  1. Hi denisa123,

    This subject is still under debate. It is thought that the primitive Earth was so hot that there was not plate tectonics. Instead, there was a convection system more similar to the Lava Lamps with big drips going down and up. But when the crust got cold created a lid for the scape of the heat, and the Earth “invented” tectonics as an efficient way to disipate the inner heat.
