Untreated, an episode of mania can last anywhere from a few days to several months. Most commonly, symptoms continue for a few weeks to a few months. Depression may follow shortly after, or not appear for weeks or months. Many people with bipolar I disorder experience long periods without symptoms in between episodes. A minority has rapid-cycling symptoms of mania and depression, in which they may have distinct periods of mania or depression four or more times within a year.
Gypsum rocks are sedimentary rocks made up of sulfate mineral and formed as the result of evaporating sea water in massive prehistoric basins. This rock is found in many parts â¦ of the world. Gypsum deposits lie in flat beds of about six to eight feet in thickness, and are often inter-layered with limestone or shale.
Metamorphic Rocks Lesson #14. Rocks are formed on Earth as igneous, sedimentary, or metamorphic rocks. Igneous rocks form when rocks are heated to the melting point which forms magma. Sedimentary rocks are formed from the cementing together of sediments, or from the compaction (squeezing together) of sediments, or from the recrystallization of new mineral grains which are larger than the original crystals.
