Mountain soils occur in the highland areas of the north and west, and are residual as well as transported. along the steep crests and slopes, and in the broken hill country, shallow residual soils have developed. under arid and semi-arid conditions, these soils are usually strongly calcareous, with low organic content. further north, under sub-humid conditions, there is more leaching, and a higher organic content.
In the mountain valleys, soils are formed from the alluvial infills of the streams. these soils are calcareous silt loams and sandy loams of low organic content. they are cultivated in patches only.

There are various types of soil that undergo diverse environmental pressures. soil is mainly classified by its texture, proportions and different forms of organic and mineral compositions.
The first type of soil is sand. it consists of small particles of weathered rock. sandy soils are one of the poorest types of soil for growing plants because it has very low nutrients and poor water holding capacity, which makes it hard for the plants roots to absorb water. this type of soil is very good for the drainage system. sandy soil is usually formed by the breakdown or fragmentation of rocks like granite, limestone and quartz.
Silt, which is known to have much smaller particles compared to sandy soil and is made up of rock and other mineral particles, which are smaller than sand and larger than clay. it is the smooth and fine quality of the soil that holds water better than sand. silt is easily transported by moving currents and it is mainly found near the river, lake and other water bodies. the silt soil is more fertile compared to the other three types of soil. therefore, it is also used in agricultural practices to improve soil fertility.
Clay is the smallest particle amongst the other two types of soil. the particles in this soil are tightly packed together with each other with very little or no airspace. this soil has very good water storage qualities and makes it hard for moisture and air to penetrate into it. it is very sticky to the touch when wet, but smooth when dried. clay is the densest and heaviest type of soil which does not drain well or provide space for plant roots to flourish.
Loam is the fourth type of soil. it is a combination of sand, silt and clay such that the beneficial properties from each is included. for instance, it has the ability to retain moisture and nutrients hence, it is more suitable for farming. this soil is also referred to as an agricultural soil as it includes an equilibrium of all three types of soil materials being sandy, clay, and silt and it also happens to have humus. apart from these, it also has higher calcium and ph levels because of its inorganic origins.
The ground on which we walk is never quite the same it keeps on changing. sometimes, it is made up of millions of tiny sand granules and other times it is a hard, rocky surface. other places have the ground covered with moss and grass. when humans came along, the landscape slowly changed with the introduction of roads and rails.
Soil can be classified into three primary types based on its texture 8211 sand, silt and clay. however, the percentage of these can vary, resulting in more compound types of soil such as loamy sand, sandy clay, silty clay, etc.
Sandy soil essentially consists of small particles formed by weathering rocks. it is also very low in nutrients and poor in holding water, which makes it one of the poorest types of soil for agriculture.
Silt has smaller particles compared to sand. it is also made up of rock and other mineral particles. furthermore, its fine quality holds water better than sand. due to the above-mentioned features, it is also beneficial for agriculture.
Thar desert, also called great indian desert, arid region of rolling sand hills on the indian subcontinent. it is located partly in rajasthan state, northwestern india, and partly in punjab and sindh sind provinces, eastern pakistan.
The thars desert sands overlie archean early precambrian gneiss metamorphic rocks formed between 4 billion and 2.5 billion years ago, proterozoic later precambrian sedimentary rocks formed about 2.5 billion to 541 million years ago, and more-recent alluvium material deposited by rivers. the surface consists of aeolian wind-deposited sand that has accumulated over the past 1.8 million years.
The desert presents an undulating surface, with high and low sand dunes separated by sandy plains and low barren hills, or bhakars, which rise abruptly from the surrounding plains. the dunes are in continual motion and take on varying shapes and sizes. older dunes, however, are in a semi-stabilized or stabilized condition, and many rise to a height of almost 500 feet 150 metres above the surrounding areas. several playas saline lake beds, locally known as dhands, are scattered throughout the region.
