Chapter 16 sections 1-2 Flashcards
what happens to air is about you to hold water vapor is the air gets warmer
The relative humidity increases
what happens to the relative humidity is the amount of water vapor in the air stays the same but the air gets colder
The relative humidity increases
why do you want to droplets form on the outside of a glass of ice water
The arrow next to the glass become saturated then cools to below its dewpoint so the water vapor condenses on the glass
what is a cloud made of
millions of water droplets or ice crystals
what are two ways in which clouds are classifieds
by form and by altitude
this cloud cover large areas and forms and forms in layers
stratus clouds
this cloud is found at high altitude’s and forms when the wind is strong
cirrus clouds
this cloud produces thunderstorms
cumulonimbus cloud
this crowd has a flat bottom and often indicates Fairweather
cumulus clouds
this cloud produces continuous rain
nimbostratus clouds
how does sleet form
sleet forms by rain going through a layer of freezing air
how does snow form?
Snow forms when temperatures are so cold that water vapor turns directly to a solid
why can hail become very large and heavy
hail collects water drops as it falls. And updraft can sense the hell back up where the water drops freeze to form another layer of ice this process can be repeated many times, producing many layers
what kind of friend happens when a warm air mass moves over a cold denser air mass
A warm front
what kind of friend happens when the cold air mass needs a warm air mass but the two remain separated
A stationary front
