Answer:
Viscosity directly affect the speed of convictions.
Explanation:
The speed of convection in Earth’s mantle, oceans, and atmosphere also depends on the viscosity of the fluids. If the viscosity of fluids is higher so it takes more time to complete the process of convection in Earth’s mantle, oceans, and atmosphere, while on the other hand, if there is lower viscosity of fluids, the conviction in the mantle, oceans, and atmosphere of earth occur in high speed due to easily movement from place to place.
