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.
The stream gradient becomes nearly flat, and lateral deposition of sediments becomes important as the stream meanders across the valley floor. In all stages of stream erosion, by far the most erosion occurs during times of flood, when more and faster-moving water is available to carry a larger sediment load. In such processes, it is not the water alone that erodes: suspended abrasive particles, pebbles, and boulders can also act erosively as they traverse a surface, in a process known as traction.
