The Adirondack Mountains, the Hudson Highlands, the Taconic Mountains, the Green Mountains, and places like the Central Park, parts of Manhattan Islands, Vermont Landscapes are all filled with metamorphosed surface bedrocks.
Explanation:
The New York State’s geology is very ancient and belongs to the Precambrian era. These bedrocks were metamorphosed sediments formed during the Taconian Orogeny.
The mountainous highlands are composed of sedimentary metamorphic rocks. They are made up of metamorphic rocks like slate, gneiss, schist, quartz, marble, shale, and sandstone.
The mountains in New York State are very old metamorphosed from pre-existing rocks due to exposure of extreme heat and pressure and due to frictional sliding of old rocks.
