Advantage of rock cycle
Explanation:
The rock cycle is the continuous succession of rock formation, erosion and reformation. Its forces have shaped Earth's surface for 4.5 billion years. Its life-giving properties are powered by great convection currents in the mantle causing crustal movements (plate tectonics) that form continents, mountain ranges and ocean basins. With time, the Earth's crust has been altered, reformed and eroded to form igneous, sedimentary and metamorphic rocks.
