Amountain chain of sedimentary rock may form as a result of a ?
a) divergent boundary of ocean crust and continental crust
b) convergent boundary of ocean crust and continental crust
c) convergent boundary of two continental crusts
d) divergent boundary between two oceanic crusts

The correct answer is - C) Convergent boundary of two continental crusts.

When two continental tectonic plates collide, they form a convergent boundary. They are pushing against each other, and the immense pressure is starting the lift up the land covered with sedimentary rocks. As a result of this, the sedimentary rocks that are gaining on elevation are starting to turn into a mountain chain as they become bigger, thus starting to have sedimentary rocks appear on places that are not typical for them.

Mountain chains that have formed from sedimentary rocks, that have been put under immense pressure because of the collision of two continental crusts can be seen in multiple places around the world. Some of the best known being the Himalayas and the Alps.
