| 4 types of plate movement | slip, spreading, collision, subduction |
| the crust floats on this layer | asthenosphere |
| divergent boundaries | Two plates tear apart or move apart from each other |
| two plates meet each other | convergent boundaries |
| one plate goes underneath the other | subduction zone |
| How did the scientists describe the shape of the lava rocks | pillow-shaped |
| Evidence to support that magma moves up through mid-ocean ridges and spreads sideways | age of rocks and magnetic reversal clues |
| Convergent Boundary: When Ocean plate collide with LESS-dense continental plate they form | forms volcanic mountain |
