Is there a relationship between where the major mountain ranges are and plate boundaries?

Yes, there is a relationship between major mountain ranges and plate boundaries. Mountain ranges are often formed at convergent plate boundaries, where tectonic plates collide and create intense geologic activity that results in the uplift of landmasses and the formation of mountains. Additionally, some mountain ranges can also be associated with transform plate boundaries where tectonic plates slide past each other horizontally, causing the Earth's crust to deform and create mountainous terrain.
