Question: 41 given a cubic piece of rock 1 m on...

Question details

4.1 Given a cubic piece of rock, 1 m on a side. Calculate the surface area of the cube. If the cube is broken down into smaller gains, each 1 cm on a side, what will be the combined surface area of the materials (i.e, of all the small cubes)? Use the calculation to explain how physical weathering promotes chemical weathering. 4.2 Explain why spheroidal (spherical) weathering is common in granite. 4.3 What are typical weathering products of granites? Note: consider the mineral assemblage and the chemical composition of granites.
