  1. Guyot • A seamount with a flat top due to erosion by waves, winds, and atmospheric processes. • Guyot tops are always below the ocean surface. • Also called a table mount. • Commonly found in the Pacific Ocean.

  2. Headland • A cape or other landform jutting into the ocean. • usually high above water and prominent when viewed from the sea. • It gets its name from the practice of sailors using such features to take their bearings or “headings”.

  3. Island A landmass smaller than a continent and surrounded by water.

  4. Island Chain • A group of islands formed by the same geological process • Also called an archipelago http://www.stanford.edu/group/Vitousek/flashchain.html

  5. Isthmus A narrow strip of land connecting two larger landmasses.

  6. Lagoon A shallow body of relatively quiet water almost completely cut off from the open ocean by coral reefs, barrier islands or barrier beaches.

  7. Ocean Basin • may be anywhere on Earth that is covered by saltwater, but geologically ocean basins are large basins that are below sea level. • A large depression in the earth’s crust that holds the water of an ocean.

  8. Ocean Ridge • A long continuous mountain range on the seafloor. • often of volcanic origin at a point of or line of separation in the earth’s crust.

  9. Ocean Trench • A deep cut or trench in the seafloor • deepest part of the ocean floor • Usually close to where continental shelves and seafloors meet.

  10. Peninsula • A piece of land almost completely surrounded by water. • usually connected to a larger land body by a narrow land strip called an isthmus

  11. Point • The narrow tip-end of a cape, headland, peninsula or other land feature jutting into a body of water.

  12. Reef • A shallow rock or coral formation often exposed at low tide. • fringing reef: forms along the shore • barrier reef: an offshore coral ridge

  13. Seamount • A mountain rising from the ocean seafloor that does not reach to the water's surface and thus is not an island. • An isolated undersea hill or mountain. • It is usually in the form of a cone.

  14. Shoal An area of the ocean such as a sandbar that is too shallow to navigate

  15. Sound • A wide waterway connecting two larger bodies of water. • It may be a body of water between the mainland and an offshore island.

  16. Straight A long, narrow water passage connecting two larger bodies of water.

  17. Submarine Canyon • Deep canyon cut into the continental shelf and slope • Often at the mouth (extensions) of a large river.
