Pressure Belts and Wind Patterns Quiz

What is the region along the equator with low pressure known as?

• Sub Polar Lows

• Equatorial Low Pressure belt

• Polar Highs

• Subtropical High-pressure belt

Answer explanation

The region along the equator with low pressure is known as the Equatorial Low Pressure belt.

At around 30 degrees north and south, we have sinking air which forms what type of pressure systems?

• Sub Polar Lows

• Equatorial Low Pressure belt

• Polar Highs

• Subtropical High-pressure belt

Answer explanation

At around 30 degrees north and south, sinking air forms Subtropical High-pressure belts, leading to high pressure systems in those regions.

What causes the winds to bend to the right in the Northern hemisphere and to the left in the Southern hemisphere?

• Gravitational pull

• Tidal forces

• Coriolis effect

• Magnetic field

Answer explanation

The Coriolis effect causes the winds to bend to the right in the Northern hemisphere and to the left in the Southern hemisphere.

What is the region at 60-degree latitudes with a low-pressure system due to rising air known as?

• Subpolar Lows

• Polar Highs

• Subtropical High-pressure belt

• Equatorial Low Pressure belt

Answer explanation

The region at 60-degree latitudes with a low-pressure system due to rising air is known as Sub Polar Lows.

What is the name given to the regions at the poles with cold sinking air?

• Equatorial Low Pressure belt

• Subtropical High-pressure belt

• Sub Polar Lows

• Polar Highs

Answer explanation

The name given to the regions at the poles with cold sinking air is Polar Highs.

What causes the air to rise at subpolar lows?

• Coriolis effect

• Convergence

• Convection

• Tidal forces

Answer explanation

The correct answer is convergence because it causes the air to rise at sub polar lows by bringing air together from different directions, leading to upward motion.

What is the name of the regions outside the tropical region adjoining the tropical region with sinking air?

• Subtropical High-pressure belt

• Polar Highs

• Equatorial Low Pressure belt

• Sub Polar Lows

Answer explanation

The correct choice is the Subtropical High-pressure belt, which is the name of the regions outside the tropical region adjoining the tropical region with sinking air.

What is the name of the air movement from high pressure regions to low pressure regions along the equator?

• Trade winds

• Jet streams

• Cyclones

• Monsoons

Answer explanation

The name of the air movement from high pressure regions to low pressure regions along the equator is Trade winds.

What causes the winds to bend towards right and left in the Northern and Southern hemispheres respectively?

• Magnetic field

• Coriolis effect

• Tidal forces

• Gravitational pull

Answer explanation

The winds bend due to the Coriolis effect, which is caused by the rotation of the Earth. In the Northern Hemisphere, winds bend to the right, and in the Southern Hemisphere, they bend to the left.

What is the name given to the regions with rising air due to convergence at 30 and 60 degrees North and South?

• Subtropical High-pressure belt

• Polar Highs

• Sub Polar Lows

• Equatorial Low Pressure belt

Answer explanation

The correct choice is Sub Polar Lows because these regions experience rising air due to convergence at 60 and 30 degrees North and South.
