Definitions:

Seafloor Spreading

The process by which two oceanic plates move apart and new magmatic material is added between the plates.

Continental Rifting

The pulling apart of a continent, forming a low, fault-bounded trough (continental rift); may lead to a divergent plate boundary that leads to seafloor spreading and splitting apart a continent.

Continental Shelves

Submerged landforms at the edges of continents, extending from the coastline to a sharp drop-off into the deeper ocean floor.

Shallow Seawater

Areas of the ocean that are not deep, often found near coastlines, characterized by relatively low depths.
