    In geologic terms, a plate is a large, rigid slab of solid rock. The word tectonics comes from the Greek root "to build." Putting these two words together, we get the term plate tectonics, which refers to how the Earth's surface is built of plates. The theory of plate tectonics states that the Earth's...

  • Characteristics of Mid-Oceanic Ridges
    Ocean basins are expanding laterally away from a mid-oceanic ridge. Radioactive decay in Earth’s mantle causes convection cycles, which drive plate tectonics. Hot mantle rises and undergoes decompression melt due to change in pressure. New oceanic crust is created in a characteristic sequence. Studies...
