Terracing is a method to produce flat land on slopes. It can make agriculture easier, and can potentially help control erosion.
Soil erosion on hill slopes can be checked by contour ploughing.
terracing grows some vegetation which helps slow down erosion

The hill slopes steeply away from the road in this area. Let's hit the slopes! (Let's go skiing!)
The Inca needed to terrace to be able to do much farming. The slopes were too steep and the soil would erode without the terracing.

Terraces significantly reduce the rate of soil erosion on slopes.
[1] The Inca Empire was known for its terracing of mountain slopes. One reason for terracing was increased farmland. The other was steepened slopes, against invaders. [2] A beautifully perfect example of terracing may be seen in Peru, at Machu Picchu, which means Old Peak. [We know the language of the Inca Empire as Quechua. But native speakers called it Runa Shimi, or Language of the people. The word Quechua actually is an insult. But the Empire's enemies considered the Inca thieves. And so that was the term that was passed on to the Spaniards, and to posterity.]
