cooled
The flow of mantle effects convection currents in the mantle. This process happens as hot material within the mantle begins to rise. As it rises, it begins to cool and then sinks. This process repeats as a cycle of convection currents.
convection currents discovery date
tectonic plates move by convection currents. Convection currents are currents that start by hot air rising and eventually turning cooler then lowers. This continues in a constant pattern like a week.
there are noneactually this answer is wrong the REAL ANSWER IS: ice skating, ice hockey,and hot air balloon competitions
Convection currents can vary in thickness, typically ranging from a few centimeters to kilometers depending on the scale of the system in which they occur. In the Earth's mantle, for example, convection currents can be tens to hundreds of kilometers thick.
yes
Convection currents
the earth's convection currents cause continental drift.
Convection currents.
Yes. Convection currents move hot materials to other places.

convection currents are when hot rock from deep inside the the earth rises but cooler rock near the surface sinks

They are the solid crustal rock floating on the top of a mantle convection cell. They formed the same way slag forms on the tops of convection cells in the molten metal in a smelter furnace. Sections of the mantle also float on the tops of convection cells in the molten metal of the liquid core. If you want to watch the tops of some convection cells form and move, get a cup of some hot drink (e.g. coffee or tea) and let it sit undisturbed for a minute or so to let all currents but convection currents stop. When you look at the surface of the hot drink it will be covered in very tiny polygons. These polygons are the tops of convection cells in the drink, don't they look something like a miniature map of crustal plates? Watch as they expand, contract, and move about.
