In 1910 an Arctic explorer by the name of Alfred Wegener coined the term continental drift. Wegener saw the same fossils in South America that he had seen in western Africa, and he proposed that the two continents had been connected at one time. Wegener’s proposal was ridiculed by the scientists of that day who saw the Earth’s crust as too solid to allow any model of that kind to work.
Over the years studies of earthquake epicenters have shown that there is movement of huge slabs of rock called tectonic plates. The rock material bends more and more steeply until the slabs eventually melt into the mantle–the molten interior of the earth. These slabs and everything on them do in fact move.
In 1952 an ocean cartographer by the name of Marie Tharp began making profiles of the Atlantic Ocean floor going from west to east. Her profiles showed a ridge down the center of the Atlantic with younger material in the center and older material on both sides. She proposed that molten material was coming up from the mantle and pushing the two slabs of ocean floor material away from each other. Where the slabs hit the edges of the continent, the material is deflected downward making trenches in the floor of the ocean.
All of these discoveries flew in the face of the accepted geological theory at the time, and Tharp was ridiculed. In time scientists came to understand that the Earth is made up of plates sliding along the surface and sliding down into the mantle when a continent is reached.
There is a message in all of this that what is considered to be scientifically impossible, sometimes turns out to be true. At the same time, a pet theory can ultimately be proven incorrect. One of the beauties of science is that eventually it cleans up its own mistakes.
Another message is that sometimes God addresses a problem long before humans know there is a problem. This whole process is one of the greatest recycling systems of all time. As nutrients and minerals get eroded off the continents, they are deposited on the ocean floor. The movement of the ocean floor ultimately returns this material to the mantle to be recycled back to the Earth’s surface.
No elements are lost from the Earth’s reservoir by this system, and it assures us that there is no waste in the resources of the planet as a whole. Jeremiah 10:12 speaks of God preserving the Earth by His wisdom, and continental drift is one of tools by which He does that.
