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.
Igneous rock forms from magma; no chance for fossils to form there. Metamorphic rocks are other rock types that are changed by heat and pressure; their transformation and mineral reorganization causes very few fossils to be found there.Sedimentary rock can be formed from the accumulation of sediments and are often formed near ancient shores, basins, and lake beds.If an organism dies and is covered by sediments before being rotted or eaten by predatory organisms, it could eventually become part of the sedimentary layer that becomes rock.edimentary rocks can contain fossils because, unlike most igneous and metamorphic rocks, they form at temperatures and pressures that do not destroy fossil remains. Dead orga â¦ nisms can become sediments which may, under the right conditions, become sedimentary rock.
