* Divergent Plate Boundaries: These are areas where tectonic plates move apart.
* Magma Upwelling: As plates pull away, it creates space for magma from the Earth's mantle to rise to the surface.
* Volcanic Activity: This rising magma erupts, forming underwater volcanoes and volcanic islands.
* Mid-Ocean Ridge Formation: Over time, these volcanic eruptions create a continuous chain of mountains under the ocean called a mid-ocean ridge.
Key Features of Mid-Ocean Ridges:
* Central Rift Valley: A depression in the middle of the ridge where new crust is forming.
* Hydrothermal Vents: Hot springs that release chemicals and minerals from the Earth's interior.
* Pillow Lavas: Unique lava formations that solidify in water.
Examples:
* Mid-Atlantic Ridge: The most well-known mid-ocean ridge, running down the center of the Atlantic Ocean.
* East Pacific Rise: Another prominent mid-ocean ridge in the Pacific Ocean.
