Concept in Definition ABC

It is known with the term of island to that portion of land, smaller than the size of a continent, which is totally and from all angles, surrounded by Water.

Any surface of any island, taken at the same height of sea level, is characterized by observing a weather similar, unlike what happens with the continents, presenting the climatic situation, as we all know from our own experience or for having studied it, quite irregularly in the various regions of the continents, for example, the climate of a continent in the South will be very different and opposed to the North.

Islands can be found in seas, lakes, rivers, and oceans, that is, in all those places where water rules by the way and with respect to its extension, although as we mentioned and as it happens in most Of the cases, the islands can boast from a few square meters to more than two million square kilometers, such is the case of Greenland

The origin of the islands can be found in various factors how to be erosion and sedimentation

, this being the case of those that are located in seas and oceans, for example, evolve and increase in size as a consequence of the deposit of sediment and the accumulation of material organic and volcanic or after an erosive process, a portion of land separates from a continent giving rise and origin to the islands. Likewise, the rise in sea level causes the birth of the islands, in this case, the lowland is submerged, leaving the highest part of the islands separated.

Then we can find the following types of islands, the continental ones, which are those that are connected to the continent along the continental shelf, as in the case of Greenland that we mentioned before and then we have the volcanic ones that have their reason for being in the activity volcanoes, coral, which are found in tropical or subtropical seas, sedimentary, which are formed in the river mouths by the accumulation of sand, for example, and fluvial, which are formed from bars that are find in the channel central of a River.
