WebYes, the Atlantic ocean is getting bigger and the pacific ocean is getting smaller due to the continental drift. This is caused by the natural moments of the plates as they glide on the semi-liquid mantle. This mantle often has currents caused by the subducting fluid and this force pushed the plates in many directions. Comment. WebFeb 19, 2024 · Plate Tectonics. Plate tectonics refers to the process of plate formation, movement, and destruction. It finds its foundations in two theories, continental drift and sea-floor spreading. Continental drift describes the movements of continents over the Earth's surface. Sea-floor spreading refers to the creation new oceanic plate material and ...
WebExplain what Seafloor spreading is and what is caused by it Theory that the middle of the ocean is spreading apart, forming new oceanic crust. Convection currents inside the mantle cause magma to push up through the crust creating oceanic ridges that split and move apart causing the sea floor to shift WebMantle convection is the main way heat from Earth’s interior is transported to its surface, and this heat escapes principally through mid-ocean ridges. In fact, the connected mid …
