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

2 There are three types of plate boundaries/movement

3 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 www.geology.comwww.geology.com Author Hobart M. King

4 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 www.geology.com Author Hobart M. Kingwww.geology.com Picture from USGS

5 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 www.geology.com Author Hobart M. Kingwww.geology.com Convergent Movement

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