ASTR 1010 15.) Convection refers to a method of
a) b) c) d) e) Emitting light Producing earthquakes Forming volcanoes Transferring heat Generating aurora 16.) Which region has the lowest density?
a) b) c) d) e) Crust Mantle Core Lithosphere All 17.) Which region has the highest density?
a) b) c) d) e) Crust Mantle Core Lithosphere All 18.) Which region of Earth is likely to have the youngest geological age?
a) b) c) d) e) Bulloch county The Appalachian mountains in the northeastern United States. The deep ocean basin off the coast of North America. Volcanic terrain adjacent to the active Mauna Loa volcano in Hawaii. The geological ages of all these regions are quite similar. 19.) Which process is responsible for making the surface of the Earth geologically young?
a) b) c) d) e) Volcanism Erosion Tectonics Impact Cratering All of these 20.) Which geological process is responsible for destroying islands in the Hawaiian chain?
a) b) c) d) e) Volcanism Erosion Tectonics Impact Cratering All of these 21.) When a continental plate is pulled apart, a ______ forms.
a) b) c) d) e) Subduction zone Mid-ocean ridge. Rift valley. Plume. Volcanic plain. 22.) Volcanoes in the western continental United States are mostly related to the presence of a .
a) b) c) d) e) Subduction zone Mid-ocean ridge. Rift valley. Plume. Volcanic plain. 1.) As discussed in class, the two most important factors affecting the global atmospheric circulation of a planet are
a) b) c) d) e) Atmospheric heating, planetary rotation. Atmospheric heating, existence of oceans. Size of ice caps, existence of oceans. Size of continents, albedo of surface. Amount of volcanic activity, albedo of surface. 2.) How many large circulation cells (Hadley cells) are there in the Earth's Northern Hemisphere?
a) b) c) d) e) One Two Three Ten Varies with the season. 3.) Which region absorbs mostly visible light?
a) b) c) d) e) Ground. Troposphere. Stratosphere. Ionosphere. Exosphere. 4.) Within which region does the greenhouse effect operate?
a) b) c) d) e) Ground. Troposphere. Stratosphere. Ionosphere. Exosphere. 5.) Within which region is the ozone hole on Earth found?
a) b) c) d) e) Ground. Troposphere. Stratosphere. Ionosphere. Exosphere. 6.) If there had been no oceans on Earth, the Earth's present atmosphere would be largely composed of
a) b) c) d) e) Carbon dioxide. Oxygen. Nitrogen. Water. Carbon monoxide. 7.) The reason why the chemical reaction in the Earth's stratosphere between chlorine and ozone is so destructive is that
a) b) c) d) e) Once destroyed, ozone cannot reform. The reaction is catalytic, with the chlorine not being consumed in the process. The rate of reaction increases quickly with increasing temperature. Solar x-rays provide an abundant energy source for the reaction. All of the above. 8.) A difference between the Earth and the Moon is
a) b) c) d) e) The Earth has an atmosphere. The Moon's surface is much older. The Moon has much less iron. The Earth has a magnetic field. All of these. ...
