Plate boundary facts for kids
- Further information: Plate tectonics
The major types of plate boundaries are:
- Spreading boundaries. Mid-Atlantic Ridge and Africa's Great Rift Valley are examples. Rift valleys, mountains (orogeny), volcanoes.
- Collision boundaries. These collide, forming a subduction zone (West coast of the Americas) or a continental collision (India with Asia). Mountains (orogeny), valleys, volcanoes.
- Transform or fault boundaries. Here plates grind past each other along transform faults. Earthquakes, volcanoes,
- Conservative boundaries: little or no relative motion
All boundaries except the conservative ones are sites of major geological activity. We have plate boundaries on the earth.

Plate motion based on Global Positioning System (GPS) satellite data from NASA JPL. Each red dot is a measuring point and vectors show direction and magnitude of motion.
Global earthquake epicenters, 1963–1998. Most earthquakes occur in narrow belts that correspond to the locations of lithospheric plate boundaries.
