GEOLOGY

Detailed explanation-1: -Fold mountains are created where two or more of Earth’s tectonic plates are pushed together. At these colliding, compressing boundaries, rocks and debris are warped and folded into rocky outcrops, hills, mountains, and entire mountain ranges. Fold mountains are created through a process called orogeny.

Detailed explanation-2: -The Important two-fold which we usually see in the mountains are anticline and syncline. One fold is convex-shaped upwards and another has downwards.

Detailed explanation-3: -There are two types of fold mountains: young fold mountains (10 to 25 million years of age, e.g. Rockies and Himalayas) and old fold mountains (over 200 million years of age, e.g. Urals and Appalachians of the USA).

Detailed explanation-4: -The Appalachian Mountains, along with the Caledonide Mountains in Greenland, the British Isles and Scandinavia, as well as the Atlas Mountains in northeastern Africa, are parts of a continental collision zone that formed 500 to 300 million years ago.

Detailed explanation-5: -Fold mountains-Fold mountains are formed when two plates run into each other or collide. Fault-block mountains-Fault-block mountains are formed along faults where some large blocks of rock are forced upwards while others are forced down. More items
