Higher end of Stratosphere

7

When flying, above which altitude does one need supplemental oxygen?

Above 10,000 ft

8

Composition of air:

78% Nitrogen 21% Oxygen 1% Argon The rest is carbon dioxide, hydrogen and other rare gases.

9

Cirrocumulus

--Above 18,000 ft --Small dots

10

--Above 18,000 ft --Palm tree tops

11

Altocumulus

--6,000 ft to 20,000 ft --Large dots

12

Altostratus

--6,000 ft to 20,000 ft --Flat with spikey edges

13

Cumulonimbus

---Near ground to 50,000 ft --Messy stack

14

Cumulus

--Below 6,000 ft --Tidy stack

15

Stratus

--Below 6,000 ft --flat, long

16

Stratocumulus

--Below 6,000 ft --Long with puffy tops

17

Cumulus, from Latin to English

A heap, e.g. a heap of cotton balls.

18

Stratus, from Latin to English

A covering or blanket.

19

Cirrus, from Latin to English

A curl, e.g. curls of white hair.

20

The whitest, highest clouds. They're made of tiny ice crystals.

--Cirrus --18,000 ft or higher)

21

High level clouds

--20,000 ft plus --Below freezing, made of ice crystals --Cirrus, cirrocumulus, cirrostratus

22

Middle level clouds

--6,500 ft plus --Altocumulus, altostratus, nimbostratus

23

Low level clouds

--Base below 6,000 ft --Stratocumulus, stratus, cumulus, nimbostratus

24

Towering, vertically rising clouds

Cumulonimbus and Towering Cumulus

25

Land breeze

In PM, land cools faster than water, causing land's air to go out to sea.

26

Sea breeze

During day, land is warmer than water, causing its air to move up and in a circular motion toward the sea and back onto land.

27

Thunderstorm's cumulus stage:

Warm air rises in the cumulus clouds

28

Thunderstorm's mature stage:

Precipitation begins, typically last 20-40 minutes

29

Thunderstorm's dissipating stage:

--Downdrafts of cold air overcome rising warm air, and --the temp in the clouds warms to match that of surrounding environment
