Air pressure

Rekha wakes up on a rainy morning. She realizes that it is heavily raining outside her house, whereas when she visits her aunt, she observes the weather and sees that is it sunny. What is the reason for this?

• There is low pressure at Rekha's and high pressure at her aunts

• The earth is moving so weather differs from place to place

• The weather keeps changing because of force of gravity

• All of the above

The following is a picture of

• The tools are inside a Stevenson Screen

• The tools are inside a Barometer

• The tools are inside a Hydrometer

• None of the above

Pressure is the effect of

• the weight of all the air above pressing down
• water vapor in the atmosphere
• greenhouse gases
• solar radiation

• increasingly clear skies and dry weather
• increasingly cloudy skies and possible storms

In what direction(s) does air exert pressure?

• everywhere
• no where
• there is no pressure
• downward
