Tectonic Plate Formation

While Earth’s plates continuously create new ocean floor and continental land, but also makes it disappear. At divergent plate boundaries, the plates push together and magma rises to the surface. When this magma cools it creates new plate material. Scientists know this because the seafloor near these volcanoes is the youngest seafloor in the ocean. At convergent subduction plate boundaries the plates subduct, and one plate goes into the Earth. As this plate gets lower it slowly starts to melt and becomes magma. Scientists know that the plate is destroyed because of the Law of Conservation of Matter, which states that matter cannot be created or destroyed, only recycled. As the new plate material is created,
