Question

The island continent is …………………………….
a. Asia
b. America
c. Africa
d. Australia

Answer 1

Hint:
 Island or isle is part of the subcontinental landmass which is surrounded by water. Many small islands such as land atolls that appear can be referred to as islets, beaches, beaches, or keys. Islands in rivers or lake islands can be called eyot or ait, and small islands by the coast can be called a holm.

Complete solution:
Australia is one of seven continents, it is located in the South Pacific as an island. Australia is known as an island continent because it is the only continent that is also a country and is surrounded by water on all four sides. Geological forces such as tectonic uplifts of mountains or collisions between tectonic plates occurred primarily in early Australian history when it was still part of Gondwana. Australia is in the middle of plate tectonics and therefore there is currently no active volcanic activity.
Australia is not an island by definition and is therefore not considered an island in any book. An island is defined as the land surrounded by water on all sides and must not be continental. Because Australia is a continent it cannot be an island. It is sometimes referred to as an island continent because it is an island, except for islands by definition.

Hence, the correct answer is option D.

Note:
 Greenland is an island in the North American continent. Greenland sits on the North American tectonic plate. It is not geologically separated from Canada, the United States, and Mexico. Continents are sorted as their own tectonic plates with unique flora and fauna and unique cultures.
