metatarsal bones, the five long bones in the feet that connect to the toe bones.
Glaciers erode the land in two ways, by plucking and abrasion. Plucking is the process when a glacier picks up rocks. The weight of a glacier makes it easy to break rocks and boulders in pieces.
During erosion, part of the geologic cycle, land is worn away and carried elsewhere by elements like wind and rain. Rock and tiny pieces of rock called silt are carried away to make up sediment. Sediment builds up in areas through a process called deposition. Of course, all that rock and silt has to go somewhere. Sometimes deposition is as dramatic as the creation of a new island like Surtsey, but often it affects much smaller, incremental changes in land that, over time, can become new landforms like mountains and deltas.
