difference between the continental drift theory and Plate tectonic
Answers
Answer:
two types of plates—oceanic and continental—which float on the surface of the Earth’s mantle, diverging, converging, or sliding against one another. When two plates diverge, magma from the mantle wells up and cools, forming new crust; when convergence occurs, one plate descends—i.e., is subducted—below the other and crust is resorbedA continental plate is exemplified by the North American Plate, which includes North America as well as the oceanic crust between it and a portion of the Mid-Atlantic Ridge. The latter is an enormous submarine mountain chain that extends down the axis of the Atlantic basin,…When continental plates collide, the edge of one plate is thrust onto that of the other. The rocks in the lower slab undergo changes in their mineral content in response to heat and pressure and will probably become exposed at the surface again some timescientific idea that was initially ridiculed paved the way for the theory of plate tectonics, which explains how Earth’s continents move.Bachendri Pal is an Indian mountaineer, who in 1984 became the first Indian woman to reach the summit of Mount Everest.
