I believe the correct answer is C. the continents have moved in the past and are still moving
We have several layers of crust but they separated because of the desity level differences. The lighter material cruet layers rose upwards and the heavier materials caused them to drop further down
The creators of the theory could not find a way to answer the question "What force was strong enough to move them?". Another reason why was that they proposed a movement speed of the continents that was incredibly high and impossible to reach.
Answer:
When two plates are moving away from each other, we call this a divergent plate boundary. This is known as a transform plate boundary. As the plates rub against each other, huge stresses can cause portions of the rock to break, resulting in earthquakes. Places where these breaks occur are called faults.
