    Development Of Landscape Features

    Base your answers to questions 1 on the passage and map below and on your knowledge of Earth science. The map shows glacial features found in Mendon Ponds Park.

    Mendon Ponds Park

    Mendon Ponds Park, in New York State, is listed in the National Registry of National Landmarks due to its outstanding glacial landscape features. Glacial ice that covered most of New York State retreated northward at the end of the last ice age. As this glacial ice melted, great amounts of sediments were deposited at the glacier’s southern edge. Four glacial features dominate the park’s landscape. Kettles are bowl-shaped depressions formed when buried blocks of glacial ice melt. If the depressions fill with water, they are called kettle lakes. The Mendon Park ponds are all kettle lakes. Eskers are ridges of sorted sediments deposited within streams flowing beneath the melting glacier. Kames are small hills of unsorted sediment deposited at the base of waterfalls formed by streams flowing over the edge of a melting glacier.

    Base your answers to questions 7 on the passage and map below and on your knowledge of Earth science. The map shows the location of the Marcellus shale formation in New York State.

    The Marcellus Shale

    The Marcellus shale is a black shale formation that was formed during the Middle Devonian Period. The shale extends from New York State as far south as Alabama. The Marcellus shale is exposed at the surface in the northern Finger Lakes region, and is buried 2.1 kilometers below the surface along the New York-Pennsylvania border.

    Geologists estimate that the Marcellus shale contains hundreds of trillions of cubic feet of natural gas. Most of the Marcellus shale does not allow fluids (gases and liquids) to flow through the rock. In order to obtain the natural gas trapped in the rock, the shale is fractured. This hydraulic fracturing consists of drilling a well, then pumping in large amounts of water containing chemicals and sand under high pressure to create cracks in the gas-bearing rock. Although this process can allow the trapped gas to be removed from the shale, opponents of hydraulic fracturing argue that the chemicals used in the process may lead to groundwater contamination.

    Base your answers to questions 15 on the passage and geologic cross section below and on your knowledge of Earth science. The geologic cross section represents rock layers of a portion of the Niagara Escarpment, and landscape features that are found in the Niagara region. The rock layers have not been overturned.

    The Niagara Escarpment

    A prominent feature found along the shore of Lake Ontario in western New York State is the Niagara Escarpment. This escarpment is the remains of an ancient seabed that was formed when the area was covered by a warm, shallow sea from approximately450 to 430 million years ago. Erosion of the Taconic Mountains to the east provided

    the sediments deposited in this basin area. From these sediments, rock layers such as shale, sandstone, and limestone formed. Later, magnesium replaced some of the calcium in the top layer of limestone, turning it into a dolostone layer. When the high ocean levels of the Ordovician Period dropped, the draining of this inland sea caused unequal erosion of the exposed layers. The South Moraine was deposited on the top of the Niagara Escarpment in this region.
