Describe the three pieces of evidence Wegener used to support his theory of continental drift.
fossils, land features, climate
Describe the steps needed for a metamorphic rock to become a sedimentary rock. (Use the correct vocabulary)
the rock would become soil through weathering and exposure, then through erosion and deposition the soil becomes sediments, which through lithification and deposition become a sedimentary rock
Give an example of each type of rock.
