Convection currents in earth's interior
WebThe slow deformation of deep rock, they theorized, would generate convection currents in Earth’s interior. The currents would be like the rising and falling currents of water boil-ing in a pan, but vastly larger and much, much slower. These geologists further proposed that such currents may be rising under ridges then known only vaguely to ... WebScientists study mantle convection, or the flow of hot rock in the Earth's deep interior, in order to better understand how this flow shapes the surface of the Earth. When a solid, liquid, or gas is heated, it expands, becomes less dense, and rises. ... These convection currents move lithospheric plates through three main hypotheses: 1 ...
