What is sea-floor spreading?

Back

Sea-floor spreading is the process by which new oceanic crust is created at mid-ocean ridges as tectonic plates move apart.

5.

FLASHCARD QUESTION

Front

What is a divergent boundary?

Back

A divergent boundary is a tectonic plate boundary where two plates move away from each other, leading to the formation of new crust.

6.

FLASHCARD QUESTION

Front

What is the Pacific mid-ocean ridge?

Back

The Pacific mid-ocean ridge is a continuous mountain range located in the Pacific Ocean, where sea-floor spreading occurs.
