17
Q

Substance from sea infl. Temp:
A) in summer oceanic climate…
B) in winter…

A

A)takes longer to heat because adjacent air layer is cool.

Cool air blows over CT resulting in moderate air temps

18
Q

B) in winter..

A

B) ocean gives off heat gained from sun, therefore adjacent air is relatively warm.
Therefore warm air blows over CT keeping temps mild in winter

19
Q

Inland places…

A

Do not experience moderating effects of ocean

Therefore have a large temp range (continental climate)

20
Q

Latitude

A

Further S/N from the equator you move the lower the temperature (suns rays strike earth obliquely therefore larger area being heated less intense let therefore lower temp recorded)

21
Q

Altitude

A

Higher you go the temp decreases
Density of atmosphere decreases with altitude
Therefore fewer gas molecules absorb earths LWTR

22
Q

What does LWTR stand for

A

Long wave terrestrial Ray

23
Q

Distance from sea:

A

Closer to the sea- SMALLER TEMP RANGE therefore these places receive moderating infl of sea
Places further from sea-LARGE TEMP RANGE bcuz summer & winter not moderated by sea

24
Q

Precipitation:

A

Water in its solid/liquid form falling from clouds

25
Q

Evaporation:

A

When heat applied to water it changes state to a gas then water vapor

26
Q

Condensation:

A

As water vapor rises, must reach height where it is cool enough. Water vapor turns back to water

27
Q

Dew point temperature:

A

Temp water needs to reach before it is cool enough to condense

28
Q

Evapotranspiration:

A

I release of water vapor from plants and trees

29
Q

What rainfall does cape town recieve?

A

Frontal

30
Q

What is an isohyet

A

Line on map joining all places that recieve equal rainfall

31
Q

Biome:

A

Determined by temp/rainfall
Large ecological are of earths surface
Contains fauna and flora
Adapting their environment

32
Q

Biodiversity:

A

Within biome
Variety of diff types of life (animal life) found on earth
Measure of variety of organisms present in diff ecosystems

33
Q

link between climate and biome

A

Increase temp + increase rainfall = densely vegetated biome e.g forest
Decrease temp + decrease rainfall = sparsely vegetated biome

34
Q

Fynbos:
A)climate
B)fauna
C) flora

A

A)Mediterranean
B) grysbok, several tortoise
C) proteas, shale

35
Q

Desert:
A)
B)
C)

A

A) varied
B) insects, snakes
C) cactus, elephant tree

36
Q

Karoo:
A)
B)
C)

A

A) summer rain winter drought
B) monkey beetles, mongoose
C) succulents

37
Q

Subtropical:
A)
B)
C)

A

A) humid/dry
B) crocodile, lion
C) chir pine, tree ferns

38
Q

Grasslands:
A)
B)
C)

A

A) hot wet summers, cool dry winters
B) gazelles, giraffe
C) prairie rose, acacia tree

39
Q

Producers:

A

Organisms in an ecosystem- provide biomass from inorganic compounds

40
Q

Consumers:

A

Organism of an ecological food chain that reviews energy by consuming other organisms

41
Q

Give definition:

Weather:

A

State of atmosphere at any given time or place
