The history of terraces
3. So why did these people go to so much trouble to turn the entire mountains into terraces Firstly, there are few large, flat areas of land in the region. Building the terraces therefore meant that they could increase the areas in which they could grow rice. Secondly, although the region has plenty of rain, the mountains are steep and the soil is shallow. The flat terraces catch the rainwater and prevent the soil from being washed away.
A. The vapour forms clouds.
B. The sun heats the water.
C. The rain moves down onto the mountain terraces again.
D. Rainwater moves down the mountains and into the terraces.
E. The water turns into vapour.
