MMS Global Winds and Coriolis Effect

Why are there global winds?

• because the cold air sinkes from the poles to the equator
• because the earth is rotating from east to west
• because the sun heats the air at the equator more than anywhere else on earth

Which way to the global winds blow in each hemisphere?

• east to west in Northern Hemisphere and west to east in the Southern Hemisphere
• west to east in Northern Hemisphere and east to west in Southern Hemisphere
• North to south in the Northern Hemisphere and south to north in Southern Hemisphere
• south to north in the Northern Hemisphere and north to south in the Southern Hemisphere

What is the Coriolis Effect and how does it effect global winds?

• Curving of winds due to rotation of earth curves wind counterclockwise in Northern Hemisphere and clockwise in the Southern Hemisphere
• Movement of ocean currents caused by earth rotation' counterclockwise in Northern Hemisphere and clockwise in Southern Hemisphere
• curve of global winds caused by global rotation clockwise in Northern Hemisphere and counterclockwise in Southern Hemisphere

The two most important things to hurricanes are

• high pressure and cool water
• low pressure and cool water
• low pressure and warm water
• high pressure and warm water

Why do hurricanes lose so much of their power when they hit land?

• they run into high pressure which kills hurricanes
• land is cooler than water therefore the hurricane loses the energy it needs from warm temperatures
• the land breezes shear the hurricane therefore making it harder for it to stay together
• the hurricane no longer receives heat and moisture from the warm ocean it uses for fuel

^{Which diagram shows the formation of a sea breeze?}

• diagram Y
• diagram X
• neither
• both

_{Which diagram shows the formation of a land breeze?}

• diagram Y
• diagram X
• neither 
• both

What type of winds blow constantly, predictably, and over long distances?

• land breezes
• mountain breezes
• global winds
• land breezes

Which statement correctly defines wind?

• Wind is the movement of air from areas of low pressure to areas of high pressure
• Wind is the movement of air to a colder area in the atmosphere.
• Wind is the movement of air from areas of high pressure to areas of low pressure.
• Wind is the movement of air pushed around and bouncing off Earth's surface.

How do differences in air pressure affect the movement of air?

• Air always moves from areas of high pressure to areas of low pressure.
• Air always moves from areas of low altitudes to high altitudes.
• Air always moves from areas of low pressure to areas of high pressure.
• Air always moves from east to west.
