How is soil formed?

$\huge{\underline{\boxed{\mathbb{answer}}}}$

Soil is a mixture of organic matter, minerals, gases, liquids, and organisms that together support life. Earth's body of soil, called the pedosphere, has four important functions:

as a medium for plant growth

as a means of water storage, supply and purification

as a modifier of Earth's atmosphere

as a habitat for organisms

All of these functions, in their turn, modify the soil and its properties.

The pedosphere interfaces with the lithosphere, the hydrosphere, the atmosphere, and the biosphere.[1] The term pedolith, used commonly to refer to the soil, translates to ground stone in the sense "fundamental stone."[2] Soil consists of a solid phase of minerals and organic matter (the soil matrix), as well as a porous phase that holds gases (the soil atmosphere) and water (the soil solution).[3][4][5] Accordingly, soil scientists can envisage soils as a three-state system of solids, liquids, and gases.[6]

Soil is a product of several factors: the influence of climate, relief (elevation, orientation, and slope of terrain), organisms, and the soil's parent materials (original minerals) interacting over time.[7] It continually undergoes development by way of numerous physical, chemical and biological processes, which include weathering with associated erosion. Given its complexity and strong internal connectedness, soil ecologists regard soil as an ecosystem.[8]

Most soils have a dry bulk density (density of soil taking into account voids when dry) between 1.1 and 1.6 g/cm3, while the soil particle density is much higher, in the range of 2.6 to 2.7 g/cm3.[9] Little of the soil of planet Earth is older than the Pleistocene and none is older than the Cenozoic,[10] although fossilized soils are preserved from as far back as the Archean.[

Answer 2

Answer:

1. Soil is formed by a process called weathering of rocks. It would require a millions of years to form a little soil. The factors responsible for it is temperature or heat of the sun, Cracks formed in rocks due to rain and heat, parent rock, climatic changes happened.

2. Soil erosion is the washing away of the topmost layer of soil due to rain water, wind etc.

3. Planting more and more trees that is afforestation. The roots of trees can prevent soil from being washed away.
