Man-made structures are buildings and constructions created by humans to serve various purposes. These can include homes, schools, bridges, and skyscrapers. Each structure is designed to meet specific needs, such as providing shelter, facilitating transportation, or creating spaces for work and leisure. Examples of famous man-made structures include the Eiffel Tower in Paris and the Great Wall of China. These structures often reflect the culture and technology of the time they were built. For instance, modern skyscrapers use advanced materials and engineering techniques, while ancient structures like the Colosseum in Rome showcase the ingenuity of past civilizations. Man-made structures shape our environment and influence how we live.
