Air Pressure and Winds

Which is TRUE

• When temperature increases, air pressure increases too

• When temperature increases, air pressure decreases

• When air is warm, it is less dense and pressure exerted becomes more

• When air is cool, it is more dense and therefore air pressure drops

Why is there wind?

• Because there is difference in pressure

• Because air moves

• Because there is difference in temperature

• All of the above

Wind is air that moves. How does air move?

• Wherever it likes

• From an area of higher pressure to an area of lower pressure

• From an area of higher temperature to an area of lower temperature

• From north to south

What does it mean by "land breeze"? Which is FALSE?

• Breeze is blowing from land to sea

• The land is cooler than the sea

• Breeze is blowing towards land from sea

• The sea has lower pressure

What is the Coriolis Effect?

(you may select more than one option if applicable)

• It is due to the rotation of the earth about it's axis

• It causes that blows over significant distances to deflect

• Wind that blows in the Northern Hemisphere deflects to the left

• Wind that blows in the Southern Hemisphere deflects to the left

Which is TRUE?

• Southern Hemisphere experiences summer from June to September

• Northern Hemisphere experiences winter from October to February

• When the Northern Hemisphere is experiencing summer, the Southern Hemisphere is usually experiencing winter

• Temperature is warmer in the Northern Hemisphere than the Southern Hemisphere from June to September

A monsoon wind is a seasonal wind that blows across regions and changes in direction due to seasonal changes (summer and winter.)

What do you think it means when there is a "Northeast Monsoon winds"?

(you may select more than one option if applicable)

• Winds are blowing from the Northeast

• Northern Hemisphere is experiencing winter

• Southern Hemisphere has higher pressure

• Southern Hemisphere is experiencing summer

From June to September, the ________________ Hemisphere experiences winter and the _______________ Hemisphere experiences summer. This causes winds to blow from higher pressure area in _________________ towards lower pressure area in __________________.

(Which option has the most appropriate answers for each blank?)

• Northern, Southern, Central Asia and India, Australia

• Northern, Southern, Australia, Central Asia and India

• Southern, Northern, Central Asia and India, Australia

• Southern, Northern, Australia, Central Asia and India

If a monsoon wind blowing from the Southern Hemisphere towards the North changes in direction due to the Coriolis Effect, it will become the _______________ monsoon.

• Northeast

• Southwest

• Northwest

• Southeast

When monsoon winds from the Southern Hemisphere cross the Equator and enter the Northern Hemisphere...

(you may select more than one option if applicable)

• Wind deflects to the right

• Blows across the Indian Ocean

• Reaches India as the Southwest Monsoon

• Reaches India as the Northeast Monsoon
