The Earth is a living planet that has undergone countless changes during its long history of thousands of millions of years. These events have left their mark on its surface, its skin. The geological map is a classic scientific research tool that analyzes the current arrangement of different geological materials: rocks and sediments on the Earth's surface, which allows us to know what the Earth is today, recall its history of 4,500 million years and predict what it will look like tomorrow. The geological map informs us about the materials that outcrop on the surface and their arrangement in depth. In other words, this map is a representation of the geological architecture, the soil and the subsoil. In this way, the map becomes an indispensable tool for land use planning, geological risk control, research and management of mineral resources, including groundwater, metals and energy sources such as coal and oil. These maps also play an essential role in planning agricultural work. This video shows the process of developing a geological map: information from previous researchers, data collection in the field, office work, digitalization and finally editing the maps. Additional activities such as determining the age of rocks or generating three-dimensional models that allow us to reconstruct the structure of the Earth beneath our feet are also explained.
