Anatomist and self-educated geologist Nicolaus Steno, 1673.

Wegener knew that this was impossible! Although Wegener's evidence was correct, most geologists at the time rejected his hypothesis of continental drift.

What is the force that moves the continents? What is continental drift theory explain? Glossopteris ferns had very heavy seeds that could not move by wind or drift on ocean currents. These are the rocks that can incorporate bones, shells, and exoskeletons from living organisms such as shells that are compacted sea creatures. To determine the relative In other words, although the magnetite crystals were pointing to the magnetic north pole, the location of the pole seemed to wander. However, convectional currents are the general thought for the motion.

One of the biggest clues that we knew it exists is because of the fossils we have uncovered today. strategy, but if this is new to you, here is some extra information. Several types of evidence supported Hesss theory of sea-floor spreading: eruptions of molten material, magnetic stripes in the rock of the ocean floor, and the ages of the rocks themselves. General appearance and typical dimensions of muscle fibers. What was the first evidence of plate motion?
