What is an upward moving current of air?
An upward moving current of air is called an updraft.
When warm air rises and cool air sinks what current is created?
Convection current
Is the pattern of warm air rising and cool air sinking is known as the conduction current?
It's known as a convection current not a conduction current :)
Is an updraft an upward moving current of cold air?
No. An updraft (updraught) is an upward moving current of warm air.
What is a current of cool air called?
A current of cool air is called a draft. Oxygen O2 and Carbon dioxide CO2
Ascending unsaturated air expands or compresses?
Expands
Why does ascending air allow for clouds form?
to form
Why does ascending air allows for clouds to form?
to form
How can a scuba diver suffer an air emoblism?
from holding their breath and ascending.
What is an autorotation?
An autorotation is the rotation of the blades of a helicopter due to the presence of ascending air.
What heat transmitting process in the atmosphere has ascending and descending air masses with different temperatures?
conduction
What color was the glowing object that Christopher Columbus reported rising from the sea and ascending into the air?
A star!
What is an air current?
The vertical rising or sinking of air is known as the air current
Why the mercury can not rise in a lab thermometer if there is air in the glass tube?
Because the pressure of air may be greater than the pressure of the ascending mercury.
Why the mercury can not rise in a lab thermometer if there is air in glass tube?
Because the pressure of air may be greater than the pressure of the ascending Mercury.
Why does ascending saturated air cool more slowly than ascending unsaturated air?
Saturated air contains relaitvely higher amount of water molecules. Thus it requires much time to cool. Whereas in case of unsaturated air, the number of water molecules are less. So, it's much obvious that lesser amount of water molecules require less time to cool.
What kind of current makes the air move?
When the air moves it is called an air current or wind
