Q

What is the Coriolis effect

A

Earth rotates west to east(counterclockwise) this causes winds to turn right in the northern hemisphere(west) and left in the Southern Hemisphere(west)

Q

What are air pressure differences caused by

A

Changes in air temperature

21
Q

What are clouds made of

A

Liquid or solid water condensing(cooling) on particles in the atmosphere

22
Q

What are the 5 main types of precipitation and describe them

A

Rain- liquid water
Snow- water vapor turns directly into liquid state
Freezing rain- freeze instantly when hit object
Hail- ice crystals form & begin to fall towards earth
Sleet- a mixture of rain and snow that freeze in way down

23
Q

Cirrus cloud

A

Composed of ice and it’s a thin wispy cloud

Fair weather

24
Q

Stratus cloud

A

Uniform grey cloud often cover entire sky

light mist or drizzle 12-24 hours before weather change

25
Q

Cumulus clouds

A

White puffy clouds look like piece of cotton

Fair/pleasant weather

26
Q

Why does water not come out of the glass and the bottle

A

The air pressure is under pushing up

27
Q

Why does the index card bend in the middle when you blow in it

A

Air pressure won’t allow card to flip

28
Q

Why won’t the card flip when you blow on it

A

Fast air creates low air pressure

29
