Continents fit together like a puzzle. The exact same rock sequences were found in Africa and South America. Evidence of glaciers was found in Africa. There are mountains in the middle of the ocean floor. The age of the ocean floor is younger than the continents. In the middle of the ocean floor, the rock is younger than the areas further away. Trenches are formed in the oceans near the continents. The sea floor spreads apart from the mid ocean ridge moving away from each other; magma rises creating new ocean floor which pushes the older floor away causing continents to move. Is continental drift still happening? Are continents made of the same type of rock? How fast do the plates move? Can bigger plates break apart to make smaller plates? Why is the ocean not getting bigger if new rock is being added to the ocean floor? When sea floor spreads, does this create mountains? Do all plates separate at boundaries?
