The outer part of the lithosphere, specifically the part which is also part of the biosphere, from the surface of the Earth to the greatest subterranean depths at which organic life can exist. [4] biomes Large ecosystems characterized by a common climate, common vegetation, and common animal life. biosphere
Also called Indianite. A mineral from the lime-rich end of the plagioclase group of minerals. Anorthites are usually silicates of calcium and aluminium occurring in some basic igneous rocks, typically those produced by the contact metamorphism of impure calcareous sediments. anticline An arched fold in which the layers usually dip away from the fold axis. Contrast syncline. aphanic Having the ...

The anthroposphere is the youngest of all the Earth's spheres, yet has made an enormous impact on the Earth and its systems in a very short time. [ 5 ] Some consider the term anthroposphere to be synonymous with the noosphere , though the noosphere is often used to refer specifically to the sphere of rational human thought, or ‘the ...
Umbra, penumbra and antumbra of Earth and images that could be seen at some points in these areas (Note: the relative size and distance of the bodies shown are not to scale.)“… The Earth’s shadow has two distinct parts,… the UMBRA is the part of the shadow where all direct sunlight is blocked by the Earth; the PENUMBRA of the shadow is ...
Generally speaking, only a few regions of the dry-land part of the Earth are so remote or have such a harsh climate that no one uses those areas for even part of the year. These places are tiny islands, the driest part of large deserts, very high mountains, and ice caps.
The composition of the ice will vary. For example, Earth's polar caps are mainly water ice, whereas Mars's polar ice caps are a mixture of solid carbon dioxide and water ice. Polar ice caps form because high-latitude regions receive less energy in the form of solar radiation from the Sun than equatorial regions, resulting in lower surface ...
An example is how the soil acts as a part of the biosphere, [2] while also acting as a source of flux exchange. In Aristotelian physics, the term was applied to four spherical natural places, concentrically nested around the center of the Earth, as described in the lectures Physica and Meteorologica.
