quick fix Flashcards
Rain gauch
- Collecting jar with funnel
- Water poured into measuring
- Put out in open area
- Not sheltered by buildings, trees
- Buried in grass
- Take measurement every 24h
Stevenson screen:
white —> reflect sunlights, allow air to circulate easily
Place 1m above ground —>
In open space/ unsheltered form trees, buildings
Wood —> doesn’t conduct electricity
Statted —> allow easy air circulation
Double boảding —> prevent sun radiation
In shade —>measure temp of air
altitude
temp decrease one degree for every 100m
Hot desert hot? Explain
Rain shadow effect Distance from sea/ landlocked Cold ocean current Hadley cells wind direction angle of suns descending air(dry) air pressure
No condensation
No transpiration/ evaporation
Beach management
- Hard engineering: sea wall, gabians, grounds
- Soft engineering: beach nourishment, artificial reefs
- —> Improve public awareness and appreciation of sea resources
(e. g) main school board allows students to have “hands in” experience
Describe amazon rainforest climate
High rainfall all year Each hot day followed by heavy rainfall High humidity 2000mm of rain water or more Avr temp 30C High temp through out year No season
Explain amazon rainforest climate
low atmospheric pressure Rising air large amt of evaporation Transpiration Condensation Convectional rainfall
Vegetation in desert
Scattered/sparese/ not much vegetation Scrubs/bushes Cacti Plant with spiky/narrow leaves Little variety of vegattion
rain shadow effects Sahara
The Atlas Mountains enhance the aridity of the northern part desert.
- major mountain ranges act as a barrier
- -> a strong rain shadow effect on the leeward side by dropping much of the humidity brought by atmospheric disturbances along the polar front which affects the surrounding Mediterranean climates.
Air is forced to rise over mountains, air cools and condensation occurs, rain falls over the mountains, dry air sinks down the other side of the mountain.
ITCZ and Sahara
the presence of the Intertropical Convergence Zone, ITCZ, in the southern Sahara Desert prevents moisture from reaching the area
cold ocean current
cool air and makes it harder to hold moisture.Most moisture falls as rain before it reaches the land
high pressure
creating cloud free conditions
Weather
Weather is how the atmosphere is behaving on a day to day basis
ecosystem
an area that contains organisms interacting with one and others and their physical environment
altitude in rainforest
suns ray are more concentrated at the equator as they hit the earth
prevailing winds
certain pattern of winds
- movement of wind starts of equators where its hottest
- oversea, winds pick up moisture
ocean current
- hot ocean current warms winter in coastal region
col ocean current cool summer in coastal region
- ocean heats up/ cool down slower than land
- -> bringing warmer climate/cooler climate
cold current: more dense/heavier
- make it harder to hold moisture
- moisture fall b4 get to land
warm current
- holds more moisture
- causes evaporation
latitude
distance form equator 1. temp drops further away from equator due to earth's curvance 2. closer to poles sunlights had to pass large SA of atmosphere --> more dispersed/ energy loss --> temp is lower
air pressure dessert
→warm air rises at equator, and cools
→ since cold air holds less water, precipitates at equator
→ dry air then moves N&S and get to N30 and get S30, sinks
*→ air is dry, no condensation→ no rain
rain shadow effect
→ hot rising air cools as approaches mountain(high altitude/ high temp)\
(as air is forced to rise over mountain
→ dry air sinks down other side of mountain
destructive
- plate slide toward each other
- one comes under
focus
where earthquake occur
epic centre
the point directly above focus
where earthquake occurs
seismic waves
a wave, vibration which travels within the earth
