1. Label the Polar region, North Pole and the Equator on the graph above.2. Add the Leaf fall and Evaporation lines shown in Ross p55. Annotate graph to e!plain the variation in depth of regolith, giving e!a"ples of do"inant weathering t#pes

Diagram to show the latitudinal variation in the depth of regolith (the depth of which is determined by the rate of weathering)
