They contain a combination of both anticlines and synclines.

The crust breaks into large chunks to form a series of sharp peaks.

The folds can bend upward and form mountains.

Detailed explanation-1: -Fold mountains are formed when sedimentary rock strata in geosynclines are subjected to compressive forces. They are the loftiest mountains, and they are generally concentrated along continental margins. Fold mountains belong to the group of youngest mountains of the earth.
Detailed explanation-2: -Detailed Solution. The correct answer is Andes mountain.
Detailed explanation-3: -The movement of the two plates forces sedimentary rocks upwards into a series of folds. Fold mountains are usually formed from sedimentary rocks and are usually found along the edge of the continents. Example. Himalayan Mountains in Asia, The Alps in Europe.
Detailed explanation-4: -Many folds are distinctly linear; that is, their extent parallel to the axis is many times their width. Some folds, however, are not linear but are more or less circular in plan. A dome is such a fold that is convex upward; this means that its strata dip outward from a central area.
