Q

Processes/steps of the water cycles?

A

step 1 - precipitation
step 2 - transfer and storage - surface run off, infiltrationa and perlocation, lakes, dams, rivers
step 3 - river flows out to sea

Q

What is a steep catchment

A

very little water retained
groundwater recharge is minimal
large water volume
moves out quickly

Q

What is a flat catchment

A

surface water retained seeps into soil to be groundwater causing water tables to be shallower
small volume of water moves out slowly after rainfall

Q

6 reasons unlimited water isn’t avalible for everyone

A

1) landlocked
2) no permeable surfaces for groundwater
3) no river systems
4) desert

25
80% of the earth's freshwater is
surface water
26
surface water can be replenished by
rain
27
positives of surface water
cheap, easy access, dams protect from floods
28
negatives of surface water
easy contamination, treatment for pollution is expensive dams can cause floods
29
steps of taking the salt our of water
- suck in seawater - clean - reverse osmosis - final cleaning
30
positive of desalination water
we won'y run out
31
negative of desalinated water
expensive, leftover salt could wreck nearby ocean
32
groundwater is
water under the surface
33
how does groundwater work
- water sinks through gaps betweeb sediment, soil/sand/gravel - hits something hard - fills gaps - we dig bores to pump water out
34
positives and negatives of groundwater
cheap easy can be dug close to wherever needed clean - hard to contaminate long time to replenish
35
all water is really
recycled water
36
positives of recycled water
smart and quick renewable
37
negatives of recycled water
if cleanibg doesnt work people get sick idea is gross politicians lose votes
38
factors that influence water flows and the avalibility of water resources in different palces
latitude altitude topography location climate change
39
Latitude affect on water flows and resources
because the earth is round and it tilts back and forth towards the sun, the pokles distance will affect climate
40
more radiation
hotter
41
less radiation
colder
42
Altitude: how high an area is will also affect
water avalibility
43
tropic of cancer
up
44
Location - landlocked will afeect
water avalibility
45
topography
weather and climate patterns influence evaporation rates as does the shape. - water avalibility
46
more heat - more evaporation
dry land - droughts
47
more heat - glaciers melt
less freshwater
48
more heat - ice caos melt
sea levels rise - floods
49
different parts of aus get more rain than otheres
tully most rain
50
not alll aussie land has
unlimited access to water
51
wiyout rain, lakes, river and aquifers can't be
replenished
52
city uses drains
as groundwater bores
53
In scale : means
represents
54
1cm on a map means
25000 cm on land if 1:25000
55
how to measure a straight line distnace
1) measure in cm 2) check the scale 3) if !:25000 times by 25000

What is a contour interval
the differnece in elevation represented by each contour line on a toppgraphic map
70
Contour lines
lines on a map that join places of the smae height
71
relief
is the term used fro the differences in height from place to plaace on the surface - height difference
72
PQE
PATTERN, QUANTIFY, EXCEPTIONS
73
PATTERN
general overview of any patterns you can see. e.g. forest seems to be located in northa nd west africa
74
QUANTIFY
use statistics e.g. 240.3 million hectares of forest in central africa
75
EXCEPTIONS
what doesn't fit e.g. however ther are also forets regions located in south and east africa too
