Question

Water vapor can make up as much as 90% of the greenhouse gases by volume in Earth's atmosphere. However, water vapor is rarely identified as a major agent of climate change. What best describes the role water vapor plays in the greenhouse effect?

Answer 1

B. Water vapor has a shorter resident time in the atmosphere as it moves through the hydrologic cycle quickly.

Step-by-step explanation:

Water vapor move in and out of the atmosphere in a matter of days.

Answer 2

As it can hold CO2 and CFC, it's the major one for the greenhouse effect.

Step-by-step explanation:

Water, which evaporated from the sea and other sources, directly goes upward and stays in the form of the cloud. This cloud can change the environmental situation of any place. Such as, it can make rainfall, snowfall, etc. Along with this, it holds CO2 and CFC gas. If the cloud of any place is denser, it contains more CO2 and CFC gas, which can increase temperature and cause the greenhouse effect. For this reason, this is called the major one for the greenhouse effect.
