The large sections of the lithosphere are called tectonic plates. These plates are made up of the crust and upper mantle of the Earth, and they sit on top of the asthenosphere.Know More
The tectonic plates are an important part of understanding the evolution of the appearance of the Earth through the years. In general, the plates measure about 100 to 200 kilometers thick. Underneath these tectonic plates, the hot asthenosphere moves and causes the movement of the plates above.
The movement of these plates causes the land masses to slowly move. Earth looks very different in modern times than millions of years ago. Continents collide and move apart as a result of the plates. The movement of two plates against one another causes earthquakes and forms mountains.Learn more in Geology
The upper mantle forms part of the Earth's lithosphere, where earthquakes and volcanic activities frequently occur along plate boundaries. The upper mantle is separated from the crust by the Mohorivicic discontinuity, commonly referred to as "Moho," which derived its name from the Croatian scientist Andrija Mohorovicic.Full Answer >
According to About.com, plate tectonics is the scientific theory that attempts to explain the movement of the Earth's lithosphere, which has formed the landscape features seen across the globe. It provides geology with a comprehensive theory that explains how the Earth works.Full Answer >
The crust and upper mantle of the Earth form the lithosphere. The lithosphere is about 62 miles thick. The part of the lithosphere that supports the continents is thicker than the part of the lithosphere that supports the oceans.Full Answer >
The separate sections the lithosphere are broken into are called tectonic plates. The shifting of tectonic plates can cause volcanic eruptions and earthquakes.Full Answer >
