7 Arock type will be gneiss.
7 C Dolomite are consider to be less slouble than limestone.This is because the dolomite has the mohs hardness ranges from 3.5 to 4 and the limestone has hardness of 3.
7.D Option B And Option D are the correct one Squeezing behaviour and Flowing behaviour as in this rock is being jointed as well as fractured.
7F. 1.The rock will experience deformation due to high strain.
2.The geometry and orientation of the mineral grains will be changed.
3.thickness may be vary due to faulting and displacement of strata.
8A. C. Obtain rock samples and perform unconfined compression strength test.
