Multiple sclerosis (MS) is an unpredictable, often disabling disease of the central nervous system that disrupts the flow of information within the brain, and between the brain and body.
The Laramide orogeny was a period of mountain building in western North America, which started in the Late Cretaceous, 70 to 80 million years ago, and ended 35 to 55 million years ago. The exact duration and ages of beginning and end of the orogeny are in dispute.welve kilometers of structural relief between basins and adjacent uplifts is not uncommon. The basins contain several thousand meters of Paleozoic and Mesozoic sedimentary rocks that predate the Laramide orogeny. As much as 5000 m of Cretaceous and Cenozoic sediments filled these orogenically defined basins.
  The Carboniferous Period occurred from about 354 to 290 million years ago during the late Paleozoic Era. The term Carboniferous comes from England, in reference to t â¦ he rich deposits of coal that occur there. These deposits of coal occur throughout northern Europe, Asia, and midwestern and eastern North America.he Carboniferous period extended from approximately 360 Mya to about 300 Mya from the end of the Devonian Period to the beginning of the Permian Period. In the middle of this â¦ period the Carboniferous Rain forest Collapse occurred and resulted in the deposition of many coal beds.
