Plate Boundaries By: Miss Shrestha & Miss Morris
Plate Boundaries • Sliding Boundaries • Convergent Boundaries • Divergent Boundaries
Plates sliding sideways against each other. Plates rubbing together form earthquakes. Example: San Andreas Fault in California. Sliding Boundaries
Convergent Boundaries • Plates pushing together. • Plates pushing or colliding together form earthquake and volcanoes.
Convergent Boundaries • Plates push together to form mountains. • Example: Rocky and Himalayas Mountains. • When continental and oceanic plates collide the thinner plate slides under the other plate. This is called subduction.
Divergent Boundaries • Plates pulling apart. • Plates separate to form volcanoes and minor earthquakes. • Example: Mid Atlantic ridge

Mountain Building • New mountains form when plates pull apart magma push out from below and the lava cools and turns to rock.
Mountain Building • When plates push together, one plate is pushed beneath the other one, and this creates mountains. Visit the following website: http://www.classzone.com/books/earth_science/terc/content/visualizations/es1105/es1105page01.cfm?chapter_no=visualization
Fault Block Mountains • Form when masses of rock move upor down along a fault.
Folded Mountains • Form when two tectonic plates collide.
Dome Mountains • Form when the surface is lifted up by magma, forming a bulge.
