a cliff
a large ocean inlet, or a narrow ocean channel between two bodies of land
This could be a fjord however the exact definition of such is rather complex and there are only four locations in the world where true fjords are found: Norway, Greenland, British Columbia and New Zealand. Other possibilities could include: an inudated river, a narrow bay, a long wide ocean inlet.
A fjord is a long, narrow inlet with steep cliffs created by glacial erosion, typically found along a coast. A river is a natural flowing watercourse that usually flows towards an ocean, sea, or another river. Rivers are typically formed by precipitation runoff or melting snow and ice.
Fjord.
The Red Sea is the inlet located between Africa and Asia.
A fjord is a narrow inlet of the sea with steep cliffs created by glaciers, while a canyon is a deep, narrow valley with steep sides formed by erosion. Fjords are typically filled with seawater, while canyons can be dry or have rivers flowing through them.
ocean cliffs is actually cavern falls!
In geography a sound or seaway is a large sea or ocean inlet larger than a bay, deeper than a bight, wider than a fjord, or it may identify a narrow sea or ocean channel between two bodies of land (see also strait).
The Atlantic Ocean.
Cliffs that are eroded by upward drafts of wind and ocean waves
An fjord is mostly made up of sea water, which flows in from the ocean through a long, narrow inlet or bay. Fjords are characterized by steep cliffs or mountainsides on either side, created by glacial erosion during the last ice age. Sediments and rocks eroded by the glacier may also be present in the fjord.
