Earth, home of human beings, is 70% water and 30% land which has nurtured splendid civilizations and flourishing lives. The cover story of this issue reflects the evolution of Earth by merging an unknown planet in a unified scene with different landscapes throughout the history such as glacier, desert, ocean, mountain, river and magma. The contrast between the past to reality can best illustrate our respect to our motherland. It is not only the subjects of geoscience studies, but also the common goal of all multidisciplinary research and the shared duties of mankind to understand, care and protect our planet to build a better future. |

Graphical abstract
The hadal zone, mostly comprising of deep trenches and constituting of the deepest part of the world¡¯s oceans, represents the least explored habitat but one of the last frontiers on our planet. The present scientific understanding of the hadal environment is still relatively rudimentary, particularly in comparison with that of shallower marine environments. In the last 30 years, continuous efforts have been launched in deepening our knowledge regarding the ecology of the hadal trench. However, the geological and environmental processes that potentially affect the sedimentary, geochemical and biological processes in hadal trenches have received less attention.
