Erosion by ground water produces karst topography, characterized by sinkholes, solution valleys, and disappearing streams. Water flows from high to low due to pressure difference 3. Constant motion though slow 4. Glaciers are systems of flowing ice that form where more snow accumulates each year than melts. As ice flows, it erodes the surface by abrasion and plucking.
Sediment is transported by the glacier and deposited where the ice melts.
A Glacier is a system of flowing ice that originates on land. Astronomical variation in solar radiation earth's orbital parameters 2. Atm changes 3. Ocean Currents 4. Wind-generated waves provide most of the energy for shoreline processes.
