Physical processes are the natural actions and changes that occur in the world around us. These processes can include things like weather patterns, the water cycle, and geological formations. They help shape our environment and influence how we live. For example, the water cycle describes how water evaporates, forms clouds, and falls back to the ground as rain, which is essential for all life. Another important aspect of physical processes is how they interact with energy. Photosynthesis in plants is a physical process that converts sunlight into energy, allowing them to grow. Similarly, erosion is a process where wind or water wears away rocks and soil, changing landscapes over time. Understanding these processes helps us appreciate the complexity of our planet.
