The biosphere (from Ancient Greek βίος (bíos) 'life' and σφαῖρα (sphaîra) 'sphere'), also called the ecosphere (from Ancient Greek οἶκος (oîkos) 'settlement, house' and σφαῖρα (sphaîra) 'sphere'), is the worldwide sum of all ecosystems. It can also be termed the zone of life on Earth.
All the water bodies on the Earth's surface comprise the hydrosphere. The blanket of different gases above the Earth's surface is called atmosphere. The zone where the lithosphere, hydrosphere and atmosphere interact together to make life possible on Earth is called biosphere.
Sep 16, 2024 · This generation of life in the thin outer layer of the geosphere established what is called the biosphere, the “zone of life,” an energy-diverting skin that uses the matter of Earth to make living substance.
- The biosphere is the thin life-supporting stratum of Earth’s surface, extending from a few kilometres into the atmosphere to the deep-sea vents of...
- The biosphere supports all life on Earth, 3 to 30 million species of plants, animals, fungi, single-celled prokaryotes such as bacteria, and single...
- The two components of the biosphere are called the abiotic and the biotic. The abiotic, or nonliving, portion of each ecosystem includes the flow o...
- The major cycles that occur in the biosphere are the carbon cycle, nitrogen cycle, sulfur cycle, phosphorus cycle, and hydrological (water) cycle.
Jun 13, 2023 · Earth dwells in the “habitable zone,” the orbital distance from a star that allows liquid water to pool on a planet’s surface under a suitable atmosphere. Life on Earth inhabits a shockingly diverse range of conditions, from deep cold to caustic, boiling pools, but all appear to require liquid water.
Oct 19, 2023 · The biosphere is made up of the parts of Earth where life exists—all ecosystems. The biosphere extends from the deepest root systems of trees, to the dark environments of ocean trenches, to lush rain forests, high mountaintops, and transition zones like this one, where ocean and terrestrial ecosystems meet.
The biosphere is the narrow zone on the surface of the earth where land, water, and air interact to sustain life. Biotic and abiotic resources are the types of the biosphere. The Biosphere is divided into areas known as Biomes.
The habitable zone is the not-too-hot, not-too-cold region around a star where liquid water can exist on a planet’s surface. Liquid water is a key ingredient for life as we know it, so exoplanets in their stars’ habitable zones are compelling places to search for life.
