Web9 mei 2024 · Introduction. In 1963, J. Tuzo Wilson, the Canadian geophysicist who discovered transform faults, came up with an ingenious idea that became known as the "hotspot" theory. Wilson noted that in certain locations around the world, such as Hawaii, volcanism has been active for very long periods of time. This could only happen, he … WebImagine a burning candle, and imagine moving a sheet of heavy paper slowly over the flame of the candle.You're gonna get a series of burned spots in the paper.Well, that's just like what's happening with the Hawaiian Islands, but instead of a sheet of paper, you've got a tectonic plate,and it's moving over this plume of intensely hot magma.And ...

Magma plumes and plate movement

WebThe mantle’s convective motions break the lithosphere into plates and move them around the surface of the planet. These plates may move away from, move by, or collide with each other. This process forms ocean basins, shifts continents, and pushes up mountains. Tectonic plates break apart and diverge where the mantle beneath is upwelling.
