GEO 111-W03 QUIZ 3

Is column B, warm air or cold air, and why.

Answer explanation

Column B: Cold air

"It is causing the molecules to cluster together putting more molecules in a smaller package."

C+D on the convection graph are called

Answer explanation

pressure thats on the earth's surface

Is column A warm air or cold air, and why?

• It Causing more molecules to exist above a higher elevation, cause at higher ele. column A has more molecules therefore has higher pressure."

• Cold air

• warm air

• It causes more molecules to exist at a lower elevation

A+B on the basic convection graph are called

Answer explanation

The Pressure aloft (High and low)

PGF impacts pressure by

Answer explanation

1) Forcing molecules in area of low pressure

2) Increasing surface pressure

3) forcing molecules away in areas of high pressure, reduc. surface pressure

The (******) the PGF, the (*******) the transfer of molecules will be.

(STRONGER or WEAKER?)

• stronger, weaker

• weaker,weaker

• stronger,stronger

• weaker,stronger

Answer explanation

Stronger;stronger

he (stronger/weaker) the PGF, the (stronger/weaker) the winds

• stronger, stronger

• weaker,stronger

• weaker,weaker

• stronger,weaker

The transfer of molecules associated with the Pressure Gradient Force creates what

Answer explanation

creates wind aloft and on the Earth's surface.

What is the 500 mb mark?

• helps create wind aloft

• dividing line btw aloft air and surface air

• 
  

  The force exerted by the mass and density of the earths atmosphere.

• it creates surface low pressure

Pressure Gradient Force (PGF)

• Always moves from areas of high pressure to low pressure. higher elevation to lower elevation.

• 1) Tends to be colder air

  2) Pressure changes quickly above it

  3) Created by pressure aloft

  4) flows to cold air and increases surface pressure

  5) High ( Diverenge)

• has air rising and converging air in

• higher elevation to lower elevation.
