The term "Dynamic Earth" refers to the constantly changing nature of our planet. This includes processes such as plate tectonics, which involves the movement of the Earth's crust, leading to earthquakes and the formation of mountains. Additionally, the Earth's atmosphere and oceans are in constant motion, influencing weather patterns and climate. Another aspect of a dynamic Earth is the rock cycle, where rocks are formed, broken down, and reformed over time. This cycle is driven by natural forces like erosion and volcanic activity. Understanding these processes helps scientists study the Earth's history and predict future changes.
