Inner core
Iron. 3870° 2400km diameter
1 of 12
Outer core
Molten iron. 2220km thick
2 of 12
Mantle
Magma 2850km thick
3 of 12
Crust
sand and rock 5-50km thick
4 of 12
asthenosphere
flexible like plastic. 100-200km below surface
5 of 12
lithosphere
cooler, solid, brittle. 100km below surface
6 of 12
oceanic&continental crust
oceanic denser (3g/cm3) continental (2.6g/cm3)
7 of 12
Divergent ( constructive)
Iceland, Mid Atlantic Ridge. Eurasian moving away from Caribbean at 4cm a year causing volcanoes.
8 of 12
Convergent (destructive) - Oceanic vs Oceanic
Montserrat volcano. SA plate moving W meeting the Caribbean plate. SA plate subducts. Line of subduction marked by the Peurto Rico Trench
9 of 12
Convergent (destructive) - Oceanic vs Continental
Indian ocean tsunami. The Indian plate subducts beneath the Burma plate. plates slipped around 15km . Indian plate moving E at 6cm a year creating sunda Trench.
10 of 12
Convergent (destructive) - Continental vs Continental
Nepal, Himalayas. Indian crashing into Eurasian at 5cm a year
11 of 12
Conservative
Izmit Turkey. Eurasian and Abraian plate causing Anatolian fault. San Andreas Fault where Pacific& NA are both moving N but Pacific is moving quicker.
