Plate tectonics is a fundamental concept in modern geology education in both Brazil and the United States. In Brazil, it is typically introduced in secondary school earth science (Ciências da Terra) and is essential for understanding the country's geological features, including the Amazon basin and coastal mountain ranges. In the USA, it is a cornerstone concept in earth science curricula. The theory revolutionized geological understanding in the 1960s and remains central to explaining natural disasters and geological phenomena.
