Continental Shelf

The submerged part of a continent that extends from the shoreline out to the point where the slope drops sharply. Think of it as the submerged part of the continent.

Continental Slope

The steep slope that marks the transition from the continental shelf to the deep-ocean floor. Imagine it as the 'cliff' that descends from a shelf to a deeper abyss.

Abyssal Plain

The flat, vast expanse of the ocean floor that lies beyond the continental slope. It's like a vast, flat plain underwater.

Mid-Ocean Ridge

Undersea mountain ranges formed by volcanic activity along areas where tectonic plates separate. Imagine it as a 'crack' in the ocean floor where magma rises and creates mountains.
