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 actions of erosion and deposition work together to alter existing landforms and create new ones. Deposition occurs when silt, sand and other materials are carried by flowing water and deposited at other places on the Earth's surface. Moving waters, such as rivers and streams, are the most important natural agents of erosion. Whenever it rains, water washes over the land, picks up loose soil, and carries it away. Water also washes weathered rocks (rocks altered through a process called weathering) into rivers and streams.
