According to An Inconvenient Truth, what is the role of infrared radiation in global warming?
( 1 point )
A.) All of the sun's energy is converted to infrared radiation and then remains in the atmosphere. This warms the atmosphere.
B.) Over time, infrared radiation makes the atmosphere thinner. This warms the atmosphere.
C.) Greenhouse gases trap some infrared radiation in the atmosphere. This warms the atmosphere.
C.) Greenhouse gases trap some infrared radiation in the atmosphere. This warms the atmosphere.
C.) Greenhouse gases trap some infrared radiation in the atmosphere. This warms the atmosphere.
The correct answer is C.) Greenhouse gases trap some infrared radiation in the atmosphere. This warms the atmosphere.
To find this answer, one can first start by understanding the concept of global warming and the role of infrared radiation. Global warming refers to the increase in average temperature of the Earth's surface caused by human activities, primarily the emission of greenhouse gases.
Next, one can refer to the documentary "An Inconvenient Truth," which highlights the issue of global warming. The film emphasizes the role of greenhouse gases in trapping heat in the atmosphere, leading to the warming of the Earth.
To further support this, it is important to understand that when the sun's energy reaches the Earth's surface, it is absorbed and re-emitted as infrared radiation (or heat). This heat is then supposed to escape back into space. However, greenhouse gases, such as carbon dioxide, methane, and water vapor, act as a blanket, trapping some of this infrared radiation in the atmosphere. As a result, the atmosphere and the Earth's surface warm up.
Therefore, based on this understanding, the correct answer is C.) Greenhouse gases trap some infrared radiation in the atmosphere, which warms the atmosphere.
