In agriculture, a terrace is a piece of sloped plane that has been cut into a series of successively receding flat surfaces or platforms, which resemble steps, for the purposes of more effective farming. This type of landscaping is therefore called terracing.
Q. How does terracing prevent and control soil erosion on hilly areas?
How does the terracing shown in Figure 1 photo prevent soil erosion? Terracing keeps the soil from moving very far downhill since it will only get as far as the next terrace downhill. Water will also be slowed by the terraces and so will be less able to carry tremendous amounts of soil downhill.

Q. Which farming practices reduce soil erosion?
Some common soil-saving practices include the following. Crop rotations using high residue crops (corn, hay, and small grain) produce large amounts of residue that help control erosion. No till planting reduces erosion by keeping more resi- due on the soil and less soil disturbance.
Q. What are the benefits of terraces?
How do terraces improve water quality and soil erosion? Terraces reduce slope length, reducing the power of flowing water to erode soil. By limiting soil erosion, terraces also improve water quality by reducing sediment and phosphorus delivered to streams, rivers, and lakes.
Q. Where is terracing mostly used?
It is commonly used in Asia by rice-growing countries such as Vietnam, Philippines, and Indonesia. In fact, the terraces of rice found in the Philippine’s Cordilleras have been acknowledged as a UNESCO World Heritage Site. Apart from rice cultivation, terraces are also used to grow rice, potatoes, and maize.
Q. How do Terraces work?
Terraces are earthen structures that intercept runoff on moderate to steep slopes. They transform long slopes into a series of shorter slopes. Terraces reduce the rate of runoff and allow soil particles to settle out. The resulting cleaner water is then carried off the field in a non-erosive manner.
Q. What are the two powerful agents of soil erosion?
The agents of soil erosion are the same as the agents of all types of erosion: water, wind, ice, or gravity. Running water is the leading cause of soil erosion, because water is abundant and has a lot of power. Wind is also a leading cause of soil erosion because wind can pick up soil and blow it far away.
Q. What are 2 factors that affect the rate of erosion?
Climate, soil properties, vegetation, soil cover, and land management practices are factors that influence both water and wind erosion.
