Why is plate tectonics a better concept than continental drift?
Plate tectonics is a better description of what's really going on.

In continental drift, the continents are drifting around like giant rocky icebergs cruising through a fluid like water. Only - there is no fluid to cruise through. The continents are moving through rock, not the ocean. Get a mental image of the Earth with the water stripped away. For this point, the water isn't important to consider. Then imagine the taller continents embedded in solid rock at their base, their keels extending below the ground, just like boats in water. Does it seem possible that these continental floaters can move through rock? Geophysicists thought it wasn't possible. But the matching continents seem irrefutable evidence that continents moved.

The continents can move, but not in the way of continental drift envisions. In plate tectonics, the continents move because they are part of entire slabe of the Earth's surface that move. A plate doesn't move by cutting a path through water or rock. It moves when ... more like a
