Kiera's ss project2012

  1. 1. he Coastal Plain extends from the Fall Zone eastward to the Atlantic Ocean. Throughthe Fall Zone, the larger streams cascade off the resistant igneous and metamorphic rocksof the Piedmont to sea level. Large tidal rivers, the Potomac, Rappahannock, York, andJames, flow southeastward across the Coastal Plain to the Chesapeake Bay. The Bay, inturn, empties into the Atlantic Ocean.The topography of the Coastal Plain is a terraced landscape that stair-steps down to thecoast and to the major rivers. The risers (scarps) are former shorelines and the treads areemergent bay and river bottoms. The higher, older plains in the western part of theCoastal Plain are more dissected by stream erosion than the lower, younger terrace treads.This landscape was formed over the last few million years as sea level rose and fell inresponse to the repeated melting and growth of large continental glaciers and as theCoastal Plain slowly uplifted. During the glacial maxima, much of the continental shelfwas emergent and the Susquehanna flowed through the Chesapeake lowland and acrossthe exposed shelf to the sea 80 km or more to the east. The Chesapeake Bay was createdabout 5000 to 6000 years ago when the lower course of the Susquehanna River throughthe Chesapeake lowland was flooded as meltwater from the large Pleistocene continentalglaciers raised sea level. Continuing sea level rise and shoreline erosion caused the bay toexpand its aerial extent
  2. 2. Lake Drummond The Dismal Swamp is one of Virginias most interesting natural features. It is a huge wetland area in southeastern Virginia. It provides protection and food for many types of wildlife. The wildlife include deer, rabbits, raccoons, foxes, bobcats, and even bears. Birds, snakes, frogs and turtles can also be found here. Virginias largest natural lake, Lake Drummond, isDismal Swamp located here.
