Plate Tectonics

Below is a picture of sea-floor spreading. How are the ocean crusts moving?

• Converging

• Diverging

• Sliding

• No movement

Wegener’s proposal of a supercontinent was supported by:

• earthquake data
• seafloor magnetism
• rock, fossil, and climate data.
• convection currents in the mantle.
