What is biosphere ? Name the three groups of physical portion of biosphere.
Answers
Answer:
with three other spheres of the physical environment: the lithosphere, the hydrosphere, and the atmosphere. The lithosphere is the solid outer layer of the Earth's crust, including rocks, sand, and soil.
Answer:
The biosphere is the sum of all living matter on the Earth. Highly specialized organisms have adapted to the extreme boundaries of the uppermost atmosphere and lowermost ocean depths. The biosphere is interconnected with three other spheres of the physical environment: the lithosphere, the hydrosphere, and the atmosphere.
The lithosphere is the solid outer layer of the Earth's crust, including rocks, sand, and soil. The Earth's lithosphere is a dynamic area, with processes such as erosion, earthquakes, and plate tectonics
constantly altering and forming/destroying the surface. The tectonic cycle describes the formation of new crust in some areas and its destruction in others.
Plate tectonics is the geological theory that proposes the lithosphere is composed of tectonic plates that are in constant motion relative to each other. New oceanic crust forms at divergent plate boundaries, which are expressed on the Earth's surface as midocean ridges (undersea) or rift valleys (on land). The mid-Atlantic Ridge and the East African Rift are examples of these features.
