Plate tectonics

Question 1

Lithosphere

Answer 1

Crust + solid upper mantle

Question 2

Athenosphere

Answer 2

Semi-molten magma, heavier + falls back down to the lower mantle -> convection currents

Question 3

Continental drift

Answer 3

The theory that the Earth’s plates are
constantly moving due to convention
currents and endogenic forces

Question 4

Who proposed continental drift

Answer 4

Alfred Wegner

Question 5

Continental fit

Answer 5

Theory that the continents fit -> Pangea

Question 6

Continental fit - proof

Answer 6

rocks + fossils in the same
strata + matching fold mountains eg. Scottish highlands + Appalachians

Question 7

Convection currents

Answer 7

Magma heated in the mantle rises towards the lithosphere, cools, becomes semi molten (athenosphere), moves sideways + sinks. Sideways movement causes movement cause movement of the plates

Question 8

Endogenic forces

Answer 8

Cause the crust to move
Are caused my convection currents
