Compared to a well-sorted sample of larger-sized particles, a well-sorted sample of smaller-sized particles has greater*
The aerial photograph below shows small, circular bodies of water surrounded by sediment in an area that was once covered by glaciers.
These bodies of water are known as*
Base your answers to questions 3 on the passage and map below and on your knowledge of Earth science. The map shows a portion of Southeast Asia.
Southeast Asia Monsoons
The Southeast Asia monsoons are seasonal shifts in the direction of regional planetary winds. These shifts are related to the movement of air pressure belts as the Sun’s vertical ray changes latitude. In the late spring, winds begin to blow from the southwest, bringing moisture from the Gulf of Thailand across Southeast Asia. Rainfall reaches a peak in July and August. This moisture is partially blocked by the Annamite Mountains, located along the border between Vietnam and Laos. Therefore, the rainfall in central Vietnam is somewhat less during these months. In September, the winds reverse direction and begin to flow from the northeast across the Gulf of Tonkin and South China Sea. This wind shift begins the season of heavy rainfall in central Vietnam that continues for months.
Heavy rains occur in Cambodia and Thailand when the moist air brought by the monsoon*
Base your answers to questions 4 on the cross sections below and on your knowledge of Earth science. The cross sections represent three widely spaced rock outcrops labeled A, B, and C. Line XY represents a fault. Overturning has not occurred.
Which processes formed the unconformities shown in outcrops B and C?*
Base your answers to questions 5 on the diagram below and on your knowledge of Earth science. The diagram represents an erosional-depositional system in an arid environment, and indicates the processes occurring at various locations within the atmosphere and on the land surface. The box labeled X identifies one sand dune. Arrows represent the movement of particles.
Which agent of erosion moves the particles within this erosional-depositional system?*
Base your answers to questions 6 on the diagram below. The diagram represents the inferred stages in the formation of our solar system. Stage 1 shows a contracting gas cloud. The remaining stages show the gas cloud flattening into a spinning disk as planets formed around our Sun.
Which process was occurring during some of these stages that resulted in the formation of heavier elements from lighter elements?*
Base your answers to questions 7 on the diagram below, which shows the edge of a continental glacier that is receding. R indicates elongated hills. The ridge of sediments from X to Y represents a landscape feature.
Which feature will most likely form when the partially buried ice block melts?*
The direction of movement of the major surface ocean currents is most affected by Earth’s*
Base your answers to questions 9 on the weather map below and on your knowledge of Earth science. The map shows the location of a low-pressure system over New York State during late summer. Isobar values are recorded in millibars. Shading indicates regions receiving precipitation. The air masses are labeled. Eight locations in New York State are indicated.
Identify the location labeled on the map that will next experience a short burst of heavy precipitation, a change in wind direction, and a rapid decrease in temperature. [1]*
Base your answers to questions 10 on the map below and on your knowledge of Earth science. The map shows a river and a depositional feature at an ocean shoreline. Point A indicates a location on Earth’s surface.
Identify the name of the depositional feature surrounding location A that is forming where the river enters the ocean. [1]*
Base your responses to questions 11 on the passage below.
Frozen Mammoth
A wooly mammoth was found in 1999 buried in the frozen soil of the Siberian tundra. Carbon-14 dating indicated that it had died about 20,000 years ago. Many fossils represent only the partial remains of organisms. However, a complete mammoth with bones, skin, hair, and internal organs intact represented a unique opportunity for scientists to investigate the lifestyle of this animal and the environment in which it lived.
The low permeability of the tundra soil helped to preserve the mammoth. Explain why the tundra soil has a low permeability. [1]*
Base your answers to questions 12 on the passage and map of a portion of the East African Rift system shown below. Point X represents a location on Earth’s surface within a rift valley on the Ethiopian Dome.
The Great Rift Valley
Rifting of Earth’s crust in eastern Africa began during the Neogene Period as the Ethiopian and Kenyan Domes formed. These two huge domes were created as Earth’s mantle pushed up the overlying crust. As the crust was forced upward, the resulting tension cracked the crust, resulting in the eruption of volcanoes and the formation of large rifts. The crust continued to pull apart, forming rift valleys. These valleys have become deeper and are currently becoming filled with sediments, igneous rock, and water.
On the cross section in the image provided, draw two curved arrows, one on each side of the dashed line, to show the direction of movement of the convection currents within the asthenosphere that caused the formation of the dome and the rift valley near location X. [1]

Base your answers to questions 13 on the map in image provided, which shows elevations in feet at various points. The southern part of the map has contour lines representing elevations at 20-foot intervals. Lines AB and CD are reference lines on the map.
Explain how the contour lines indicate the direction of flow of Otter Creek. [1]*
Base your answers to questions 14 on the diagram below, which shows some processes in the water cycle.
State the relationship between the amount of precipitation in this area and the height of the water table above the impermeable bedrock. [1]*
Base your answers to questions 15 on the diagram below, which shows several different landscape features. Points X and Y indicate locations on the streambank.
Identify which point, X or Y, has more stream erosion and explain why the amounts of erosion are different. [1]
