Detailed explanation-1: -The geosphere includes all the rocks that make up Earth, from the partially melted rock under the crust, to ancient, towering mountains, to grains of sand on a beach. Both the geosphere and hydrosphere provide the habitat for the biosphere, a global ecosystem that encompasses all the living things on Earth.

Detailed explanation-2: -The Lithosphere–contains all of the cold, hard solid land of the planet’s crust (surface), the semi-solid land underneath the crust, and the liquid land near the center of the planet. The surface of the lithosphere is very uneven.

Detailed explanation-3: -The geosphere includes the rocks and minerals on Earth – from the molten rock and heavy metals in the deep interior of the planet to the sand on beaches and peaks of mountains. The geosphere also includes the abiotic (non-living) parts of soils and the skeletons of animals that may become fossilized over geologic time.

Detailed explanation-4: -The four spheres are the geosphere (all the rock on Earth), hydrosphere (all the water on Earth), atmosphere (all the gases surrounding Earth), and biosphere (all the living things on Earth).

Detailed explanation-5: -The Earth’s geosphere is divided into three chemical sections: The crust, composed almost entirely of light elements, like silicon. The mantle, which is 68% of the Earth’s mass. The core, the innermost layer; it is composed of very dense elements, such as nickel and iron.
