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.
During the rock cycle process, sedimentary rocks can become metamorphic or igneous rocks as they are buried in the planet's crust with younger layers of rock above them. Eventually they can metamorphose under heat and pressure at great depth, or melt to form new magma. Uplifting of rock layers by earth forces can bring rocks near the surface again at any point in the cycle. Igneous and metamorphic rocks can weather to form sediments that later become sedimentary rocks. Igneous rocks can metamorphose when subjected again to heat and pressure. Metamorphic rocks can metamorphose in repeat episodes or melt into magma, which later cools to form igneous rocks.
