One of seven main landmass on Earth
a very very large piece of land that is surrounded by water
Europe is a continent so it does meet the definition of a continent.
Islands are by definition, not in or on a continent.
Islands are by definition, not in or on a continent.
By definition, no continent can be landlocked.
A continent is a large, continuous landmass on Earth, such as North America or Africa.
By definition the Galapagos Islands are not on a continent.
The Swiss Alps are, by definition, in Switzerland, which is on the continent of Europe.
What is smaller than a continent and is completely surrounded by water
Australia is both a country and a continent, but it does not fit the geographical definition of an island. Being surrounded by water, it is classed as an island continent, but not an island.
Both. Australia is large enough to be a continent but is an island by definition, as it is surrounded by water on all sides. It is known as an island continent, as is Antarctica.
A continent is one of Earth's major landmasses, typically identified by its distinct geographical boundaries and separated from other continents by oceans. There are seven continents: Africa, Antarctica, Asia, Australia, Europe, North America, and South America.
You have to be Africa, Europe, Asia, North America, South America, Antarctica or Australia. There's really no specific geographical definition that says "Australia is a continent, but Greenland isn't" or "Europe is a continent, but Alaska isn't."
