Geographically speaking, continents are bigger than islands.

Geologically speaking, they are different in their rock density. Continents are made up of low-density rock, so they float high on Earth's molten mantle like big rafts. Ocean crust is denser, so it floats low on the mantle. Most islands are really extensions of the ocean floor - undersea volcanoes pump out dense lava that cools into ocean floor crust and sometimes piles up above sea level.

An example often quoted is that of Australia (a continent) and Greenland (an island). Geographically, Australia is a continent, not an island. As a landform, it could be considered an island as it is entirely surrounded by water and not joined onto any other land mass. For this reason, it is often referred to as an island continent. Australia is too big to be formallyclassified as an island. The world's largest island is actually Greenland.

Another reason why Australia is also considered a continent is because it sits on its own tectonic plate. This is different from Greenland, which uses the same land mass as North America. That is why the geological appearances are much different in Australia than anywhere else. A place like Greenland shares the same geologic attributes as North America.

The difference between a continent and a island is that continents sit on their own continental lithosphere and islands do not. Greenland is the largest island and Australia is the smallest continent.

Australia is not, theoretically, an island. It is a continent. It is too large to be geographically classed as an island , but it is referred to as an "island continent" because it is a continent completely surrounded by water. Antarctica is also an "island continent".

Tuvalu is considered part of the continent Australia. However, it is not actually on it, as it is an island in between Australia and Hawaii.

All continents have island associated with them. However, an island is technically not part of a continent. A continent is defined as one continuous land mass and an island is not connected to the continent.

Australia is the worlds largest island that is not a continent Sorry, but Australia is classed as a continent, the largest Island that is not a continent is Greenland.

By geographic convention, a continent is a continent and NOT an island. Therefore, Greenland is the largest island in the world (as part of North America) and Australia is a continent.

The continent is a large land mass which is independent in nature , where as the contry is the continent biengs divided into unequal landmasses.
