Q. Assertion [A]: Convection currents leads to the movement of fluids from one place to another in a cyclical manner.

Reason [R]: The cyclical movement of fluids is a result of temperature and density differences of the fluid in the Earth's mantle and core.

Read the following statements about convection currents and select the option that is true.

1. Both A and R are true and R is the correct explanation of A
2. Both A and R are true but R is the incorrect explanation of A
3. A is true but R is false
4. Both A and R is false
