The atoms of the solid have to form a crystalline structure, which means that they have an ordered configuration that is the same throughout the entire solid.
we have
work done (W)= force(F) × displacemen(s)
or, 80= F× 8
or, F= 10 N
therefore, 10 N force is required to lift the rock.

ANDESITE is a fine grained rock that formed when magma irrupt it onto the surface and crystallized quickly ANDESITE & DIORITE have a composition that is intermediate between basalt.This is because their parent magmas formed from the PARTIAL melting of a BASALTIC oceanic plate.
