It is usually defined at islands as portions of land surrounded by water, although it is true that continents would fit in this definition as well.
However, they differ from these because they appear surrounded by water everywhere and by their dimensions, since they are much smaller.
One of its common characteristics of the islands is that the climate is strongly conditioned by the proximity of the sea.
From the biological point of view, the islands differ from the continents because their isolation limits the number and variety of animal and plant species that can be found in them. Often, two islands, which are quite close to each other, have a very different flora and fauna.
The climate of the islands
Except in the interior of a few, very large, the climate of the islands is determined by sea winds and this depends on its degree of humidity, rainfall and temperature. When the island has mountains that cause the rise of humid air, rains are often produced, sometimes constant.
The climate of the islands is also usually influenced by sea currents. These provide warmer air, since cold currents move submerged and, therefore, affect them less. For this reason, similar climates can be found on islands of different latitudes.

The largest island is Australia, with an area of almost 7.6 million square kilometers. However, Australia is usually considered a continent, due to its quasi-continental characteristics.
