Carbon dioxide and methane as greenhouse gases
Question
Explain the role of greenhouse gases in maintaining Earth's temperature.
Answer
Greenhouse gases, such as carbon dioxide and methane, absorb and re-radiate infrared radiation emitted from the Earth's surface. This process helps to maintain a stable temperature on Earth by trapping heat in the atmosphere, which is essential for sustaining life.
Explanation
This question assesses the student's ability to explain the function of greenhouse gases in temperature regulation. It requires an understanding of the heat retention process and its importance for life on Earth, demonstrating comprehension of the greenhouse effect.
Common mistake
Misunderstanding the Greenhouse Effect
Students often confuse the roles of short-wavelength radiation from the Sun and infrared radiation emitted by the Earth in the greenhouse effect.
Clarify that short-wavelength radiation from the Sun passes through the atmosphere and is absorbed by the Earth's surface, which then emits infrared radiation that greenhouse gases trap, warming the atmosphere.
