As I was reading through one of the websites, I happened to come across this sentence.

Wegener's explanation was that as the continents moved, the leading edge of the continent would encounter resistance and thus compress and fold upwards forming mountains near the leading edges of the drifting continents.

Could u please simplify this for me?

If a plate is moving NW and it runs into a plate that is moving S or SE (or whatever), there will be a collision of some kind. Think about what happens when a car's fender hits a pole. What happens to the fender?

Oh ok, could u provide me with a picture on a site that sort of explains/shows leading edges of continents folding upwards forming mountains.

There are many here:

Thank you both very much:)

Certainly! According to Wegener, a German scientist, his explanation for the formation of mountains was that as the continents moved over time, the front part of the continent would face resistance. This resistance would cause the continent to compress and fold upwards, resulting in the formation of mountains near the leading edges of the drifting continents. In simpler terms, as the continents constantly shift and collide with each other, it creates pressure that causes the land to fold and create mountains.
