Base your answers to questions 41 through 44 on the passage and cross section below and on your knowledge of Earth science. The cross section represents the area of Scoby Hill where fi ll was added to construct a roadway.

Scoby Hill Landslides

Scoby Hill is approximately 40 miles south of Buffalo, New York. The silt layer of Scoby Hill may have been unstable ever since it formed from glacial outwash approximately 12,000 years ago. Construction of a road required the addition of fi ll, which consisted of clay, silt, sand, and pebbles. The resulting landslides that occurred were a surprise because the gradient of Scoby Hill was thought to be too low for landslides. Geologists discovered that landslides easily started because of the weight of the fi ll. In order to decrease pressure on the silt layer, engineers decided to remove the fi ll and some of the silt layer to create a level surface for the road. In addition, drain pipes were installed to lower the water table and reduce the chance of future landslides.

Base your answers to questions 51 through 54 on the passage below and on your knowledge of Earth science.

Salt — A Valuable Commodity

In New York State, salt is a valuable natural resource. Approximately 8500 square miles of New York State has bedrock that contains rock salt. The layers of rock salt formed after parts of New York State were covered by a shallow inland sea, which eventually evaporated. Groundwater dissolved some of the deeper rock salt layers and carried salty water up to the surface in central New York. Commercial salt production began in the Syracuse area in the late 1700s. Early production of salt involved heating the salty water by burning wood from the surrounding area. The heat vaporized the water, leaving salt behind. When lumber supplies dwindled, solar methods were used to evaporate the water. Although the salt industry had an overall positive effect on Syracuse, the industry in Syracuse closed down in the 1920s, leaving negative environmental effects. There are currently salt mines operating south of Syracuse and in the Finger Lakes region of New York State

The Great Unconformity

One of the world’s most famous unconformities is located in North America. This dramatic gap in the geologic record (The Great Unconformity) stretches from Arizona in the United States to Alberta in Canada. Perhaps the best place to see this unconformity is in Grand Canyon National Park, where, over the last 5 to 6 million years, the Colorado River has cut down through the overlying sedimentary rock layers to reveal the 2-billionyear-old Vishnu schist. In the Grand Canyon, the Great Unconformity exists at the bottom of the Tapeats sandstone.
