Geography question

I need to know what a landmass that is rising out of the ocean called. I used to know this but forgot. It is either in geography/oceanography. Sometimes the landmass is huge.

An island?

Continent? Archipelago?

A huge landmass surrounded by water is a continent.
A smaller landmass surrounded by water is an island.
A smallish island composed of accreted coral might be an atoll (generally surrounding with an open center).

The act of creating a mountain is known as orogenesis and some mountains begin below the surface of the water, then push up to become islands.

Volcano?

All of your answers are good, but there is a specific word for the rising landmass in progress. It might be an old word and no longer used but I seriously doubt that. I will keep looking though. Thanks.

High Mass is said on a mountaintop.

Low Mass is said in a mine.

Land Mass is said in places like Iowa.

Doesn’t matter if the land came out of the water, or even the closet.

orogeny?

I think Orogeny is correct. See this link: http://en.wikipedia.org/wiki/Orogeny

Upthrust?

I am still looking around. I found some interesting glossary sites but still haven’t found that term. You all have some interesting words but still not the one I am looking for. :smack:

Technically, High Mass is sung.

I hope you were not thinking of cordillera.

You might look at this page to see if anything rings a bell.
