Among the gases in the atmosphere, only the concentration of carbon dioxide may result in preventing heat around the Earth from escaping.
举一反三
- Why is more earth's heat blocked from escaping with more carbon dioxide in the atmosphere A: Carbon dioxide prevents the sun's energy from going back into space. B: Carbon dioxide radiates the sun's energy onto the earth. C: Carbon dioxide produces more heat in the atmosphere. D: Carbon dioxide takes in the sun's energy at infra-red wavelengths.
- what the analogy is: which two things are being compared?The earth’s atmosphere is like a blanket of gases around the earth. It is only a thin layer but it helps to maintain the temperature of the earth, keeping us warm. It also offers a layer of protection from the intensity of the sun. A: earth’s atmosphere and a blanket B: earth’s atmosphere and gases C: earth’s atmosphere and a layer of protection D: earth’s atmosphere and a blanket of gases
- Carbon dioxide, which makes a ____________ between us and the sun, prevent heat from getting out of the the atmosphere easily, so the earth is becoming warmer. A: difference B: comparison C: connection D: barrier
- The concentration of carbon dioxide is caused by_______. A: the heat accumulated in the atmosphere B: the burning of coal C: the wide use of renewable energy D: the destruction of the tropical rain forest
- Some pollutants are called greenhouse gases because they . A: are beneficial for plant growth B: let sunlight enter the atmosphere but slow the loss of heat from the Earth's surface C: make up the majority of gases in the atmosphere D: none of the above
