8 18. Base your answer to the following question on the following map and passage. The map shows the extent of summer ice-melt zones on Greenland in 1992 and The summer melt zone is an area where summer heat turns snow and ice around the edges of the ice sheet into slush and ponds of meltwater. Three coastal locations are shown on the map. Arctic Meltdown Scientists are concerned because average arctic temperatures are rising. The Greenland Ice Sheet, the dominant area of continental ice in the arctic region, broke all previous records for melting in In 2004, the total amount of ice resting on top of the continental crust in the arctic region was estimated to be about 3,100,000 cubic kilometers. If all this ice were to melt, the ocean levels would rise approximately 8.5 meters. A reduction in ice-covered areas exposes more land surfaces.

Describe one characteristic of the star Spica that causes it to have a greater luminosity than Barnard's Star. Base your answers to questions 44 and 45 on the passage below. The Moon Is Moving Away While Earth's Rotation Slows Tides on Earth are primarily caused by the gravitational force of the Moon acting on Earth's surface. The Moon causes two tidal bulges to occur on Earth: the direct tidal bulge occurs on the side facing the Moon, and the indirect tidal bulge occurs on the opposite side of Earth. Since Earth rotates, the bulges are swept forward along Earth's surface. This advancing bulge helps pull the Moon forward in its orbit, resulting in a larger orbital radius. The Moon is actually getting farther away from Earth, at a rate of approximately 3.8 centimeters per year. The Moon's gravity is also pulling on the direct tidal bulge. This pulling on the bulge causes friction of ocean water against the ocean floor, slowing the rotation of Earth at a rate of second per 100 years. 44. Explain why the force of gravity between the Moon and Earth will decrease over time.

17 45. In 100,00 years, the rotation of Earth will be slower by how many seconds?

Meteorite Composition Meteors that strike Earth's surface are called meteorites. Analysis of meteorite composition has provided scientists with information regarding the formation of Earth and our solar system, and possibly the development and evolution of life on Earth. Two types of meteorites are iron meteorites and chondrites. Iron meteorites consist mostly of iron and nickel, and are inferred to be from core materials of early planetary bodies in our solar system. More than 60% of meteorites studied have been identified as chondrites. Chondrites are made of millimeter-sized spheres of olivine and pyroxene crystals embedded in a mass of mineral and metal grains. The chondrites are thought to represent fragments of the earliest solid materials in our solar system. One type of chondrite, the carbonaceous chondrite, contains water, organic compounds, and minerals that represent the chemical composition necessary for life to form. 79.

Base your answer to the following question on the passage below and on your knowledge of Earth science. Coral Reefs and Ocean Currents The location of shallow-water coral reefs is controlled largely by warm-water temperatures, which originate in tropical regions and are then widely spread by ocean currents. Major surface ocean currents flow in circular patterns called gyres. Ocean current gyres flow in a clockwise direction in the Northern Hemisphere, and flow in a counterclockwise direction in the Southern Hemisphere. This pattern of circulation generally moves warm water from equatorial regions into the shallow waters along eastern continental coasts. This extends the range of coral reef growth approximately 5 of latitude beyond both the tropic of Cancer and the tropic of Capricorn. Which Earth motion causes the Coriolis effect that results in the curving of the planetary winds and surface ocean currents?

The rare isotopes found in the lava are similar to those found in ancient asteroids. This fact leads scientists to infer that the lava may be as old as our solar system and that it comes from deep inside the mantle near Earth's outer core. Nyiragongo is one volcano in a ring of many volcanoes surrounding an area that is domed upward nearly a mile above sea level, causing scientists to infer that a new mantle hot spot is forming there. Two rocks, scoria and basalt, have formed from the cooled lava that erupted from Nyiragongo. Describe the texture of each rock.

Base your answer to the following question on the passage below. Earth's Early Atmosphere Early in Earth's history, the molten outer layers of Earth released gases to form an early atmosphere. Cooling and solidification of that molten surface formed the early lithosphere approximately 4.4 billion years ago. Around 3.3 billion years ago, photosynthetic organisms appeared on Earth and removed large amounts of carbon dioxide from the atmosphere, which allowed Earth to cool even faster. In addition, they introduced oxygen into Earth's atmosphere, as a by-product of photosynthesis. Much of the first oxygen that was produced reacted with natural Earth elements, such as iron, in the lithosphere and produced new varieties of rocks and minerals. Eventually, photosynthetic organisms produced enough oxygen so that it began to accumulate in Earth's atmosphere. About 450 million years ago, there was enough oxygen in the atmosphere to allow for the development of an ozone layer 30 to 50 kilometers above Earth's surface. This layer was thick enough to protect organisms developing on land from the ultraviolet radiation from the Sun. Identify one mineral with a red-brown streak that formed when oxygen in Earth's early atmosphere combined with iron.
