Crustal plate movement occurs because the mantle flows as a result of uneven heating inside the mantle. _____ are created by very hot material deep in the mantle rising, then cooling, sinking again, and then heating again and then repeating the cycle.

Did you know?
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… WebMar 21, 2013 · Convection currents are the movement of fluid as a result of differential heating or convection.

WebMar 29, 2024 · Convection is often described as a combination of two physical processes: advection and diffusion. Advection is the transport of matter by bulk motion, such as the movement of riverbed silt by the flow of the river. Diffusion is the transport of matter by particle motion from an area of high concentration to an area of low concentration, such … WebDec 31, 2024 · Due to the fact that the earth’s axis is tilted, heat and solar radiation is unevenly distributed. Because of our unique circumstances, heat accumulates at the equator naturally, thus leaving the poles without heat. The Earth uses various processes to circulate warm air towards the poles and move cooler air towards the equator.

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. canina formation noisy le grandWebIdentify each event as the result of mechanical weathering or chemical weathering.
