Mid Ocean Ridge
Mid ocean ridge explained in an easy to understand way:


Imagine you're trying to bake a loaf of bread, and as it rises, the dough splits in the middle, revealing a stretch of raw dough as it expands. Similarly, a mid-ocean ridge forms when molten rock from beneath the Earth's crust pushes upward, causing the seafloor to spread apart and create a mountain range. Just as the dough surfaces and stretches apart to reveal the soft interior, the Earth's crust splits and allows lava to emerge and solidify, forming new oceanic crust at the mid-ocean ridge.

Mid Ocean Ridge: A long mountain range on the seafloor formed by lava eruptions through Earths crust. Mid-ocean ridge. A mid-ocean ridge is an undersea mountain range where new oceanic crust is created by volcanic activity.
