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.
A continent is basically a massive island.

An island continent is an entire continent that is completely surrounded by water. Australia is an island continent.
Technically, a continent is an island. Nonetheless, Australia is a continent.
A continent is much larger than an island.
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.
Vietnam is part of the Eurasian Continent; Australia is a separate continent (or a very large island).
A continent is basically a massive island.
The European nations of Spain and Ireland are both located along the Atlantic coast of the continent. The time difference between the two countries is 1 hour.

Yes. An isthmus can exist between two large landforms or between an island and a larger landform or continent. It is any narrow connecting neck of land. A tombolo is a sandbar that connects the mainland to an island, forming a permanent or temporary isthmus, and the island can be known as a "tied island". Tombolos form from sand or sediment pushed along a shoreline.
