WebThe mesosphere is the coldest layer in the atmosphere, where the temperature goes down as low as -120 degrees Celsius. The thickest layer of the atmosphere is the thermosphere. Air density is too low in the thermosphere. The lower thermosphere is called the ionosphere, and this ionosphere features electrically charged particles known as ions ... WebFeb 26, 2024 · Based on Composition: According to its composition, broadly it is divided into two layers-homosphere; heterosphere; Homosphere. The homosphere is the lower segment of the two-part division of atmosphere and further consists of three regions namely troposphere, stratosphere and mesosphere. The Troposphere is the earth’s weather layer.

The mesosphere of Venus can be divided into two layers: the lower one between 62 and 73 km and the upper one between 73 and 95 km. In the first layer the temperature is nearly constant at 230 K (−43 °C). This layer coincides with the upper cloud deck. WebThe mesosphere refers to the mantle in the region under the lithosphere, and the asthenosphere, but above the outer core. The upper boundary is defined as the sharp increase in seismic wave velocities and density at a depth of 660 km. As depth increases, pressure builds and forces atoms into a denser, more rigid structure; thus the difference … hamit tuncer
