GEOLOGY

Detailed explanation-1: -Tectonic plates are gigantic pieces of the Earth’s crust and uppermost mantle. They are made up of oceanic crust and continental crust. Earthquakes occur around mid-ocean ridges and the large faults which mark the edges of the plates.

Detailed explanation-2: -Huge pieces of lithosphere that slowly move on the asthenosphere and consist of the crust and the rigid, uppermost part of the mantle. A tectonic plate division of the lithosphere that includes the continental crust of Greenland, North America, Siberia, and the surrounding oceanic crust.

Detailed explanation-3: -The perpetual “slip ‘n’ slide” motion of the lithosphere on the asthenosphere caused it to fragment into several large sections called tectonic plates.

Detailed explanation-4: -Plate Tectonics The most well-known feature associated with Earth’s lithosphere is tectonic activity. Tectonic activity describes the interaction of the huge slabs of lithosphere called tectonic plates.

Detailed explanation-5: -The upper mantle extends from the crust to a depth of about 410 kilometers (255 miles). The upper mantle is mostly solid, but its more malleable regions contribute to tectonic activity. Two parts of the upper mantle are often recognized as distinct regions in Earth’s interior: the lithosphere and the asthenosphere.
