convection currents are set into motion by heat.without heat the convection currents would stop when all the material reaches the same temperature.
Birds use convection by using convection currents the heat will rise as a draft and then birds can ride the draft to reach higher altitudes.
It'll stop flowing when all of the material has reached th same temperature.
Heating from the Earth's core drives convection in the upper mantle. This convection is extremely slow; the speed with which material in the Earth's crust spreads from the mid-ocean ridges is of the order of several cm per year. Nevertheless, it is evident that the same forces which drive convection in the atmosphere and in the ocean are present in the "solid" earth as well. Mantle convection is the slow creeping motion of Earth's solid silicate mantle caused by convection currents carrying heat from the interior of the Earth to the surface.

A. Pressure systems determine where the wind blows, and while geography can affect those pressure systems it will not always affect it in the same way.
There are convection currents in the mantle because if they werent everything would be the same temprature

They both are the same because they are currents that move like waves
Yes. Convection is a type of energy and a convection current is, well, the phrase for its currents. So yeah, convection and convection current are the same.

Convection currents can form when there a temperature differential within the same body of a liquid or gas and the higher temperature obtains at a lower vertical position than the cooler liquid. If the relative vertical temperatures are reversed, convection currents may be prevented by what is known as a thermocline, i.e., a static layer of liquid which effectively prevents mixing of the different temperatures necessary to produce convection.

Yes, it is believed that the movements of Plate Tectonics is generated by the convection currents in the mantle. The continents are made up of rocks somewhat lighter than the dense dark-coloured volcanic rocks of the interior. They therefore float on the denser rocks. The same convection currents, or the net effect of them, is believed to generate the electric currents that produce the Earth's magnetic field.
They occur in the Mantle.Prettyorc345Your welcome! I had the same problem on my science homework :)

All earthquakes have the same cause, which is the movement of the Earth's crustal plates resulting from convection currents in the magma upon which they float.
Cool things always sink (because they are more dense) and hot things always rise (because they are less dense) in convection. It does not matter if it is rock, air, water, metal, wax, oil, etc., convection always works the same.
