Answer 3

Some sorts of rocks are sedimentary, i.e., they were created by building up sands in the sea. Later, they were pushed up and turned around etc. Often, the (formerly horizontal) layers of sand can be clearly seen and give an indication what was horizontal; and that actually there was a sea somewhen in or near this area.
