Select all of the following statements that are TRUE. A. Since 1900, mean temperature on Earth has increased by at least 0.8 °C. B. Since 1900, mean temperature on Earth has increased by 2 °C. C. Scientists generally agree about the reality of global warming. D. Earth has always had warmer and colder cycles and this is what is happening now. E. Greenhouse gases are those responsible for global warming. F. The most common form of fossil fuel is coal. G. CO2 is a greenhouse gas so more CO2 means higher temperature. Which of the following are expected due to warming global temperatures? A. Longer growing seasons B. Less snow and sea ice C. Higher ocean pH

8. Which statement does BEST describe the greenhouse effect? A. The process of the atmosphere keeping the Earth's surface dense. B. The process of the atmosphere keeps us from floating into space. C. The process of the atmosphere reflecting all of the Sun's heat back into space. D. The process of the atmosphere trapping the sun's radiation, and making the Earth warm and livable for humans. 9. Which statement does BEST describe global warming? A. An increase in the earth's atmospheric temperatures due to an increase in the greenhouse effect. B. An increase in the earth's atmospheric and oceanic temperatures caused by stronger greenhouse effect due to human activities. C. An increasing temperature phenomenon that affects all countries due to increased human activity that emit greenhouse gases. D. An increasing temperature phenomenon that affects the world due to an increase of human population that destroys the atmosphere. 10. Why is human activity a contributor to increased carbon dioxide concentration in the atmosphere? 1. Burning of fossil fuels, improper waste disposal, and wasting of resources are some activities humans do that emits carbon dioxide into the atmosphere. II. Destruction of earth's natural resources, disregarding the importance of energy conservation are some activities humans do that contribute to the increase of carbon dioxide concentration in the atmosphere, III. Humans are naturally caring for the environment; humans take care of the natural resources that we use to survive. IV. Human activity greatly affects the condition of the atmosphere. If human activity destroys the atmosphere there will be problems with the environment. A. I, II, IV C. I, II B. I, II, III D. I only
