Previous models of Earth's recent (100 million years) geomorphology have been patchy at best. For the first time a detailed continuous model of the Earth's landscape evolution is presented, with ...

Earth is fortunate in having a magnetic field: it protects the planet and its life from harmful cosmic radiation. Other planets in our solar system—such as Mars—are constantly bombarded by charged ...

During the Sturtian glacial period during the Neoproterozoic Era, Earth underwent periods of global glaciation, which have ...
