8. Guttenberg discontinuity is found between the

• Mantle and Core
• Crust and Mantle

10.  Given below are the two statements, one labelled as Assertion (A) and other labelled as Reason (R).

Assertion (A): Stable air resists vertical movement and unstable air ascends freely because of its own buoyancy.

Reason (R): When stable air is forced aloft the clouds that form are widespread and have little vertical thickness.

In the context of the above two statements, which one of the following is correct?

• (A) is correct but (R) is wrong.
• (A) is wrong but (R) is correct.
• Both (A) and (R) are correct.
• Both (A) and (R) are wrong
