It has been thought that the existence of plate tectonics has been a significant factor in the shaping of our planet and the evolution of life. Mars and Venus don’t experience such movements of crustal plates but then the differences between the worlds is evident. The exploration of exoplanets too finds many varied environments. Many of these new alien worlds seem to have significant internal heating and so lack plate movements too. Instead a new study reveals that these ‘Ignan Earths’ are more likely to have heat pipes that channel magma to she surface. The likely result is a surface temperature similar to Earth in its hottest period when liquid water started forming.
