Hy dear here is your answer:-

Here is the reason why, many mountain trees are cone-shaped having sloping branches :-

The conical shape of coniferous trees prevent too much snow accumulating on the tree and helps to get the snow to fall off the tree quickly and get sunlight. Less snow accumulation facilitates in preserving the tree sturdy and lessens the spoiling of leaves.

The conical shape of conifer trees (mountain) prevents as much accumulation of snow as there would be on a wider shaped tree.

The conical shape of the tree also helps to get the snow to fall off the tree quickly and to get the sunlight.
