3, rock that bends and doesnt return to its original shape is....\noductile\nconductive\nbrittle\ncongruent\n…

Brief Explanations:

• For question 3, ductility is the property of a material to deform permanently under stress without breaking. A rock that bends and doesn't return to its original shape shows ductility. Conductive refers to the ability to conduct electricity or heat, brittle means it breaks easily without much deformation, and congruent is a geometric - related term not applicable here.
• For question 4, an anticline is an upward - arching fold in rock layers. A decline is a general term for a downward trend, an incline is a sloping surface, and a syncline is a downward - curving fold.

Answer:

3. A. ductile
4. B. anticline
