A couple of years ago, my endocrinologist urged me to use Glucerna shakes as part of a 600 calorie a day diet he wanted me to go on. I took one look at the ingredients â 26g carbohydrate â and told him it looks more like the stimulus for a Glucose Tolerance Test than something diabetics should drink.
Sediments are the key!     The Rock cycle is a process whereby all types of rock are formed then eroded and recycled through different depositional processes. Sedim â¦ entary rocks can provide evidence that the rock cycle exists by looking at it under a microscope.
What is the Rock Cycle? Like most Earth materials, rocks are created and destroyed in cycles. The rock cycle is a model that describes the formation, breakdown, and reformation of a rock as a result of sedimentary, igneous, and metamorphic processes. All rocks are made up of minerals. A mineral is defined as a naturally occurring, crystalline solid of definite chemical composition and a characteristic crystal structure. A rock is any naturally formed, nonliving, firm, and coherent aggregate mass of solid matter that constitutes part of a planet.
