That is patently false. Here's the definition:

con·ti·nent1 /ˈkänt(ə)nənt/ noun noun: continent; plural noun: continents

any of the world's main continuous expanses of land (Africa, Antarctica, Asia, Australia, Europe, North America, South America).

Here are some other facts about continents:

Geologically -Continents are made up of lower-density rocks than the seafloor or mantle.

Tectonic plates -Continents correlate with the positions of tectonic plates. Geologists theorize that continents move due to plate tectonics.

Mountain formation -Mountains form on continents when tectonic plates crash together, creating wrinkles in the crust.

Name -The word "continent" comes from the Latin terra continēns, which means "land held together" or "connected land".

The definition has nothing to do with how much water is surrounding it. Try again homie.
