Seas & PeninsulasSeas & Peninsulas• Arabian Peninsula
– Separated from Africa by Gulf of Aden & Red Sea
– Sinai Pen. & Suez Canal separate the land to the north/west
– Persian Gulf is on the east side
Gulf of Aden
Seas & PeninsulasSeas & Peninsulas• Anatolia Pen.
–Black Sea to N–Aegean Sea to
W–Mediterranean
Sea to S–Many straits
connecting seas ($$)
Aegean Sea ANATOLIA
Bosporus Strait
Dardenelles
Bosporus Strait
Seas & PeninsulasSeas & Peninsulas• Strait of Gibraltar
–Separates Africa from Iberian Pen.
–Only a dozen
miles or so
wide• ‘gateway to
Africa’
Strait of GibraltarStrait of Gibraltar
Seas & PeninsulasSeas & Peninsulas• Dead Sea
– On Jordan River (border w/ Israel)
– 8X saltier than any ocean- How come?
– In the 50s• L= 262 m, W= 57 m
– Today• L= 42 m, W= 11 m

Seas & PeninsulasSeas & Peninsulas• Caspian Sea
–Largest inland/landlocked body of water (lake)
–But it is salt water!! (remnants of larger sea)
–Facing evaporation increases, decrease in flow from feeder rivers, and increase in irrigation/industry uses
Seas & PeninsulasSeas & Peninsulas• Aral Sea
– Use to be lg & have productive fishing
– Shrunk drastically due to USSR draining it for irrigation
– Ppl build sm. dams to create basins of freshwater from rivers
RiversRivers• Nile River
–Longest in world
–Flows NORTH to Med. Sea
–90% of Egyptians live in delta or along river (= 3% of land)
–Faces great flood seasons built Aswan High Dam for control

“Longest River in the World”

RiversRivers• Tigris & Euphrates
–Mesopotamia or ‘land b/w two rivers’; aka Fertile Crescent
–Join to form Shatt al Arab• Border of Iraq &
Iran
• Wars & treaties
over it
RiversRivers
• Wadis- dry streambeds that will fill with heavy rain flash floods (seasonal)–Since they are typically arid, creates
mud quickly dangerous mud flows
Wadi in Oman
Wadis – Instant Springs
Plains, Plateaus, & Plains, Plateaus, & Mtns.Mtns.• Since most is desert/steppe agricultural
base = coastal areas of Med. Sea, Caspian Sea, & Persian Gulf
• Atlas Mtns– Longest mtn
range• Stretches from
Morocco to Algeria
– Northern side of Atlas allows for lots of agric. (farms, fishing, livestock)• Rainy side, Med. climate
Plains, Plateaus, & Plains, Plateaus, & Mtns.Mtns.• Hejaz & Asir
–West coast of Arabian Pen.–Rainshadow effect to Central Plateau
• Caucasus Mtns–b/w Black & Caspian Sea–Seen as border b/w

Tectonic ActivityTectonic Activity• Meeting point of the African,
Arabian, & Eurasian plates–Reason for mountainous terrain–Many earthquakes
• Turkey 1999• Iran has 90% of land on faults
–Landforms still Δing• Red Sea
Natural ResourcesNatural Resources• Oil (petroleum) & nat. gas are region’s
most abundant resources–70% of world’s oil
–33% of world’s nat. gas• Reserves are still being discovered!
–WWII sparked production as we moved to modern industry/reliance
