What does the lesson suggest about the movement of soil and rock? It helps distribute nutrients across the Earth's surface It should be completely stopped It only happens because of human activity It only occurs in mountainous regions

The lesson suggests that the movement of soil and rock plays a vital role in distributing nutrients across the Earth's surface, promoting healthy ecosystems. Natural processes like erosion, weathering, and sedimentation contribute to this dynamic, ensuring that vital minerals and organic materials are available to plants and animals alike, enhancing biodiversity. While human activities can significantly affect soil and rock movement—often leading to detrimental effects like increased erosion and habitat loss—this movement is largely a natural phenomenon. It occurs in various landscapes, not just mountainous regions, reflecting the Earth's ever-evolving processes. Embracing this natural cycle is essential for maintaining ecological balance.
