If thermal difference in the mantle decreases what will happen to convection strength?

Answer and explanation

Correct answer: It may become weaker

The correct answer is option A: convection may become weaker. The governing concept is the relationship between a thermal gradient and buoyancy-driven circulation. Mantle convection is powered because temperature differences create density differences: warmer material is relatively less dense and rises, while cooler material is denser and sinks. If the temperature contrast decreases, the density contrast and buoyant force also generally decrease, so the circulating movement can lose strength. The wording “may become weaker” is appropriate because convection also depends on viscosity, pressure and other physical conditions. The other choices describe unrelated transformations, not a change in convection intensity.
