boundary Flashcards
Constructive boundary
A constructive plate boundary occurs when two plates move away from each other.
magma comes out the top
Destructive plate boundary
A destructive plate boundary occurs when an oceanic plate is forced under (or subducts) a continental plate.
this forces magma to shot out
Conservative plate boundary
A conservative plate boundary occurs when two plates slide past each other.
collision boundary
A destructive plate boundary occurs when an continental plate is forced under (or subducts) a continental plate.

Tectonic Plate
Earth’s lithosphere is divided into large pieces called tectonic plates. These plates are in constant motion, and interactions at their boundaries can lead to natural hazards such as earthquakes, volcanic eruptions, and tsunamis.
