Mo11-L3a Types of Plate Boundaries

KEY CONCEPTS:
1. What is Plate Tectonics?
2. What are the three types of Plate Boundaries? Transform Plate Boundary
the boundary between two plates that slide past
each other.
Vocabulary A-Z

Let us learn some vocabulary

Plate Tectonics
theory that Earth’s surface is broken into large, rigid
pieces that move with respect to each other.

Convergent Plate Boundary
the boundary between two plates that move toward
each other.

Lithosphere Subduction
the rigid outermost layer of Earth that includes the the process that occurs when one tectonic plate
uppermost mantle and crust. moves under another tectonic plate.
