Convection, Conduction And Thermal Radiation

EVALUTATE THE EVIDENCE. HEAT TRANSFER IN THE EARTH. Heat hit is the reasonableness of higher temperatures to lower temperature beas. This occurs within the earth by conductivity, convection and thermal radiation. Conduction occurs in both solids and fluids when adjoining particles vibrate so that they diffuse screw up to one another by dint ofout a space, until all of the particles are the same temperature. Conduction performs a epoch-making role in the lithosphere as this is the place conductivity occurs and also as this is where the basis loses most of its internal heat. on the mid-ocean ridges where the temperature is signifi after parttly high, mainly along the most active and body of work ridges, the tectonic plates thicken as they move away from the ridges and cool. From this retell we privy see that conduction is an important process as it moves the heat from the upper mantel through the lithosphere to the kingdoms crust. Convection is another method of heat change over. This occurs when heat is transported through a large movement of heated molecules. The temperature of a liquid is relative to its density and this is when convection occurs. Cooler rocks higher in the mantle are denser than the hotter rocks below them and this is where gravity forces the colder rocks down, as they are heavier.

Convection dominates the thermal conditions in the areas where large amounts of fluids, mostly being melt down rocks, exist, and because it controls the transport of heat from the mantle and the fluid outer core. Convection can only occur in liquids, however, the mantle and Earths crust are solid, and we know thi! s due to studies showing S-waves that proceed through these areas. This then shows that the rocks move as they are at very high temperatures that are, however, below melting point, and are soft. This key out therefore shows that convection is the most important process of heat budge as it moves the heat across the largest area. Another heat stir process is thermal...If you want to get a full essay, gash it on our website: OrderCustomPaper.com
