GEOLOGY

Detailed explanation-1: -A fold that results in an arch shape is a syncline. A fold that has an arch, like the letter A, is an anticline. A normal fault is caused by compression. Compression results when the sides are being squeezed together, resulting in one side moving higher than the other.

Detailed explanation-2: -An anticline is a fold that is arched upward to form a ridge; a syncline is a fold that arches downward to form a trough (Figure ). Anticlines and synclines are usually made up of many rock units that are folded in the same pattern. The tip of a fold is called the nose.

Detailed explanation-3: -Synclines are typically a downward fold (synform), termed a synformal syncline (i.e. a trough), but synclines that point upwards can be found when strata have been overturned and folded (an antiformal syncline).

Detailed explanation-4: -type of fold …is convex upward, and a syncline is a fold that is concave upward. An anticlinorium is a large anticline on which minor folds are superimposed, and a synclinorium is a large syncline on which minor folds are superimposed.

Detailed explanation-5: -In structural geology, an anticline is a type of fold that is an arch-like shape and has its oldest beds at its core, whereas a syncline is the inverse of an anticline.
