The cross section below represents four different rock units. The symbol for contact metamorphism has been omitted from the cross section.
Which cross section below represents where the symbol for contact metamorphism would be located, based on the relative age sequence?

• 1
• 2
• 3
• 4

Base your answers to questions 2 and 3 on the cross section below and on your knowledge of Earth science. The cross section represents the distance and age of ocean-floor bedrock found on both sides of the Mid-Atlantic Ridge.
According to the cross section, every 1 million years, the ocean floor bedrock moves approximately

• 20 km toward the Mid-Atlantic Ridge
• 20 km away from the Mid-Atlantic Ridge
• 40 km toward the Mid-Atlantic Ridge
•  40 km away from the Mid-Atlantic Ridge

Base your answers to questions 2 and 3 on the cross section below and on your knowledge of Earth science. The cross section represents the distance and age of ocean-floor bedrock found on both sides of the Mid-Atlantic Ridge.
Which map best represents the pattern of magnetic polarity in the minerals of ocean-floor bedrock on each side of the Mid-Atlantic Ridge?

• map 1
• map 2
• map 3
• map 4

The topographic map below shows the largest island of the Hawaiian Islands.
Which map below best shows the most likely stream drainage pattern of this island?

• map 1
• map 2

Photographs A and B below show two different valleys.
Which list best identifies the agent of erosion that primarily determined the shape of each valley?

• photograph A—glacier; photograph B—river

Base your answers to questions 6 through 10 on the diagram below and on your knowledge of Earth science. The diagram represents the orbital paths of the four Jovian planets and Halley’s comet around the Sun. Halley’s comet has a revolution period of 76 years. In 1986, Halley’s comet was at perihelion, its closest point to the Sun. Letters A, B, C, and D represent locations of Halley’s comet in its orbit. Location D represents Halley’s comet at aphelion, its farthest point from the Sun. The comet’s tail is shown at perihelion and at locations B and C.
Based on the pattern shown above, which diagram best represents the correct position of the comet’s tail at location A relative to the Sun?

• diagram 1
• diagram 2
• diagram 3
• diagram 4
