Questions 6 to 10 are based on the following passage:
More than a century ago, the relationship between glacial ice and the amount of water in the ocean basins was first seen. When the great ice sheet covered vast land areas, the sea level was lowered because the normal return of water from land to the ocean was reduced. As a result, the sea level rose as Ice Age glaciers melted allowing the melted waters to flow into the ocean. If all the glacial ice on the surface of the earth today should melt, the sea level might rise by more than 150 feet. Shoreline variations are also produced through elevation or depression of the land. During times of glacier formations the great weight of the ice slowly depressed the earth's crust. Removal of the weight through glacier melting allowed the slow return of the crust to its former position. Changes in the Great Ice climates from cool and wet to warm and dry produced climate changes far from the glaciated area. For example, at times of cool-wet glacial climmates, levels of inland lakes rose, in contrast to the depression of sea level. During the warm-dry interglacial climates, lake levels were lowered. The ancient lake Bonneville, largest of the glacial lakes in Western United States, once covered more than 20,000 square miles. It had a maximum depth of more than 1,000 feet. Great Salt Lake in Utah is the shrunken remnant of this once large lake.
Although the first time that early man walked on the earth is uncertain, he is largely a product of the Great Ice Age. Present information shows that during this time he evolved rapidly both physically and culturally. His most primitive tools and skeletal remains have been found in some of the oldest deposits contemporary with the Great Ice Age in Africa, Asia and Europe. These are often associated with remains of extinct animals. With the disappearance of the great ice sheets, the Bronze and Iron Age cultures evolved. About this time many animals suited to cooler climates died.
Although much remains to be learned, the story of the Great Ice Age is being unfolded through the efforts of specialists in many fields. Recording field observation, new theories and methods, and worldwide studies of existing glaciers are bringing a clearer understanding of the Great Ice Age.
