Where is the (ancient) ocean floor?

Abstract

Focus:

To understand that that the ocean floor is dynamic and changes through time. Sometimes it’s far away, and sometimes much closer than we think. But where is the ocean floor?

Learning objectives:

Key words:

Sedimentation, sedimentary rocks, tectonics, Earth history.
