What is Geology of Connecticut?
[[Connecticut]] is a [[US state]]. It is in the north-eastern side of the country. As part of the [[New England]] [[region]], Connecticut has undergone much [[geologic]] change. It has been shaped by [[plate tectonics]], [[volcanism]], and [[glacial]] activity. == Appalachian Mountains == During the early [[Triassic]] Era, the [[super-continent]] [[Pangea]] was formed as the [[Iapetus Ocean]] closed up and the [[proto-North American]] continent [[wikt:collide|collided]] with [[Avalonia]] (modern day [[Africa]]). This caused great uplift and the creation of the [[Appalachian Mountains]]. The [[erosion]] of the Appalachian Mountains now exposes and lifts up [[metamorphic rock]]s that used to be very deep in the [[Earth]]'s. == Eastern Border Fault == About 200 [[million]] years after this collision and the formation of Pangea, during the middle of the [[Mesozoic Era]], the [[Atlantic Ocean]] floor started spreading. This caused a lot of stress. This caused a [[geologic fault]]. Connecticut's famous Eastern Border Fault was created. As a result, the land west of this fault was downset, creating a rift valley and causing the land to tilt an average of 15 to 25 degrees. The fault is currently inactive. The formation of this basin eventually refilled with soft fluvial and alluvial sediments. == Ice Age == During [[Ice Age]]s, glacial activity shaped much of New England's landscape, eroding mountains, leaving [[glacial till]] scattered everywhere, and forming glacial lakes. At its greatest extent, one of these glaciers leaves behind a [[moraine]] which became [[Long Island]]. One of the biggest [[glacial lake]]<nowiki/>s of the time was Glacial Lake Hitchcock. It formed when the Laurentide [[ice sheet]] retreated and [[glacial meltwater]] began to accumulate at the glacier’s terminal moraine in Rocky Hill, Connecticut and back up into the [[Connecticut River]]. The glacial lake left behind a soft, varved landscape, gathering [[silt]] and sand in the summertime due to the influx of glacial meltwater and clay in the
