As noted in the previous post, most maps of continents found in online images searches divide several countries, particularly Russia and Turkey, along conventional continental lines yet avoid dividing Indonesia in the same manner. Evidently, in the popular cartographic...

The division of the terrestrial world into seven continents is seemingly the simplest topic in geography, yet it is actually one of the most complex – which is precisely why I find it so fascinating. Unfortunately, the educational establishment grasps only its superficial...

The two previous GeoCurrents posts examined the biological significance of continents by looking at the distribution of animals. It is time now to turn out attention to plants. One of the most influential divisions of the world into “floristic kingdoms” is that of botanist Ronald...

An important 2013 article in published in Science, “An Update of Wallace’s Zoogeographic Regions of the World,” redivides the world’s faunal regions. The study is based on a sophisticated statistical and phylogenetic analysis of 21,037 species of amphibians, non-pelagic birds and...

If the division of the terrestrial world into continents is partially but misleadingly rooted in geology, as recent GeoCurrents posts have argued, we must also ask whether it reflects the distribution of animal and plant life. Are continents, in other words, entities of...

On the surface, there is little to distinguish small islands on continental fragments from oceanic islands that have no continental connections. Careful observation, however, can reveal some interesting differences. The Seychelles microcontinent in the Indian Ocean is an...

As the previous GeoCurrents post argued, the division of the terrestrial world into a handful of continents derives in part from the division of the Earth’s crust into tectonic plates. But there is another geological factor equally pertinent to the concept of “continent.” It...

Many maps, in my view, are also work of art, regardless of their creators’ intentions. Some maps, however, are explicitly made as art, and as such are not designed to convey spatial information beyond that found in the mere geographical shapes that they contain. Increasingly, it...

Tectonic plates are the basic building blocks of the Earth’s lithosphere, its outermost rocky layer. As these large segments of crust slowly move, landmasses and sea expanses are gradually rearranged. The current configuration of tectonic plates shows a tight connection with the...
