Plate Boundaries
Plate Boundaries
• Definition: The edges of plates that meet at a line.
• There are three types of boundaries:
• Transform
• Divergent
• Convergent
Transform Boundary
• Place where two plates SLIDE past each other moving in opposite
directions.
• At this boundary, Earthquakes occur frequently.
• When two plates SLIDE!
Real Life Example:
Divergent Boundary
• When two plates move apart or diverge.
• When two plates SEPARATE.
• Geographic examples:
• Mid-Ocean Ridges (ocean-ocean)
• Rift Valley’s (continental-continental)
Real Life Example:
• Oceanic-Oceanic
• Mid Atlantic Ridge
• North American Plate- Eurasian Plate
• South American Plate- African Plate
• Crease a mid-ocean ridge
where new crust forms.
Real Life Example:
• Continental-Continental
• African Rift Valley
• African Plate and Arabian Plate
• Create a huge rift valley!
Convergent Boundary
• Place where two plates come together, or converge.
• When two plates COLLIDE.
• Create Subduction Zones
• Geographic examples:
• Mountains (continental-continental)
• Trenches and Volcano Mountains (continental-oceanic)
• Trenches and Island Arcs (oceanic-oceanic)
Real Life Example:
• Continental- Continental
• The Himalayan Mountains
• Eurasian Plate and Indian Plate
• Create Huge folded mountains!
Real Life Example:
• Continental-Oceanic
• The Cascade Mountain Range
• Juan de Fuca Plate and the North
American Plate
• Pacific Plate and Gorda Plate
• Create a line of volcanic mountains
Real Life Example:
• Oceanic-Oceanic
• Caribbean Island Arc
• Caribbean Plate and South American Plate
• Creates a line of Islands
Left Side:
• 1st Row: On each of the three tabs
• Front Side: Label the three types of boundaries.
• Back Side: Identify the different types of that
boundary (example: ocean-ocean).
Left Side:
• 2nd Row:
• Front Side: Use ONE word to describe the
movement of that boundary.
• Back Side: What type of geological features form
at that boundary?
Left Side:
• 3rd Row:
• Front Side: Draw a picture/Diagram of the plate
boundary/movement
• Back Side: Give the different real life examples of
that boundary.
