Atmospheric Pressure and Wind Patterns

The video tutorial explains global air circulation, focusing on how air moves around the Earth. It covers the Earth's shape, the role of latitudes, and the significance of pressure belts. The tutorial also discusses wind patterns, the Coriolis force, and different types of winds, such as tropical easterlies, westerlies, and polar easterlies. The video concludes with a summary of these concepts, emphasizing the importance of understanding air circulation for geography learners.

What is the shape of the Earth as understood by geography learners?

• Cubical

• Spherical with uneven shape

• Flat

• Perfectly round

Why does the equator have low pressure?

• It is far from the sun

• It receives direct sun radiation

• It is covered by ice

• It is at a high altitude

What happens to air as it rises and reaches the tropopause?

• It diverges

• It remains still

• It converges

• It descends

At which latitude does air start to descend, creating high pressure?

• 30 degrees

• 0 degrees

• 60 degrees

• 90 degrees

What is the name of the pressure belt found between 0 to 30 degrees?

• Subtropical high pressure belt

• Polar high pressure belt

• Subpolar low pressure belt

• Equatorial low pressure belt

Which cell is located between 30 to 60 degrees latitude?

• Hadley cell

• Ferrel cell

• Polar cell

• Equatorial cell

What force affects the movement of wind due to Earth's rotation?

• Gravitational force

• Magnetic force

• Coriolis force

• Electromagnetic force

In which direction does the wind move in the northern hemisphere due to the Coriolis force?

• Downwards

• Upwards

• To the right

• To the left

What are the winds called that move from the east in the subtropical high pressure area?

• Trade winds

• Polar easterlies

• Westerlies

• Tropical easterlies

Which type of winds are found between 30 to 60 degrees latitude?

• Westerlies
