Seafloor Spreading

The process by which new oceanic crust is created at mid-ocean ridges as tectonic plates diverge, leading to the gradual widening of an ocean basin.

Glaciers

Slow-moving rivers of ice formed by the accumulation and compaction of snow on mountains or near poles, which shape the land through erosion.

Sea Level

The average height of the ocean's surface between the high and low tide, used as a standard in reckoning land elevation or sea depths.
