Is the Earth Expanding? Are there problems with the Plate Tectonics theory?

The continents fit together in both the Atlantic ocean and the Pacific as well.

Did you know that the oldest rocks on the planet date back to about 4 billion years ago, but all of those rocks on land.

On the ocean floor, the rocks have only been dated to less than 200 million years.

Something is wrong with the accepted theory of plate tectonics. I remember when I was in elementary school the idea itself was not in all of the textbooks and was only hinted at but not fully accepted by our teachers.
