LESSON 2
SOIL EROSION
Embedded Files
It is the movement of soil and rock fragments. It is the transfer of rock fragments and soil from place to another. Erosion of rock fragments contributes to soil formation and landform formation in general.
Water carries rock and soil particles from one location to another as it flows. The fast movement of water can cause many sediments to be carried away by the water.
When the wind blows, it carries light material and soil particles with it, transporting and depositing them somewhere else. Wind has the ability to move and carry away soil particles.
Some rocks and soil particles stick to the bodies of burrowing animals as the move from one place to another, resulting in sediment transport. When animals travel around, they break down rocks with their claws and hooves, and their waste materials help in the decay that cause soil erosion.
We cannot deny that humans play a significant role in the rate at which soil erosion occurs. Even walking contributes to soil erosion because soil clings to shoes, in the same way that it does to animals, and the soil is then transported from place to place.

SOIL EROSION AND CONSERVATION
WAYS OF PREVENTING SOIL EROSION
WAYS OF PREVENTING SOIL EROSION
Contour Plowing
it is the process done by farmers in making furrows, following the shape of the slope of the hill.
Soil Tilling
the farmers till the land once or twice a year only to make the soil more fertile and good for planting.
Terracing
one of the most famous terraces in the world is the Banaue rice Terraces. It is one of the eight wonders of the world.
Strip cropping
it is a process of growing tall and short crops in alternate strips to break the wind.
Crop Rotation
is a farming practice where crops planted are different every planting season. In this way, the soil nutrients are being replenished.
