Complete the statement given below.
When wind speed is _,air pressure _. air moves from a region where air pressure is _ to a region where air pressure is _
Answers
Answer:
1) When wind speed is GREATER, air pressure is LOW.
2) Air moves from a region where air pressure is HIGH to a region where the air pressure is LOW.
Explanation:
1) By converging air molecules over a given region, we are adding molecules to our column and so the pressure should increase. ... This decreases the surface pressure which increases the pressure gradient force, which increases the wind speed and causes the air to rush in faster towards the low pressure center.
2) The wind blows because of differences in air pressure from one location to another. Wind blows from areas of high pressure toward areas of low pressure. If the high pressure area is very close to the low pressure area, or if the pressure difference is very great, the wind can blow very fast.
