True
A continuous flow in the mantle caused by differences in density
Density.
conduction is transfer of energy due to direct contact, convection is due to density differences
ocean currents are caused by difference in temperatures and salinity lol :) :P hehe
gravity on masses of seawater that are denser than surrrounding water causeing the denser water to sink .density currents slowly circulate deep ocean water.cool current from the western coast originate far from the equator , warm currents along eastern coast begin near the equator ,differences in temperature an salinity between water masses in the ocean setup circulate called density currents
because of differences in pressure and density in a fluid
convection currents
Convection occurs whenever a less dense liquid is beneath a denser liquid.
A continuous flow in the mantle caused by differences in density
heat energy
It just happens because of the differenciation in the air density which allows the so called convection currents to occur/form. Complex I know but is the closest conclusion.
the differences in density cause the fluids to move in currents, which mixes them all together so that they may lose heat to the other fluids, thus transferring energy through convection
Temperature differences in the mantle drive convection currents because warm material is less dense and rises, while cooler material is more dense and sinks. This movement creates a circular flow as the cooler material sinks and gets heated, while the warmer material rises and cools down. The density variations caused by the temperature differences are a key driver of convection in the mantle.
Differences in a materials __________ is what drives convection
It's the change (decrease) in density with heating that produces the currents that we refer to as convection currents.
The difference in temperature and density is the cause of convection currents in the earths mantle. Convection currents are the flow that transfers heat within a fluid.
