Edizione unica

Primo semestre
All lectures will take place synchronously on the TEAMS platform and will be recorded. There will be organized also two face-to-face lectures to be held in open-air at the Botanical Garden of the University of Milan in compliance with the regulations imposed to contain the spread of Covid-19.

Exams will be held in compliance with the Covid-19 containment regulations. All course material and infos relating to Covid-19 containment will be published on the Ariel web page of the course and on
Discussion on the physical prerequisites to simple and complex life. Evolution of the earth and the solar system: the first 500 million years; stabilization of the earth system and structuring of Earth in interconnected 'spheres'; birth of modern plate tectonics and the carbon cycle; description of the long-term carbon cycle and of the Earth's natural thermostat; how does the earth keep liquid water on its surface? Climate variability and extreme climates compared: snowball Earth and the Early Eocene Climatic Optimum. Birth of oxygen: the Great Oxygenation Event and the Neoproterozoic Oxygenation Event. Earth's magnetic field and its shielding effects on the Earth's hydrosphere and atmosphere. Catastrophism as the engine of evolution: the K/T boundary limit and the P / T boundary. Evolution and history of the human species. Final discussions: from chondrites to the Anthropocene.
Metodi didattici
Teaching will take place through classic frontal (teacher-student) lectures (to be held online on the TEAMS platform). Flipped classroom sessions with student presentations are also organized.
