1- Earthquake, 2-younger and 3- Andes

Explanation:

Earthquake refers to the sudden shaking of the earth due to the propagation of seismic waves within the crust. It occurs due to the plate tectonic movement and it is not a force, therefore it does not lead to the formation of mountains.

The North American Eastern mountains were formed about 480 million years back, whereas the Western mountains are about 50-170 million years old. Thus, the western being younger.

The Andes mountains were found to be stopped growing due to the rapid erosion of the mountain by wind, water and ice.

Thus, the correct answers are mentioned above.
