Appalachians are range of low mountains and hills running parallel to Atlantic Coast and about one to two hundred miles in land.
Along center of Great Plains, flowing south from Canadian border to Gulf of Mexico is Mississippi River. This river together with Missouri which joins it from west and Ohio which joins it from east, forms central river system of United States. In north are five Great Lakes — Lake Superior, Lake Huron, Lake Michigan, Lake Erie and Lake Ontario which empty into Atlantic Ocean through St. Lawrence River.
