Step-by-step explanation:
- The word isos and Stacy are derived from the Greek word and they mean the standstill and are in balance and is a state of the gravitational equilibrium between the earth crusts.
- And this concept explains the occurrence of the variation in the heights of the earth's crust landmass and it's said to be in equilibrium when a certain area of the surface reaches that state.
- It's an important way to explain the negative feedback mechanism of the system.
