Why is the water cycle important to the troposphere?
The atmosphere is full of water Although the atmosphere may not be a great storehouse of water, it is the superhighway used to move water around the globe. Evaporation and transpiration change liquid water into vapor, which ascends into the atmosphere due to rising air currents.
Does the water cycle occur in the troposphere?
Because air is cooler at higher altitude in the troposphere, water vapor cools as it rises high in the atmosphere and transforms into water droplets by a process called condensation. The water droplets that form make up clouds.
What atmosphere does the water cycle occur in?
In the cool air, water vapor is more likely to condense from a gas to a liquid to form cloud droplets. Cloud droplets can grow and produce precipitation (including rain, snow, sleet, freezing rain, and hail), which is the primary mechanism for transporting water from the atmosphere back to the Earth’s surface.
Why does the troposphere contain so much water vapor?
Explanation: The troposphere does contain the most water vapor out of the atmosphere because the troposphere is where all the weather conditions like: rain cloudy, hurricanes take place and all the weather conditions have water vapor because most of the weather conditions have clouds, or water vapor.
What are 3 facts about the troposphere?
Fact Sheet
- The troposphere contains 75% of the atmosphere’s total mass.
- In either space or time the troposphere is not constant.
- Weather occurs in the troposphere.
- The troposphere is 10 miles from the equator.
- The troposphere is 5-7 miles above the poles.
- Does not contain ozone.
What are two reasons troposphere can contain so much water vapor?
Gravity, combined with the compressibility of air, causes the density of an atmosphere to fall off exponentially with height, such that Earth’s troposphere contains 80% of the mass and most of the water vapor in the atmosphere, and consequently most of the clouds and stormy weather.
How does the water cycle occur in the troposphere?
The exchange and movement of water between the earth and atmosphere is called the water cycle. The cycle, which occurs in the troposphere, begins as the sun evaporates large amounts of water from the earth’s surface and the moisture is transported to other regions by the wind.
Why is water vapor important to the troposphere?
Water vapor plays a major role in regulating air temperature because it absorbs solar energy and thermal radiation from the planet’s surface. The troposphere contains 99% of the water vapor in the atmosphere. Water vapor concentrations vary with latitudinal position(north to south).
How does evaporation and transpiration affect the water cycle?
Evaporation and transpiration change liquid water into vapor, which ascends into the atmosphere due to rising air currents. Cooler temperatures aloft allow the vapor to condense into clouds and strong winds move the clouds around the world until the water falls as precipitation to replenish the earthbound parts of the water cycle.
How does convection transport heat in the troposphere?
Convection is the mechanism responsible for the vertical transport of heat in the troposphere while horizontal heat transfer is accomplished through advection. The exchange and movement of water between the earth and atmosphere is called the water cycle.
