Was ist der Unterschied zwischen der Geburtenrate und der Fertilitätsrate?
Geburtenrate: Zahl der Geburten/1000 Einwohner
Fertilitätsrate: Anzahl der Kinder/Frau (Österreich: 1,4)
Was sind Ursachen für Hungersnot in Afrika?
- Bevölkerungswachstum
- Armut
- Wassermangel
Was sind die Wegbereiter für Dürrekatastrophen?
- Bevölkerungszuwachs
- Überweidung, denn Anbau kaum möglich
- Abholzen des wenigen Holzes fürs Kochen
- Ausbeutung der Grundwasservorräte
- Intensive Landwirtschaft
- Klimaerwärmung
Welche zwei Typen von Oasen gibt es?
- Grundwasseroasen/ground water oasis
- Flussoasen/river oasis
Wie kann es in in der Sahara einen Grundwasserspiegel geben, wenn es dort kaum bis nie regnet?
Als in Europa die Eiszeit herrschte, gab es eine Regenperiode in Afrika und Wandmalereien in der Sahara beweisen, dass es dort einmal eine Savanne gab (Desertifikation).
Wer lebt in den Oasen?
- sesshafte Ackerbauer: Dattelpalme-, Gemüse-, Obstanbau
- nicht-sesshafte Nomaden: Viehzucht (nicht sehr bedeutend in den Oasen
According to the location what types of deserts can be found?
- deserts close to the Tropic of Cancer/Capricorn e.g. Sahara, Arab Peninsula: they are in the rainshadow of mountain ranges
- deserts in coastal areas close to a cold ocean current e.g. Atacama desert (Chile), Namib desert (Namibia): cold water means no rainfall
- center/mid continenatal deserts e.g. Gobi desert (west of China): Himalaya mountains block rain from the Indian Ocean, Pacific Ocean too far away
According to the degree of mechanical weathering what types of deserts can be found?
- mountain desert (Gebirgswüste) e.g. Ayers Rock (Australia), Cappadocia (Turkey): mountain area with less than 250ml precipitation/year, no vegetation
- stony desert (Geröllwüste)
- sandy desert (Sandwüste)
What is mechanical wheatering?
Due to daily extremes of temperatures, the rock deteriorates. High up in mountains it is mostly found as frost shattering.
What type of desert is found most often mountain, stony or sandy desert?
Against belief the mountain desert is the most common, then the stony and the sandy desert is only one quarter of the word's deserts.
In the subtropical zone what climate and vegetation do you have?
close to the Mediterranean: Mediterrenean climate (Winterregenklima) - MM vegetation Macchie/-a
close to the Tropic of Cancer: desert climate - semi-desert, desert
Von wo bekommt der Nil sein Wasser?
Zwei Quellflüsse:
- aus dem Raum unter dem Viktoria See (tägliche Niederschläge)
- aus Äthiopien (einfache Regenzeit)
Wieso gibt es am Nil seit dem 19 Jhdt keine Überschwemmungen mehr?
Wegen dem Nasser Staudamm gibt es regelmäßige Wasserführung im ganzen Jahr und nicht mehr nur im Herbst.
Was hat der Staudamm im Nil für Auswirkungen?
- keine Überschwemmungen mehr
- gleichmäßige, ganzjährige Bewässerung
- ganzjähriger Anbau, mehrere Ernten/Jahr
- Steigung der landwirtschaftlichen Leistung
- Stromerzeugung (Industrialisierung)
- Massentourismus (Schiffe können verkehren: Kreuzfahrten)
Wo am Nil in Ägypten spricht man vom Tal der Könige?
Zwischen Assuan und Luxor, dort gibt es riesige Tempelanlagen. Oft Kreuzfahrten zwischen diesen Städten, aber auch in Hugada (am Roten Meer).
Name the Global zones from North to South:
Polar zone
Subpolar zone
Temperate zone
Subtropical zone
Tropical zone
At how many degrees are the Tropic of Cancer, the Mediterrenean and the Arctic Circle located?
Artic Circle: 66°n (between Temperate and Subpolar zone)
Mediterrenean: 40°n (between Temperate and Subtropical zone)
Tropic of Cancer: 23°n (between Tropical and Subtropical zone)
What is climate?
Climate is the average weather over a long period of time. e.g. Monsoon climate (raining season=summer)
What is weather?
Weather is the day-to-day condition of the atmosphere (weekly changing) in terms of temperature, rainfall, sunshine and wind.
What are the climatic factors?
temperature
precipitation
air pressure
wind
What factors affect temperature?
Distance from the equator (latitude)
Distance from the sea
Prevailing winds
Altitude
Why does the latitude (=distance from the Equator) affect the temperature?
Because places that are closer to the Equator are warmer than places near to the poles.
Why are places closer to the Equator warmer?
Because of
the curvature of the Earth: at the equator the heat is concentrated upon a small area, but due to the great curvature near the poles there is a larger area to heat up there
the angle of the sun in the sky: as the sun's rays pass through the atmosphere at a more direct angle (and therefore more quickly) at the Equator, less heat is lost
the layer of atmosphere that surrounds the Earth: the amtosphere contains dust, smoke and other solid particles that absorb heat
Why does the distance from the sea affect the temperature?
Because land and sea respond differently to temperture.
Land heats up quickly, but also loses heat quickly (summer and winter = large temperature range).
Sea heats up and cools down much more slowly (Atlantic ocean: 15,16,17°C, therefore small temperature range).
Name some countries far and close to the sea:
Far: Russia, Austria (therefore very cold winters and relatively warm summers)
Close: Britain, Ireland, France (summer remains rather cool and winter mild)
What are prevaling winds? In Austria?
The prevaling wind is the direction from which the wind is most likely to come.
In Austria and most Europe we are within the westerly wind zone, meaning it comes from the Atlantic ocean with a lot of humidity.
Why does the prevailing wind affect the temperature?
Because it has it's own temperature and it depends on:
where the wind comes from
type of surface over which it passes
Why does the altitude (=height of the land) affect the temperature?
Because as height increases, the air becomes less dense and so is less able to retain the heat it receives from the ground.
Mountains < temperature than lowlands
Decrease of 0,5°C/100m
Explain the relief rainfall (=Steigungsregen):
Air blows from the sea (prevailing westerly winds) - towards a mountain range - humid air forced to rise - the rising air cools - condenses into clouds - heavy rain = on the windward side (LUV-Seite)
air descends - warmed by the land - clouds disappear - rainshadow - little rain - dry air = leeward side (LEE-Seite)
Where does the humid air in Austria come from and where does the relief rainfall occur?
- from the Atlantic Ocean, Mediterranean sea, Adriatic sea
- Northern rims of the Alps
