How were mountains formed?

Mountains ⛰are formed in two ways. When the tectonic plates move, they collid against each other. When the heavy oceanic part of plate collides with the continental part, it submarges below it. The Andes,for instance, were formed in this way. The other way is when two continents collide with each other, the plates bend at the point contact and fold up sleepy.The Himalayas or the alps were formed in this way around 35 million years ago and are counted among the 'young ' Mountains ⛰of the world. Old Mountains, such as Black Forest or the Harz mountains, are lower ranges because peaks have been worn down by rain, 🧊, and wind over time ⏲️😀😄😳😉.............
