18) Fold axis is non-plunging fold.
Because the thickness of the beds are equal. If the fold is plunging then the thickness of beds will be unequal. So the fold is non-plunging fold.
19) The structure in the map is non-plunging syncline. Because the thickness of beds are eqaul which denotes non-plunging fold and dip direction of beds is towards inner portion of beds. So, the fold is syncline.
20) The factors which determines from this type of structure are "a" and "b" ( answer option d). Those are a) the shape of the different layers and the strike and dip symbols and b) the age relationship (oldest on the outside, youngest on the inside).
21) This structure results from compression stress. Compressional stress acts on the body which form folding.
22) This type of structure is formed in convergent plate boundary. Because two plate moves each other and due to compressional stress it form folding.
23) The fold is an example of ductile(plastic) strain.
