Compilation of fundamental parameters of earth

Abstract

Earth is a unique planet in the universe characterized by a stable crust and a dynamic internal environment, fostering intelligent life. Studying Earth not only aids in understanding our habitat but also helps uncover mysteries of other celestial bodies. Earth parameter data are essential for a comprehensive understanding of the planet. Here we compile and update key data on Earth's fundamental parameters, historical evolution, and the current geophysical parameters and geochemical compositions of its atmosphere, water, crust, mantle, and core. The data are sourced from a combination of historical records, satellite observations, and recent field studies, and have been validated using established geophysical and geochemical methodologies. We specifically examine the elemental compositions of various Earth layers and offer recommended values for certain datasets, aiming at easier accessing fundamental Earth data, thereby facilitating deeper exploration of Earth sciences.
