    • Question: Why are the continents drifting?
    • This is a plate. This is a plate.Answer: Plate tectonics
    • This is a plate. This is a plate.plate = landtectonics = building or moving

    • How do the plates move?
    • Earthquakes happen between the plates.1. Plates slide past each other.
    • Example: The San Andreas Fault in California
    • Volcanoes erupt between the plates under the ocean. The ocean floor bigger.2. Plates separate from each other.
    • Example: This Rift Valley in East Africa
    • Crashing plates make mountains. 3. Plates crash into each other.http://www.divediscover.whoi.edu/tectonics/tectonics-collide.html
    • 3. Example: Mountains in Peru, South America
