Answer:
The steps prevented soil from washing away and made it easier to irrigate crops.
The steps increased the amount of land that farmers could grow crops on.
Explanation:
Terrace farming primary benefit is to reduce the speed of run off water which leads usually lead to erosion therefore conserving land and water.
It is method of farming carried out in mountainous region,where the sloppy nature of the mountain and the effects of acceleration due to gravity(g),increases the velocity of rain water washing the top soil on the mountain,removing the top soil and therefore washing away the nutrients as wastes.
To reduce the rate of velocity,terraces are built on the slope of the mountain,therefore protecting the topmost soil layer from been washed away by erosion,thus the soil fertility is conserved, and crops could be grown on the terrace. Therefore by allowing the use of sloppy land area of the mountain for farming ,terrace farming increases the land that the farmers could used for crops propagation.This would have been impossible without the creation of the terraces.
In addition, since the grassed water ways are not needed for water supply there is maximum land area available for farming.
Answer: army.
Explanation: I looked it up and that's all it showed.
Desalinization makes it easy for people to live in areas with only salt water but no fresh water.
Desalinization is a technique of water purification that has to do with the removal of salt from a substance such as sea water. The process of desalinization could involve:
- evaporation
- Electrodialysis
- reverse osmosis
- Freezing
The removal of salt from water through this process, makes the water safe for drinking and usage.
