On Earth, the Rayleigh number for convection within Earth's mantle is estimated to be of order 10 , which indicates vigorous convection. This value corresponds to whole mantle convection (i.e. convection extending from the Earth's surface to the border with the core). On a global scale, surface expression of this convection is the tectonic plate motions, and therefore has speeds of a few cm per year. Speeds can be faster for small-scale convection occurring in low-viscosity regi… WebOct 5, 2024 · In the convection cycle, air will rise due to the heat that is displayed by the sun.

A more … WebSep 30, 2024 · In summary, we can say that the normal convection cycle occurs when a hot fluid expands, it reduces density and rises because it is less dense than the surrounding environment. Convection currents are the result of the heat flow that makes the hotter material less dense and ascends the surface. WebSep 8, 2024 · The difference between fog and clouds (which form above the Earth's surface) is that rising air is not required to form fog. Fog develops when air having a relatively high humidity encounters a colder surface, often the Earth's surface, and cools to the dew point. Additional cooling leads to condensation and the growth of low-level clouds. cincinnati bengals maternity clothes
