Detailed explanation-1: -terrace cultivation, method of growing crops on sides of hills or mountains by planting on graduated terraces built into the slope. Though labour-intensive, the method has been employed effectively to maximize arable land area in variable terrains and to reduce soil erosion and water loss.

Detailed explanation-2: -Terrace farming is the process of cultivating crops on the sides of hills or mountains by planting on graduated terraces carved into the slope, or in other words, the practice of carving flat regions out of hilly or mountainous terrain to produce crops.

Detailed explanation-3: -Step farming is also known as terrace farming. Terraces or steps is built on slopes of hills and mountains. Contour farming means following the natural contours when tilling the soil, planting and cultivating. Farmers plant crops across or perpendicular to slopes to follow the contours of a slope of a field.

Detailed explanation-4: -Terrace farming is basically done in hilly or mountain areas because hilly areas are more liable to soil erosion and overflow of water. It has been made on steep slopes so that plane surfaces are used to grow crops.

Detailed explanation-5: -Step farming or terrace farming is common in hills to check soil erosion through water current on the slopes. It provides a physical barrier to soil erosion by water. The mountain is made into steps that slows down the speed of rainwater preventing damage to crops.
