4.1 Plate Tectonics

Question 1

Divergent Boundary

Answer 1

Two plates pull apart, magma surfaces: seafloor spreading, rift valleys, volcanoes, earthquakes

Question 2

Transform Boundary

Answer 2

Two plates slide along each other, creating strike/slip faults and earthquakes, releasing stored energy

Question 3

Convergent Boundary

Answer 3

Two plates crash together, crust breaks and folds upwards; causing mountains, island arcs, earthquakes, and volcanoes

Question 4

Core

Answer 4

A solid inner core of iron surrounded by molten (liquid) iron

Question 5

Mantle

Answer 5

less dense, elastic rock

Question 6

Crust

Answer 6

the thin, brittle, outer layer of rock
