What happened to the water vapor in the atmosphere when the early Earth cooled?
As the earth cooled, water vapour in the atmosphere condensed to a liquid (water) and fell to the earth as rain the make the oceans.
Why is water vapor important to the atmosphere?
Water vapour forms clouds that bring rain.
What gas in the atmosphere condenses to form clouds and rain?
water vapour
Which gas traps heat into the atmosphere?
Water vapour and carbon dioxide are the main greenhouse gasses in the atmosphere
When water vapor in the atmosphere cool's it may form?
Rain is formed when water vapour cools.
When does water from the lakes and oceans enter the atmosphere?
when the water turns into gas form as water vapour
What happened to the water vapour that was in the early atmosphere?
What happened to all the water vapour in the early atmosphere
Does sunlight and heat help water enter the atmosphere to form clouds?
As the sun evaporates the water and the water turns into water vapour and rises up. When it reaches a certain height in the atmosphere, the water vapour condenses to form tiny droplets of water and thus forms clouds
Can water vapour be turned back to liquid?
Yes, in the atmosphere water vapour falls as rain.
When it reaches the atmosphere what happens to rainwater?
it becomes water vapour in the atmosphere.
Water vapour in the atmosphere is confined only to?
ionosphere
What does humidity?
Humidity is the amount of water vapour in the atmosphere
What is the process by which water in plants is tranferred as water vapour to the atmosphere?
transpiration
Is water vapour not one of the constituents in air?
Water vapour is a constituents in air because water vapour rises in the atmosphere & is always present in the atmospere in some or the other quantity.Also 0.0001% of air consist water vapour
What is the most variable in the atmosphere?
The most variable abundance in the atmosphere is Water Vapour and Ozone
What happened to the water vapor in the atmosphere when the early Earth cooled?
As the earth cooled, water vapour in the atmosphere condensed to a liquid (water) and fell to the earth as rain the make the oceans.
What is the definition Humidity?
amount of water vapour in the atmosphere, or in a gas
