Quantitative indicators of the influence of the shape of the Earth (ellipsoidal with modern polar compression or spherical) on the characteristics of its irradiation calculated without taking into account the changes in the solar activity have been obtained. The differences between specific energies as ...
Characteristics of the Earth's Terrestrial Biomes Many places on Earth share similar climatic conditions despite being found in geographically different areas. As a result of natural selection, comparable ecosystems have developed in these separated areas. Scientists call these major ecosystem types biomes...

This destruction results because surface waves are channeled through the thin outer region of Earth, and their energy is less rapidly scattered into the large volumes of rock traversed by body waves. 3.In paragraph 3, the author presents the characteristics of S-waves by A. comparing and cont...
Since Earth is the only habitable planet known to humankind, the orbital and physical characteristics of Earth are used to define a habitable planet. In other words, habitability is the characteristic of an environment which has similar properties as those of Earth, and the capability of developing...
