In Earth’s mantle there are two huge ‘islands’ with the size of a continent. These regions are hotter than the surrounding cold sunken tectonic plates, and that they are ancient: at least half a billion years old. These observations contradict the idea of a well-mixed and fast flowing Earth’s mantle
