Important components of the soil are mineral particles, humus, water and air. The actual amount of each of these depend upon the type of soil. Question 2 ii. What are the main factors responsible for the formation of soil? Answer: Relief, parent material, climate, vegetation and other life-forms and time are the important factors that affect formation of soil.

Besides these, human activities also influence it to a large extent. For example, the laterite soils develop in areas with high temperature and high rainfall. Black soils are made from volcanoes. Forest soils are formed in the forest areas where sufficient rainfall is available. Peaty soils are found in the areas of heavy rainfall and high humidity, where there is a good growth of vegetation.

Question 2 iii. Mention the class 10th geography chapter 6 ncert solutions mp horizons of a soil profile. Answer: Three horizons of soil profile are:.

Question 2 iv. What is soil degradation? Answer: Soil class 10th geography chapter 6 ncert solutions mp can be defined as the decline in soil fertility, when the nutritional status declines and depth of the soil goes down due to erosion and misuse. Soil degradation is the main factor leading to the depleting soil resource base in India.

The degree of soil degradation varies from place to place according to the topography, wind velocity and amount of the rainfall. Question 3 i. What are black soils? Describe their formation and characteristics. Answer: Black soils are formed by Ncert Solutions For Class 10th Geography Chapter 7 Class volcanoes. Features: The black soils are generally clayey, deep and impermeable.

They swell and become sticky when wet and shrink when dried. So, during the dry season, these soil develop wide cracks. Because of class 10th geography chapter 6 ncert solutions mp character of slow absorption and loss of moisture, the black soil retains the moisture for a very long time, which helps the crops, especially; the rain fed ones, to sustain even during the dry season. Chemical Composition: Chemically, the black soils are rich in lime, iron, magnesia and alumina.

They also contain potash. But they lack in phosphorous, nitrogen and organic matter. The class 10th geography chapter 6 ncert solutions mp of the soil ranges from deep black to grey. In the upper reaches of the Godavari and the Krishna, and the north western part of the Deccan Plateau, the black soil is very deep. Question 3 ii. What is soil conservation?

Answer: Soil conservation is a methodology to maintain soil fertility, prevent soil erosion and exhaustion, and improve the degraded condition of the soil. We can use following measures to conserve soil:. Question 3 iii. How do you know that a particular type of soil is fertile or not? Differentiate between naturally determined fertility and culturally induced fertility.

Answer: The class 10th geography chapter 6 ncert solutions mp red and yellow soils are normally fertile, whereas coarse-grained soils found in dry upland areas are poor in fertility. They are generally poor in nitrogen, phosphorous and humus. Some soils have phosphorus, potassium, humus, nitrogen and calcium naturally.

It increases the fertility of these soils. Such fertility is called naturally determined fertility. On the other hand, if soil is deficient in these substances, such substances are added class 10th geography chapter 6 ncert solutions mp the form of fertilizers and manures. If fertility of soil is increased through human efforts, such fertility is called culturally induced fertility.

Naturally determined fertility makes human dependent on nature. Culturally induced fertility indicates that man has become master of the nature. It is an indicator of development of human race. Soils are living systems. Like any other organism, they too develop and decay, get degraded, respond to proper treatmentif administered in time.

A human being may be intelligent by class 10th geography chapter 6 ncert solutions mp or may be made intelligent by efforts. Similarly, soil may be fertile naturally and may be made fertile by human efforts. Former is called naturally determined fertility and the latter is called culturally induced fertility. Question 1.

Answer: Attempt. Question 2. On an outline map of India, mark the areas covered by the following soil categories. Answer: d Soil. Question 3. Answer: Soil Degradation. Question 4. Which soil is formed by occurrence of volcanoes? Answer: b Black Soil. Question 5. Which soil is made up by the deposition of rivers? Question 6.

Answer: a Northern plains and coastal areas. Question These soils are poor in organic matter, nitrogen, phosphate and calcium, while iron oxide and potash are in excess.

Which soils are these? Answer: c Laterite Soil. Which soils are also called Usara soils? Answer: d Peaty Soil. What percent of India is covered with alluvial soils?

Conclusion:

That equates to from daylight compartment sundown. Similar to houseboat holidays, a propeller powered steam vessel mannequin was invented proof to be additional fit afterwards a paddle circle mannequin?

Water pollution is caused by the discharging of organic and inorganic industrial wastes and affluents into rivers.

This form of pollution is caused by paper, pulp, chemical, textile, dyeing, petroleum refineries, tanneries and electroplating industries. The major solid wastes released into rivers in India are fly ash, phospo-gypsum, and iron and steel slags. Thermal pollution of water is another form of water pollution, caused by the emission of hot water from factories and thermal plants into rivers and ponds.

Iron and steel industry, textile industries and chemical industries require large quantities of water, for their proper functioning. Coal, mineral oil and hydro-electricity are the three important conventional sources of power.

Most of the industries tend to concentrate at the source of power. Nearness to market is essential for quick disposal of manufactured goods. It helps in reducing the transport cost and enables the consumer to get things at cheaper rates. An example is the iron and steel industry which supplies steel to the automobile industry.

How are integrated steel plants different from mini steel plants? What problems does the industry face? What recent developments have led to a rise in the production capacity? Mini Steel Plants are smaller, have electric furnaces, use mainly steel scrap and sponge iron as inputs. They have re-rollers that use steel ingots as well.

They produce mild and alloy steel of given specifications. Problems of Steel Industry:. Solution Ncert Solutions For Class 10th Geography Chapter 4 Text : Industries are responsible for four types of pollution � air, water, land and noise pollution. Following are the various reasons:.
