What effect do mountains have on storm activity? a. mountains storms move with the wind. c. mountains are large enough to shelter the lowlands. b. mountains stop storms from moving with the wind. d. mountains have no effect on storm activity.

The correct answer is b. mountains stop storms moving with the wind.

Mountains are representing a natural barrier when it comes to the movement of air masses, especially the higher mountains. They very often block the movement of the storms with the winds, and practically block their way, so the storms instead of moving further beyond the mountains, they are building up on their sides and release their full power in here. There's exceptions of course, and as I said, this is the effect of the higher mountains and mountains with mid height, while the lower mountains are only partially able to have this effect.
