Base your answer to this question on the passage and photograph below and on your knowledge of Earth science. The photograph shows anorthositic gneiss bedrock from Whiteface Mountain in New York State.
Whiteface Mountain
Whiteface Mountain, located in the Mount Marcy region, is one of New York State's highest mountain peaks. Most of the surface bedrock on Whiteface is anorthositic gneiss made up of large, light-colored plagioclase fieldspar crystals and dark mineral bands composed of amphibole, pyroxene and garnet. The foliated crystal alignment in the gneiss was produced during a major tectonic event called the Grenville orogeny. Landslides have exposed steep slopes of this white and gray bedrock on the sides of Whiteface Mountain.
Question
The altitude of Polaris as seen by an observer on Whiteface Mountain in the Mount Marcy region will be approximately
40°
44°
74°
90°

15°
45°
75°
90°

Base your answer to this question on the model and on your knowledge of Earth science.
The model represents a cross-sectional view from Earth's surface to its center. Four layers of Earth's interior are labeled A, B, C, and D. The depth below Earth's surface of the boundary between C and D, measured from Earth's surface, is indicated.
Question
Determine the inferred pressure, in million atmospheres, and temperature, in °C, within Earth's interior at the boundary between layers B and C.
