You also get fold mountains where two continental plates collide.
Give one way that humans use fold mountain areas.
Farming Hydro-electric power Mining Forestry Tourism
Describe how farmers have adapted to the steep slopes in fold mountain areas.
Higher mountain slopes aren’t great for growing crops so they’re used to graze animals.
Lower slopes are used to grow crops.
Steep slopes are sometimes terraced to make growing crops easier.
Name one range of fold mountains.
Describe three ways humans use the area.
Describe how people have adapted to the conditions of the area.
The Alps.

Steep Relief - Goats are farmed there because they’re well adapted to live on steep mountains.
Poor Soils - Animals are grazed in most high areas as the soil isn’t great for growing crops.
Limited Communications - (no space)
