Plates on the Move A guide to plate boundaries and their movement

There are three types of plate boundaries/movement

1. Divergent (Dividing) Also known as seafloor spreading Plates are separating from each other as a new land mass forms This is seen at mid-ocean ridges and rifts Plate separation is a slow process. It widens at only about 2 centimeters per year. Picture from Author Hobart M. King

2. Convergent PART 1 Two continental plates collide. & crumple the edges of the plates & form mountains. This is uplift or mountain building. Volcanoes can form also. We can see the end result of the collision between the Indian & Eurasian plates which are the Himalayan Mountains. Picture from Author Hobart M. Kingwww.geology.com Picture from USGS

PART 2 When an oceanic plate goes underneath or is sinking under a continental plate it is called subduction. (Remembering Trick) cookie example colliding convergent All start with co cococo Picture from Author Hobart M. Kingwww.geology.com Convergent Movement

3. Transform Two plates slide past each other –Example: San Andreas Fault in California Picture from Author Hobart M. King
