﻿ The Four Types of Plate Boundaries

1. Subduction - occurs when one plate slides under another. Ex: Mt. St. Helens, Mt. Rainer, Crater Lake, Mt. Hood  2. Spreading - occurs when two plates move apart Ex: Mid-Ocean Ridge Ridge, Sea Spreading  3. Continental Collision - occurs when two continents collide. Ex: Himilayas

4. Sliding - a.k.a.lateral boundary Ex: San Andreas Fault, CA
