Why is farming in mountainous areas so difficult without terracing? a. poor soil quality of mountainous land b. rugged landscape of mountainous land c. lack of human resources in mountains d. lack of animal labor in mountains

b. rugged landscape of mountainous land.

The reason why farming is so difficult in montainous areas is the rugged landscape of mountainous land. This means that the land is difficult to irrigate, and that surface runoff is very high. Moreover, the erosion of the land is a big problem. A solution that farmers have come up with is that of terracing. Terracing is the creation of flat land on mountains, in a way that resembles a set of stairs. Terracing addresses these problems and facilitates agriculture in these rugged areas.
