GEOLOGY

Detailed explanation-1: -Mid-Ocean Ridges Seafloor spreading occurs along mid-ocean ridges-large mountain ranges rising from the ocean floor. The Mid-Atlantic Ridge, for instance, separates the North American plate from the Eurasian plate, and the South American plate from the African plate.

Detailed explanation-2: -A mountain range or hill range is a series of mountains or hills arranged in a line and connected by high ground. A mountain system or mountain belt is a group of mountain ranges with similarity in form, structure, and alignment that have arisen from the same cause, usually an orogeny.

Detailed explanation-3: -Seafloor spreading or Seafloor spread is a process that occurs at mid-ocean ridges, where new oceanic crust is formed through volcanic activity and then gradually moves away from the ridge.

Detailed explanation-4: -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-5: -plate tectonics: Seafloor spreading. The seafloor spreading hypothesis was proposed by the American geophysicist Harry H. Hess in 1960.
