Geologists believe that covection currents are what causes continental drift. If covection currents never happened and their force didnt move the continents then we'd all live on one large super continent.
In a convection current, the particles nearest to the heat gain thermal energy, so start to vibrate more and move slightly further apart from one another, therefore becoming less dense and rising. Once these particle get further away from the heat source, they begin to cool down, so the the particles vibrate less and get closer together. This means that they become more dense and sink back down towards the heat sorce, where once again they are heated and the process starts all over again. A convection current can only happen in a liquid or a gas.
Diverging currents are currents that are deviating and usually take place to ocean currents. This will be marked by an inconsistent airflow pattern of the currents.
covection?
covection of the atom
A difference between gyres and currents is that currents are formed by the wind, but gyres are formed by currents.
No. Electric currents differ quite significantly from ocean currents.
um it is the covection moving

The major ones involve the mantle and the oceanic crust.
A convection current is how either water or air cools and heats. The thing that causes them is the heating and cooling of air or water which makes it rise or sink.
They both have covection currents and effect the weather
As the fluid warms:The currents speed upThen as the temperatures of the fluid equalise (the fluid becomes one temp) the currents slow downWhen the fluid is one temperature the currents stop
When a part of the earth's upper mantle or lower crust melts, magma forms. A volcano is essentially an opening or a vent through which this magma and the dissolved gases it contains are discharged.
Wave action, Volcanic activity and land and water erosion are needed to have salinity currents form. Hope this helped@ :)
Well, i don't know what causes them but i do know how they form.Convection currents are formed somewhere in the upper mantle below the asthenosphere and is called the mesosphere.the mantle material,(the hotter material) rises on the surface of the asthenosphere,and pushes the cooler material out of the way,sinking back into the Earth becoming more and less dense each time. Hope this helped! :)
The sun is the original source of energy for such winds and currents.
