How does water vapor get into the sky?
Water vapor gets into air mainly by evaporation – some of the liquid water from the ocean, lakes, and rivers turns into water vapor and travels in the air. When air rises in the atmosphere it gets cooler and is under less pressure. The vapor becomes small water droplets or ice crystals and a cloud is formed.
Is water vapor affected by gravity?
If the pressure and temperature are such that the vapour’s pressure is higher than the vapour pressure of the liquid phase, then it will condense. The gravity effect on the vapor is the same as the gravity effect on liquid. The gravity effect will not change with the phase change of the liquid.
What are the ways that water vapor can reenter the atmosphere?
Water enters the atmosphere through evaporation, transpiration, excretion and sublimation:
- Transpiration is the loss of water from plants (via their leaves).
- Animals excrete water by respiration and by passing urine.
What happens to water vapor in the sky when it forms clouds?
Clouds form when the invisible water vapor in the air condenses into visible water droplets or ice crystals. For this to happen, the parcel of air must be saturated, i.e. unable to hold all the water it contains in vapor form, so it starts to condense into a liquid or solid form.
Where does the water Vapour go?
Water evaporates from the Earth’s surface and rises on warm updrafts into the atmosphere. It condenses into clouds, is blown by the wind, and then falls back to the Earth as rain or snow.
Is gravity greater in water?
Though it is distributed over the landscape, water has mass; the greater the mass, the greater the gravitational attraction. …
What happens to the water in the atmosphere as it rises?
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. If the temperature is cold enough, ice crystals form instead of liquid water droplets.
How does water move from the atmosphere to the ground and back?
The atmosphere is the superhighway in the sky that moves water everywhere over the Earth. Water at the Earth’s surface evaporates into water vapor which rises up into the sky to become part of a cloud which will float off with the winds, eventually releasing water back to Earth as precipitation.
What is water vapor doing when it changes to water?
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. Condensation is the opposite of evaporation.
Which part of the water cycle are caused by the force of gravity?
Gravity causes precipitation to fall from clouds and water to flow downward on the land through watersheds. Energy from the sun and the force of gravity drive the continual cycling of water among these reservoirs. As the water is heated, it changes state from a liquid to a gas. This process is called evaporation.
How does water Vapour affect the environment?
Water vapor is the most important greenhouse gas. It controls the Earth’s temperature.” It’s true that water vapor is the largest contributor to the Earth’s greenhouse effect. Because these gases are not condensable at atmospheric temperatures and pressures, the atmosphere can pack in much more of these gases .
How does water Vapour affect air pressure?
Answer: As humidity increases pressure decreases. Since water vapor is less dense than dry air if both have the same temperature, the addition of water vapor decreases the overall density of the air and lowers its pressure.
Can water vapor escape the Earth’s gravity?
Water vapor, e.g., the atmosphere, is “held against” the earth by the earth’s gravity. There may be a trace amount of the atmosphere escaping over time, but it would not be a significant amount. In order for a significant amount of water vapor to escape, it would need to achieve escape velocity…
What happens to water vapor when it rises?
Water Vapor. Water evaporates from the Earth’s surface and rises on warm updrafts into the atmosphere. It condenses into clouds, is blown by the wind, and then falls back to the Earth as rain or snow. This cycle is one important way that heat and energy are transferred from the surface of the Earth to the atmosphere,…
Why does water soak up the force of gravity?
Why does water soak upwards against gravity? Water is able to soak up against the force of gravity all thanks to a little help from capillary action. Water is wet. In scientific terms, wetting refers to the tendency of a liquid to stick to a solid.
What is the role of water vapor in the atmosphere?
It condenses into clouds, is blown by the wind, and then falls back to the Earth as rain or snow. This cycle is one important way that heat and energy are transferred from the surface of the Earth to the atmosphere, and transported from one place to another on our planet. Water vapor is also the most important greenhouse gas in the atmosphere.
