clouds

Question 1

what are the 3 types of cloud

Answer 1

-stratus
-cumulus
-cirrus

Question 2

how do you describe stratus clouds

Answer 2

layered clouds with little vertical uplift and spread over a wide area

Question 3

how do you describe cumulus clouds

Answer 3

have more vertical uplift, over a localised area, heaped clouds with a flat base and globular upper surface

Question 4

how do you describe cirrus clouds

Answer 4

condensed water vapour at high levels causing whisky clouds of ice

Question 5

what are the 3 levels of altitude called

Answer 5

high- cirro
mid- alto
low- stratus, cumulus, stratocumulus

Question 5

how to describe precipitation causing clouds

Answer 5

have large vertical extent, they prevent sunlight causing a grey/ black appearance

Question 6

how do you describe cumulonimbus clouds

Answer 6

thick dark grey clouds, have large vertical extent, cloud spreads at top causing an anvils head

Question 6

how do you describe nimbostratus clouds

Answer 6

have a thick dark grey layer, can be 5000m thick with steady rain

Question 7

how does an anvils head form

Answer 7

at tropopause it spreads as it is less dense than air mass above

Question 8

what does precipitation need to be to precipitate out the clouds

Answer 8

heavy enough to fall through rising air currents

Question 9

what is the collision theory

Answer 9

different sized water droplets fall at different speeds and carried differently in rising air currents and randomly collide to form larger droplets

Question 10

what are the 3 different subcategories in the collision theory

Answer 10

1) coalescence- 2x h20 collide
2)aggregation- 2x ice crystals
3)accretion- ice crystals collect h20

Question 11

what is the Bergeron-finaleson theory

Answer 11

nuclei contacts with pure water that’s super cool and instantly freezes
