Question 11

A subduction zone creates a __________ and __________.

Accepted Answer

trench; volcanoes

Question 12

What causes sea-floor spreading?

Accepted Answer

new oceanic lithosphere forms as magma rises to the surface

Question 13

What is the difference in how volcanoes and mountains are formed?

Accepted Answer

Volcanoes are formed from subducted plates
