Final answer:
The rate of lithosphere production roughly balances with the rate of lithosphere destruction due to plate tectonics.
Step-by-step explanation:
The rate of lithosphere production roughly balances with the rate of lithosphere destruction due to the process of plate tectonics. Plate tectonics is the theory that explains how the Earth's lithosphere is divided into several large and small plates that move and interact with each other. As new crust is formed at divergent plate boundaries, old crust is destroyed at convergent plate boundaries through subduction. This continuous cycle of creation and destruction ensures that the rate of lithosphere production roughly matches the rate of lithosphere destruction.
