Answer:
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. ... The lithosphere is far less ductile than the asthenosphere.
Biosphere, relatively thin life-supporting stratum of Earth's surface, extending from a few kilometres into the atmosphere to the deep-sea vents of the ocean. The biosphere is a global ecosystem composed of living organisms (biota) and the abiotic (nonliving) factors from which they derive energy and nutrients.
hot fluid or semi-fluid material below or within the earth's crust from which lava and other igneous rock is formed on cooling is called magma.
