The conceptions about the origins of mountains, faults, folds or relief are very different if we compare didactic books of Geog-raphy published before and after the elaboration of Plates Tectonics theory. In this article, it was analyzed didactic books from first grade education, which is currently equivalent to the 6th grade of Elementary School 2, published between 1933 until 1961. Obviously, within this article, Plate tectonics theory had not yet been elaborated. However, the academic world was already fa-miliar with the Continental Drift theory, an innovative proposal elaborated at the beginning of the 20th century by German sci-entist Alfred Wegener (1880-1930). According to Wegener, the continents were together millions of years ago, forming a single great mass, called by him of "Pangea". Considering that the books analyzed were published between 1933 and 1961, such works could be expected to contemplate and explain the continental drift theory. However, it was not what it was observed. In addition, the formation of mountains, folds, faults or relief had very different conceptions of what today's students learn.
