The geosphere is considered that portion of the Earth system that includes the Earth's interior, rocks and minerals, landforms and the processes that shape the Earth's surface. The geosphere may be taken as the collective name for the
hydrosphere (The hydrosphere is the liquid water component of the Earth. It includes the oceans, seas, lakes, ponds, rivers, and streams. The hydrosphere covers about 70% of the earth surface)
cryosphere (The cryosphere is the frozen water part of the Earth system. The Beaufort Sea, north of Alaska. One part of the cryosphere is ice that is found in water),
atmosphere( is a layer or a set of layers of gases surrounding a planet or other material body)
lithosphere is the substantial, 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 below. The lithosphere is further subdivided into tectonic plates. The lithosphere is the most rigid of Earth’s layers.
Prokaryotic cells lack a defined nucleus, but have a region in the cell, termed the nucleoid, in which a single chromosomal, circular, double-stranded DNA molecule is located.
