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: -Plates come in a wide variety of sizes, ranging from micro-platelettes to chunks the size of North America. They are primarily composed of two fundamentally different types of rock: basalt or granite. Both basalt and granite are igneous rocks which have crystallized from magma: the molten (liquid) phase of solid rock.
Detailed explanation-3: -The asthenosphere exists as a soft layer of solid but malleable rock that can cause the tectonic plates to move and shift.
Detailed explanation-4: -In plate tectonics, Earth’s outermost layer, or lithosphere-made up of the crust and upper mantle-is broken into large rocky plates. These plates lie on top of a partially molten layer of rock called the asthenosphere.
Detailed explanation-5: -African Plate. Antarctic Plate. Eurasian Plate. Australian Plate. North American Plate. Pacific Plate. South American Plate. 14-Jan-2022
