Learning outcomes of the course unit
The first part of the course deals with the main physical processes affecting the earth surfaces in order to understand the different clymatic condictions affecting the different regions of the earth surface. In the second part of the course the main different methods for maps construction are considered.
The course provides knowledge useful for understanding the phenomena that develop in the natural environment. The course includes main topics of astronomy, meteorology and geomorphology closely related and useful for the student to correctly interpret natural phenomena. The topographic map is an important tool for the interpretation of the landscape and essential to recognize the main processes.
Course contents summary
The Earth shape. The Earth rotation and revolution. Solstices and equinoxes.Sideral and solar day.. The structure of the atmosphere. The solar radiation. Air temperature. Atmosphere pressure. The winds and the atmospheric circulation. The atmospheric moisture.Air masses, fronts and middle latitudes cyclones. The Koppen and Strahler clymatic clssifications.
The first part of the course provides knowledge about the main astronomical motions of the Earth and consequent illumination of the globe. The second part describes the main characteristics of the atmosphere and meteorological phenomena. The third part concerns the distribution and classification of climates on Earth. Finally, the course includes a description of the criteria for implementation, interpretation and use of the topographic map.

Assessment methods and criteria
The obtained grade is mediated by the marks obtained in the Cartography practice test and in the GIS practice test.
The student should have acquired the basic concepts of physical geography, understand natural, astronomical and meteorological phenomena and be able to link together such knowledge; the student would have understood the distribution of climates on Earth. The student should also have acquired the knowledge to interpret a topographical map.
