Physical Oceanography

6. A navigable shallow area of the ocean caused either by elevation of the seafloor or by submergence of a landmass
9. A broad, sloping deposit of sediments at the mouth of a river or at the foot of a submarine. canyon or a river canyon
10. A large depression in the earth's crust that holds the water of an ocean.
12. The land forming the shallow seafloor extending outward from the edge of a continent
14. A group of islands formed by the same geological process
16. An isolated undersea hill or mountain. It is usually in the form of a cone.
17. An area of the ocean, such as a sandbar, that is too shallow to navigate.
18. A shallow rock or coral formation often exposed at low tide.

1. A piece of land almost completely surrounded by water. It is usually connected to a larger land body by a narrow land strip called a neck or an isthmus.
2. The area of the continental shelf between the continental slope and the deep seafloor where sediments from the continent accumulate.
3. A ring-shaped coral reef surrounding a lagoon. It may have low sand islands.
4. A deep cut or trench in the seafloor, usually close to where continental shelves and seafloors meet.
5. A flat region of deep ocean basins.
7. A landmass smaller than a continent and surrounded by water.
8. A very steep or overhanging land feature.
10. A long, continuous mountain range on the seafloor. Ocean ridges are often of volcanic origin at a point or line or separation in the earth's crust.
11. A wide waterway connecting two larger bodies of water. It may be a body of water between the mainland and an offshore
13. A shallow body of quiet water almost completely cut off from the open ocean by coral reefs, barrier islands, or barrier
15. A strip of land bordering the sea.
