A terrace is a paved or brick outdoor area right next to a house or apartment. You might have a nice dinner out on your terrace, enjoying the sunset. Terrace and patio are synonyms. Terrace also refers to flat areas on a hillside where people farm or have built houses.
Terrace farming is when farming is done on manmade terraces that have been built into slopes. When humans transform a slope into a series of flat surfaces, they form terraces. Crops are then grown on these flat surfaces rather than on the slope, preventing crops from sliding down the slope over time. The image below is of rice paddies grown on terraces. By building these terraces, water flows down and accumulates in each terrace. If the terraces did not exist, rainfall and water would flow from higher elevations down the hill/mountain, carrying important soil and nutrients with it. Building terraces prevents this from happening.
