SOLAR SYSTEM

Detailed explanation-1: -Mid-ocean ridges occur along divergent plate boundaries, where new ocean floor is created as the Earth’s tectonic plates spread apart. As the plates separate, molten rock rises to the seafloor, producing enormous volcanic eruptions of basalt.

Detailed explanation-2: -The seafloor spreading definition is the geologic process that occurs at the boundary between 2 plates where molten material within the earth pushes its way up, causing the plates to move away from each other. At these divergent boundaries molten material cools and hardens, creating new oceanic crust or seafloor.

Detailed explanation-3: -Seafloor spreading is the continuous process of forming new igneous rock at midocean ridges by injection of magma that forms new seafloor. The process is continuous because forces cause opposite sides of the midocean ridge to constantly move apart, making new room for the process to repeat.

Detailed explanation-4: -Seafloor spreading is the geologic process that results when tectonic plates split apart and move away from each other. Seafloor spreading takes place along mid-ocean ridges, which are similar to mountain ranges that extend upward from the seafloor and separate tectonic plates.

Detailed explanation-5: -Magmatic and tectonic processes at mid-ocean ridges form oceanic crust and accommodate relative plate motions. Oceanic lithosphere forms and becomes denser as the plate moves away from the mid-ocean ridge and cools.

Detailed explanation-6: -Oceanic crust is constantly formed at mid-ocean ridges, where tectonic plates are tearing apart from each other. As magma that wells up from these rifts in Earth’s surface cools, it becomes young oceanic crust.
