Reminders • - Brown bread- (Sandstone) is a soft stone that is made when sand grains cement together. • - Cheese- (Shale) like clay that has been hardened and turned into rock. It often breaks apart in large flat sections. • - Peanut Butter & Chocolate Chips- (Conglomerate) which contains rounded rocks cemented together in a matrix. • - Mayonnaise and Raisins (Porphyry) is when jagged bits of rock are cemented together in a matrix. • - Turkey (Limestone) is a rock that contains many fossils and is made of calcium carbonate/ microscopic shells. • - Salt (Gypsum) common salt or Epsom salt is found where sea water precipitates the salt as the water evaporates.
