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 intriguing case in point. The islands sitting on this chunk of continental crust constitute a sovereign state, […] The post The Biological Significance of Micro-Continents: The Fascinating Caecilians of Seychelles (and Other Parts of the World)     appeared first on GeoCurrents.

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 architecture of continents: North America is on the North American plate; South America […] The post Are Continents Rooted in Plate Tectonics? appeared first on GeoCurrents.
