Select the correct rock type connected with its mode of origin. 4. A rare rock formation is found 300 km from a matching formation. The continent on which it is found is part of a plate that is moving at a rate of 36 mm/year. Which answer most closely approximates how many years ago the matching rocks were separated? 5. The theory of plate tectonics states the following: 6. Magma circulates in convection cells in the 7. The lithosphere includes 8. The Earth is about billion years old. 9. The elements of Earth are separated such that the 10. Worldwide, the largest density-dependent cause of death is 11. Population size can be estimated using the formula 12.

If a population s age structure diagram looks like a pyramid, the population 18. To determine the number of individuals that will be added to a population in a specified time we multiply the growth rate (r) by the 19. The birth rate of a population is expressed as a 1

Which of the following is NOT a type of interspecific interaction? 27. In his 1798 book, An Essay on the Principle of Population, Thomas Malthus stated the power of [the Earth s human] population [to increase] is indefinitely greater than the power in the earth to produce subsistence for man. He explained that our population increases exponentially while we can only increase our food supply linearly. Using our modern terminology, what did Malthus mean by the power of the earth to produce subsistence for man? 28. An exotic species is one which an ecosystem 29. Some predators feed preferentially on the most abundant prey. This type of predation is 30. An ecosystem s carrying capacity for a population is determined by all of the following factors EXCEPT 31. If a population of 100 birds increases to 120 birds the following year, r =. 32. What occurs when a small group from a population colonizes a new area? 33. The variety of genes within a species is called its 2

Which of the following is not true about the sun s energy heating the Earth? 54. Which of the following is the best description of albedo? 55. Which level of the atmosphere contains the ozone layer? 56. In which level of the atmosphere does weather occur? 5
