Key Concepts

Plate Tectonics

This concept explains that the Earth's lithosphere is divided into tectonic plates that move relative to one another. These movements drive geological processes such as earthquakes, volcanic activity, and the creation of mountain ranges, including undersea mountain systems like the mid-ocean ridges.

Seafloor Spreading

Seafloor spreading is a process that occurs at divergent plate boundaries, where tectonic plates move apart, allowing magma to rise and solidify to form new oceanic crust. This process is fundamental to understanding how features such as the Mid-Atlantic Ridge are continuously formed and evolve over time.

Mid-Ocean Ridges

Mid-ocean ridges are extensive underwater mountain ranges formed by the upwelling of magma at divergent boundaries. They are critical components in the theory of plate tectonics and serve as sites where new oceanic crust is generated, contributing to the dynamic nature of the Earth's surface.
