Divergent Boundary Lab 2.7.12
Part 8: In the Sea and on Land
1. Describe what occurs during seafloor spreading.
Magma comes up through ridges on the ocean floor. It moves across the bottom of the ocean, hardening, then sinks down into trenches. The hardened magma then melts and the process begins again.
2. Draw in arrows to indicate the direction of movement at the Mid-Ocean Ridge and at the African Rift Valley below.
