Question

eassy on lithosphere

Answer 1

The lithosphere is composed of the upper crust, 5 km thick in the oceans and 65 km thick on the continents, and the upper mantle, which makes up the remainder. The continental lithosphere is comprised of igneous rock called felsic rock. This rock is rich in the elements required to form quartz and feldspar. The oceanic lithosphere is comprised of mafic crust and ultramafic mantle. The mafic crust is made up of silicate mineral that is rich in iron and magnesium. The lithosphere is the solid, outer part of the Earth. The lithosphere includes the brittle upper portion of the mantle and the crust, the outermost layers of Earth's structure. It is bounded by the atmosphere above and the asthenosphere (another part of the upper mantle) below. Lithosphere provide us forests, grasslands for grazing land for agriculture and human settlements and also rich source of minerals. The lithosphere contains different types of rocks such as the igneous, sedimentary and metamorphic rocks, it helps to provide the necessary nutrients required to plants. The lithosphere is largely important because it is the area that the biosphere (the living things on earth) inhabit and live upon. If it weren't for the tectonic plates of the lithosphere there would be no charge on Earth.
