Excavation sites are locations where archaeologists or construction workers dig into the ground to uncover artifacts, fossils, or other materials. These sites can reveal important information about past civilizations, geological formations, or buried structures. Excavation is often conducted carefully to preserve the context of the findings. In archaeology, excavation sites may include ancient cities, burial grounds, or historical landmarks. Tools like shovels, trowels, and brushes are used to carefully remove soil and debris. Notable excavation sites include Pompeii, Stonehenge, and Machu Picchu, each providing valuable insights into human history and culture.
