Detailed explanation-1: -In general, the geosphere is considered to comprise the entire solid Earth and its atmosphere. The Earth’s solid body is divided into the interior and exterior core, the mantle and the crust. The thin layer at the top of the crust is called the pedosphere. A high proportion of the earth is covered by water.

Detailed explanation-2: -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-3: -The geosphere includes the innermost layer of the planet, all the way up to Earth’s surface crust on which living organisms live. This sphere explicitly contains all of the solid rock on Earth and the liquid molten rock deep beneath Earth’s crust.

Detailed explanation-4: -The lithosphere is the solid part of the Earth such as rocks and mountains. The hydrosphere is the liquid water such as the rivers, lakes, and oceans. The cryosphere is the frozen water of the earth and is further broken into four types: glaciers, snow cover, floating ice, and permafrost.

Detailed explanation-5: -The geosphere or rocky Earth formed from collisions of planetoids. During the turbulent Priscoan/Hadean era, heavy metallic elements sink down to become the inner core, lighter ones rise to be the mantle. Formation of the crust as a sort of “scum” floating on the mantle.
