Passage Three The theory of plate tectonics describes the motions of the lithosphere, the comparatively rigid outer layer of the Earth that includes all the crust and part of the underlying mantle. The lithosphere is divided into a few dozen plates of various sizes and shapes, in general the ...
The theory of plate tectonics describes the motions for the lithosphere, the comparatively rigid outer layer of the Earth that includes all the crust and part of the underlying mantle. The lithosphere is divided into a few dozen plates of various sizes and shapes, in general the plates are in...
The Theory of Plate Tectonics The idea that continents moved during the past goes back to the time when people first noticed that the margins of eastern South America and western Africa looked as if…
According to the theory of plate tectonics, Earth's surface is composed of separate rocky plates. Answer Choices A Wegener's idea of continental drift explained several features of today's continents, but its mechanism was not understood until the theory of plate tectonics was developed. B The ...

from Chapter 9 / Lesson 1 44K Discover the pieces of the Earth's crust known as tectonic plates. Explore the layers of the Earth, how tectonic plates move by convection currents in the mantle, the Plate Tectonic theory, and the landforms created by...
Earth’s mantle convection, which facilitates planetary heat loss, is manifested at the surface as present-day plate tectonics1. When plate tectonics emerged and how it has evolved through time are two of the most fundamental and challenging questions in Earth science1,2,3,4. Metamorphic rocks—...
