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.
Water causes much erosion. When it falls as acid rain, it can dissolve rocks that are sensitive to acid. Marble & limestone weather when exposed to the rain. LEACHING by ground water: water soaks into the soil, picks up chemicals. This allows the water to leach or dissolve rocks it comes in contact with at bedrock. WAVE ACTION at the beach: the waves tumble rocks. The action of waves on a beach causes much erosion. The waves pound on the rocks & over time, cliffs crumble.
