Divergent Boundary Checkpoint

Alfred Wegener hypothesized that Earth’s continents had once been a single, large continent. Which data was Wegener unable to collect because of limited technology at the time of his studies?

• Similar rocks in similar structures are found on different continents across Earth.

• The facing coastlines of adjacent continents fit together like puzzle pieces.

• The same fossils are found on continents separated by oceans

• The ages of deep-ocean rocks indicate seafloor spreading at the Mid-Atlantic Ridge.

The evidence from the rocks that indicates that the plates are moving apart at this location is that–

• the rocks are older the farther they are from the center.

• there is a thickening of the crust where the two sides meet.

• the rock types on one side are very different from those on the other.

• one rock layer melts as it moves under the other side.
