Geography 6 – Lecture 6 Notes – Europe, North Africa, and the Mideast Midterm grades will be posted online If you get an A or A- can do a paper instead of a final exam EURASIA Eurasia most populous continent- 6x more pop than 2 nd most populous continent- Africa Responsible for impt dvlpmts: alphabet, gunpowder, iron tools, paper, industrial revolution, elected govts Asia big for California b/c we face it across Pacific- but more familiar w/Europe? So focus on Eurasia as a whole Eurasia largest continent; only continent w/a pronounced E-W axis, narrow from N-S (opp of other continents eg N America)- responsible for spread of technology E-W across Eurasia Central Asian Steppe- grasslands?- impt part of Asian history for nomads (Huns, Mongols etc.) who invaded/conquered other ppl… W Eurasia- prime feature: huge inland sea- the Mediterranean Sea- world’s largest inland sea; land around it has MDN climate (same as So Cal)- wet cool winters and dry hot summers; also M-pDN climates on W side of all the other continents (incl W side of Eurasia; Chile; etc…) MDN zone of MDN Sea more extreme MDN climate b/c extends far into ocean? (temps not moderated by ocean breezes), goes up to high elevation, is so big & covers wide range of elevations- has greatest # of plant/animal species than any of the other MDN zones- so there’s been strong selection for cereals, legumes etc w/big seeds so they can survive thru more extreme climates These big seeds useful to humans- peas, lentils, chick peas, wheat, barley etc. MDN zone of W Eurasia incl all land surrounding MDN zone, eg. some African countries (Nigeria? Etc); to some extent Egypt N, S America/Africa/Australia etc. no islands visible – but Eurasia ~only continent fr which islands visible – in SE Asia & Europe (across channel from France = England, Ireland; MDN full of moderate-sized islands incl Corsica) – allowed boats, seafaring to develop here earliest & become the best; ppl doing this by 10,000 BC Glaciation- both N America, Eurasia had ice sheets b/c of big zone in Arctic that generates ice; Europe has high alps which are glaciated; so many glaciers moving back and forth, grinding up the soils in Eurasia In N America, plants/animals could move N/S, relocate/survive- but in Eurasia esp. Europe, as plants/animals moved S (fr Scandinavian ice sheet?) bumped up against another (Alpine) ice sheet, didn’t survive- Europe has ~300??x less tree species than N America for this reason Coastline- is it smooth or indented (coarse)?; N America ~smooth; Africa, AUS, China ~smooth; but Europe’s coast widely indented w/big peninsulas- big one= Scandinavian peninsula- broken into Finnish peninsula & others; Peninsulas allow for the people living there to become a separate state from rest of landmass/continent- eg. Italy, Greece, Denmark etc- all became their own countries w/own states,
