Boundaries of the Earth


Convergent Boundaries

Ocean to Ocean: Creates a trench or mid ocean ridge.

Ocean to Continental: volcanic activity and mountains rise on the continental plate.

Continental to Continental: the land rises upwards and may cause volcanic activity.

Three Types of Convergent Boundaries : Plate Tectonics

Divergent Plate Boundaries

Ridge: When two ocean plates pull apart from each other they create a ridge with a trench in the middle from which Magma escapes.

Rift: in a rift valley the two plates have pulled apart and the area of land in between drops and is prone to fissure eruptions.
