The expanding Earth or growing Earth hypothesis argues that the position and relative movement of continents is due at least partially to the volume of Earth increasing. Conversely, geophysical global cooling was the hypothesis that various features could be explained by Earth contracting. Although it was suggested historically, since the recognition of plate tectonics during … WebbOceans cover slightly less than half of the Earth's surface. B) False. According to the nebular hypothesis, all of the bodies in the universe evolved from a rotating cloud of gases and dust about 5 billion years ago. B) False. Much of our modeling of Earth's interior comes from the study of seismic or earthquake waves.

WebbDeveloped from the 1950s through the 1970s, plate tectonics is the modern version of continental drift, a theory first proposed by scientist Alfred Wegener in 1912. Wegener didnt have an explanation for how continents could move around the planet, but researchers do now. Correspondingly, who discovered plate tectonics and continental drift?

The theory maintains that the crust and uppermost mantle, or lithosphere, is segmented into a number of solid, rigid slabs called lithospheric plates.
