Hey friend,
Here's your answer,
First, let us know what is soil:
Soil is a mixture of small particles of rocks and humus.
WHAT INFLUENCES THE FORMATION OF SOIL ?
Temperature variations due to
• Radiations of the sun
• Rain
• Water
• Winds
• Living organisms
The formation of soil involves two processes:
♠ Weathering
♠ Paedogenesis
HOW IS SOIL FORMED?
Breakdown of bigger rocks into small, fine particles is called weathering. It may occur due to physical, chemical or biological means.
In the influence of radiations coming out from the sun, rocks heat up and expand. At night, these rocks cool down and contract.
Since, all parts of rocks don't undergo expansion and contraction at the same rate, cracks begin to appear in the rocks and ultimately the large rocks breakdown into smaller portions.
♠ Water that is flowing or falling also has an erasing effect on the rock particles.
On freezing, the water expands in rock fissures and break the rocks.
♠ Strong winds continue to rub against hard rocks and erode them.
♠ Growth of mosses, lichens and other plants also influence the formation of soil by eroding the rocks over which they are growing.
Hope this helps!!!!
