The folds in the photograph above were caused by compression at a thrust fault or a convergent plate boundary. Compression usually occurs where two tectonic plates converge or collide. The compression will cause rocks to fold upwards and this upward folding over time can lead to the formation of extensive fold mountains. Examples of fold mountains include the Alps, Andes, and the Himalayas.

Answer:
Stratigraphy and Biostratigraphy.
Explanation:
Relative dating is a method of determination of age, in which one object or organism is compared with the other object or organism found in the heap of strata. It is a method for determining the relative order of the past events, without stating the absolute age.
Stratigraphy is a branch of geology that studies the relative position of the sediments and rocks in the strata with respect to the geological timescale. Biostratigraphy is the branch of stratigraphy which deals with the relative aging of fossils with respect to the strata in which these are found defining a particular period of geological time scale.
They classify on how they reproduce.
