I believe the correct answer is A. Irtysh
Answer:
The lithosphere-asthenosphere boundary
Explanation:
because is conventionally taken at the 1300 °C isotherm. Below this temperature (closer to the surface) the mantle behaves rigidly; above this temperature (deeper below the surface) it acts in a ductile fashion.
Global warming impacts terrestrial biomes since it brings about <span>decreased precipitation and longer winter seasons. Global warming refers to the increase in temperature of the Earth's atmosphere. This is brought about by release of greenhouse gases (e.g. carbon dioxide, methane) in the air which trap heat in the Earth's atmosphere. As a result, there is increased variability of weather and climate patterns. </span>
By population concentration and density
Variations in air pressure from place to place are the principal cause of wind. It is air in motion.<span> It is produced by the uneven heating of the earth’s surface by the sun.</span><span> Hope this answers the question. Have a nice day. Feel free to ask more questions.</span>
