What is water vapor and what role does it play in the atmosphere?

Water vapor is also the most important greenhouse gas in the atmosphere. The water vapor molecules, in turn, radiate heat in all directions. Some of the heat returns to the Earth’s surface. Thus, water vapor is a second source of warmth (in addition to sunlight) at the Earth’s surface.

What is the importance of moisture in the atmosphere?

Atmospheric water vapour is an important factor in weather for several reasons. It regulates air temperature by absorbing thermal radiation both from the Sun and the Earth. Moreover, the higher the vapour content of the atmosphere, the more latent energy is available for the generation of storms.

How does water vapor move in the water cycle?

Explore water vapor in the air in part two of the water cycle series. This second part of our series on the water cycle illustrates the way in which evaporation and winds combine to move water from the ocean to the land. Use Up/Down Arrow keys to increase or decrease volume.

Why is condensation important to the water cycle?

Condensation and the Water Cycle. Condensation is the process by which water vapor in the air is changed into liquid water. Condensation is crucial to the water cycle because it is responsible for the formation of clouds. These clouds may produce precipitation, which is the primary route for water to return to the Earth’s surface within

How does water vapor affect the climate system?

The comments by NOAA concerning the role of water vapor in global warming are generally judicious and exemplary. Unfortunately they are marred by the presumption that water vapor only enters into the climate system as a feedback effect. Water Vapor is the most abundant greenhouse gas in the atmosphere […]

What is the role of the ocean in the water cycle?

Water vapor condenses into droplets, forming clouds What role does the ocean play in the water cycle? Water is evaporated from the ocean Water that fills the cracks and openings in underground soil and rock layers is called ___________. Groundwater
