East Tennessee's major landforms. East Tennessee is located within three major geological divisions of the Appalachian Mountains: the Blue Ridge Mountains on the border with North Carolina in the east; the Ridge-and-Valley Appalachians (usually called the "Great Appalachian Valley" or "Tennessee Valley" [a]) in the center; and the Cumberland Plateau in the west, part of which is in Middle ...
The United States Geological Survey estimates that earthquakes as large as magnitude 7.5 are possible in the ETSZ. Even though Oak Ridge, Tennessee experiences these earthquakes, the nuclear reactors in the city are rated to handle 8.0 magnitude earthquakes. So, if a 7.5 magnitude earthquake were to occur, a meltdown would be highly unlikely.
The geology of Tennessee is as diverse as its landscapes. Politically, Tennessee is broken up into three Grand Divisions : East , Middle , and West Tennessee . [ 1 ] Physically, Tennessee is also separated into three main types of landforms: river valley plain, highlands and basins, and mountains.
It is located in East Tennessee and also extends into southeastern Kentucky, northwestern Georgia, and northern Alabama. This part of Alabama is part of the Black Warrior Basin. [1] The Chattanooga Shale of East Tennessee is reported to be an extension of or correlates with the Marcellus Shale of the Appalachian region to the east. [5]
Geological formations in Tennessee largely correspond with the state's topographic features, and, in general, decrease in age from east to west. Most of the Blue Ridge Mountains in the east were formed during the Precambrian era , and contain the state's oldest rocks, igneous strata that is more than 1 billion years old.
Many communities across East Tennessee remain under water and are coping with crumbled roads, unsteady bridges and devastated utility systems. The remnants of Hurricane Helene brought rivers to ...
The Gray Fossil Site is a deposit of laminated clay and silt sediments laid down in an ancient lake that formed within a sinkhole. The deposit is oval in shape, covering an area of roughly 220 meters by 180 meters and ranging in depth from about 7 meters to 39 meters deep.
With crews set to finish remediating soil at the East Tennessee Technology Park (ETTP) this year, the U.S. Department of Energy's Oak Ridge Office of Environmental Management (OREM) is shifting ...
