How does mountainous terrain affect settlements in a region all the correct answers 1 groups develop their own cultures and traditions 2 groups trade with each other regularly 3 people travel from settlement to settlement 4settlements are isolated from each other

Humans have inhabited mountains. Obviously, the terrain presents poor infrastructure and limited access to agriculture. Humans there cannot freely travel due to poor terrain or adverse weather, so they cannot trade frequently nor travel from settlement to settlement. However, they still manage to do trade since they will need items like food and stuff they cannot produce in the mountains so they are not isolated. So the best answer is 1 groups develop their own cultures and traditions.
