Base your answers to questions 40 and 41 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.

Base your answers to questions 51 through 53 on the passage below and on your knowledge of Earth science.

Waimea Canyon
Waimea Canyon is located on the west side of the island of Kauai, Hawaii. Waimea Canyon has been referred to as the “Grand Canyon of the Pacific.” But unlike the Grand Canyon, which was carved through horizontal layers of sedimentary rocks, Waimea Canyon was cut through basalt. The formation of this igneous rock began about 4 million years ago. Numerous lava flows followed as magma rose from deep within Earth. The canyon then was formed over time by erosional agents, causing deep, V-shaped valleys that exposed the basalt layers along the canyon walls.
Over time, the composition of the basalt, where it was exposed at the surface, was changed due to oxidation (rusting) of iron-bearing minerals, such as pyroxene and olivine. The result is a canyon with red rocks and soils.

Carrara Marble
Carrara marble is named for the town of Carrara on the west coast of Italy. This dazzling white marble has been mined since the time of the ancient Romans and remains the major industry of the area today. The marble has many commercial uses, such as tombstones, countertops, tiles, and building stones. Its chemical purity, uniform color, and hardness make this marble an ideal material for artists who carve statues from rock. Major museums around the world have statues carved from Carrara marble.
The formation of Carrara marble began 200 million years ago when a great thickness of tiny shells was deposited at the bottom of a warm, shallow sea. Over time, burial and compaction of these sediments formed sedimentary rock primarily composed of pure calcite. Approximately 27 million years ago, tectonic forces caused this area of the seafloor bedrock to be deformed and metamorphosed, forming the Carrara marble. Uplift and erosion later exposed huge formations of this famous marble.
