This resource explores the concept of human modifications to landscapes, specifically focusing on terrace farming and dikes. Students will analyze how engineering structures such as terrace walls and dikes alter physical landscapes to overcome environmental limitations like gravity and flooding. The document includes structured observation activities guiding students to analyze physical features and their implications for sustainability. It also engages students in comparative analysis, prompting them to explain how terrace farming in mountainous regions and dikes in low-lying areas manipulate natural forces to create arable land. A challenge task encourages students to consider environmental impacts related to these modifications, fostering critical thinking and self-assessment on their understanding of the topic.
