Chapter 10 Assessments.
Section 1
1. Other scientists questioned his theory because he could not explain exactly what happened. Also, he did not have proof of what happened.
2. When they found traces of tropical plants in Antarctica he told them there was no way tropical plants could grow in that climate. Which he thought proved Antarctica must have drifted from a warmer climate.
3. If the continents all connected then the rock patterns should be the same where the continents fit together.
4. Fossils were like the rocks, if they found a trace of one fossil somewhere and a trace of the same fossil across the world that would be a clue the continents were once connected because dinosaurs could not have swam that far.

Section 2
1. Types of rocks.
2. The rocks near the tectonic plates are younger because they just broke off.
3. The less dense materials of the ocean rise.
4. The heat causes them to rise.

Section 3
1. The move past each other.
2. Oceanic crust is formed by magma that seeps to the ocean floor.
3. The plates moving together, the plates sliding on top of each other, and the tectonic plates rubbing together.
4. Both occur in the mantle.
