WebDec 12, 2024 · The energy source for plate tectonics is Earth’s internal heat while the forces moving the plates are the “ridge push” and “slab pull” gravity forces. It was once thought that mantle convection could drive plate motions. Early textbooks showed mantle convection cells, like in a beaker of hot liquid on a Bunsen burner, pushing plates ...

WebMay 27, 2024 · There are four types of boundaries between tectonic plates that are defined by the movement of the plates: divergent and convergent boundaries, transform fault boundaries, and plate boundary zones. Microplates are smaller fragments of tectonic plates that appear in plate boundary zones. The crust of our planet is constantly evolving and … WebDivergent boundaries in the middle of the ocean contribute to seafloor spreading. As plates made of oceanic crust pull apart , a crack in the ocean floor appears. Magma then oozes up from the mantle to fill in the space between the plates , forming a raised ridge called a mid- ocean ridge. What forms when two oceanic plates move apart?
