      The unit begins with investigations into the different types of physical weathering that cause erosion (chemical processes are not covered this unit or the standards the unit addresses). It then investigates the process and effects of deposition and concludes with reasoning about the processes by which sample landforms were made.

      Weathering may be caused by the action of water, air, chemicals, plants, or animals. Chemical weathering involves chemical changes in the minerals of the rock, or on the surface of the rock, that make the rock change its shape or color. Carbon dioxide, oxygen, water, and acids may all cause chemical weathering.

      Mechanical, or physical, weathering is the breakdown into smaller pieces, while chemical weathering breaks a rock or mineral down by altering a rock or mineral’s chemical composition. Weathering can be affected by several forces, including exposure, particle size, mineral composition, and climate.
