This volume includes six chapters in earth science research. Chapter One explores the importance of thermodynamics and systems theory in terms of understanding the evolution, ecology and sustainability of the Biosphere. Chapter Two presents new data on variations of the ?13C and ?15N values in natural plant species and in the rhizosphere soil. Based on experimental results, this chapter also tries to better understand the large and often unexplained variability of the C and N isotope ratios in the environment. Chapter Three details the energy and trace elements of bioaccumulation with the biomass of miscanthus grown on different kinds of technosols. Chapter Four provides characteristics of a khondalitic aquifer. Chapter Five discusses a numerical simulation of the tsunami generated by a potential collapse and submarine landslide in La Palma (Canary Islands) after the September 2021 Cumbre Vieja eruption. This chapter also compares the eruption to the Late Bronze Age eruption of Santorini. Lastly, Chapter Six examines the upper cretaceous succession of the Zagros basin.
