Continental drift is to plate tectonics:

what the old concept of atoms as tiny solar systems is to the modern view of atoms.Or what Darwin’s vision of evolution was to the modern viewA Model-T Ford to a modern carA Wright Flyer to a modern jetlinerThe Army of the Potomac to the modern U.S. ArmyIn other words, an early prototype.

Wegener successfully reassembled the continents, and made remarkably astute estimates of when they separated and how they moved, but he had no data on the oceans. The theory was called “continental drift” because the central element was the movements of the continents. Besides, we live on the continents, so they must be the important parts, right? Several things happened to change that.

World War II saw the development of sonar and sensitive magnetometers for probing the oceans, in this case, looking for submarines. Geoscientists like Harry Hess spent the war salivating over what they could do with this gear once the war was over.Studies of earth’s magnetic field led to the discovery that the apparent positions of the poles had changed (actually the continents moved) and that the field underwent occasional reversals.The Worldwide Standardized Seismic Network, originally developed for monitoring nuclear tests, showed that earthquakes were highly localized in narrow zones surrounding relatively aseismic regions, called “plates.” The continents are generally within the plates. All the action is in the oceans. The continents merely ride passively.

Since the plates, not the continents, are the active elements, we now call the theory “plate tectonics.”

Have a awesome day❤️✨

The theory of continental drift suggests that all the land masses on earth were once part of one supercontinent. Plate tectonics is the ability to measure the movement of land masses.

Answer from: Quest

relative dating involves things like higher layers are most recent than rocks lower in the sequence. this can be extended to the known sequence of fossils. rocks containing rabbit fossils are later than those containing dinosaur fossils.

absolute dating methods mainly use radioactive elements that have known rates of decay and produce recognizable products. for example potassium 40 decays to produce argon. once a rock has solidified the argon is trapped. by measuring the argon and potassium0 you can get an accurate number for the age.

some other methods are good for archaeological ages. dendrochronology involves recognizing the sequence of tree rings. the orientation of magnetized particles in baked clay can be used to date a fire.

hope this .. .
