Question 15.
Read the case study and answer the following questions:
Unlike the parallels of latitude which are circles, the meridians of longitude are semi-circles that converge at the poles. If opposite meridians are taken together, they complete a circle, but they are valued separately as two meridians. The meridians intersect the equator at right angles. Unlike the parallels of latitude, they are all equal in length. For the convenience of numbering, the meridian of longitude passing through the Greenwich observatory (near London) has been adopted as the Prime Meridian by an international agreement and has been given the value of 0°.
The longitude of a place is its angular distance east or west of the Prime Meridian. It is also measured in degrees. The longitudes vary from 0° to 180° eastward and westward of the Prime Meridian. The part of the earth east of the Prime Meridian is called the eastern hemisphere and, in its west, referred to as the western hemisphere.

(c) acute
(d) reflex
Answer:
(b) right
Question 16.
Read the case study given below and answer any three of the questions that follow.
The destruction of the soil cover is described as soil erosion. The soil-forming processes and the erosional processes of running water and wind go on simultaneously. But generally, there is a balance between these two processes. The rate of removal of fine particles from the surface is the same as the rate of addition of particles to the soil layer. Sometimes, such a balance is disturbed by natural or human factors, leading to a greater rate of removal of soil.
Human activities too are responsible for soil erosion to a great extent. As the human population increases, the demand for land also increases. Forest and other natural vegetation are removed for human settlement, cultivation, grazing animals, and for various other needs. Wind and water are powerful agents of soil erosion because of their ability to remove soil and transport it. Wind erosion is significant in arid and semi-arid regions. In regions with heavy rainfall and steep slopes, erosion by running water is more significant.
Water erosion which is more serious and occurs extensively in different parts of India takes place mainly in the form of sheet and gully erosion. Sheet erosion takes place on level lands after a heavy shower and the soil removal is not easily noticeable. But it is harmful since it removes the finer and more fertile topsoil. Gully erosion is common on steep slopes. Gullies deepen with rainfall, cut the agricultural lands into small fragments, and make them unfit for cultivation.
A region with a large number of deep gullies or ravines is called a bad land topography. Ravines are widespread, in the Chambal basin. Besides this, they are also found in Tamil Nadu and West Bengal. The country is losing about 8,000 hectares of land to ravines every year.

Answer:
(d) 8,000
Question 17.
Name the experts who modified the Nebular Hypothesis. [3]
Answer:
In 1950, Otto Schmidt in Russia and Carl Weizascar in Germany revised the ‘Nebular Hypothesis’, though they differed in details. They were of the opinion that the Sun was surrounded by a solar nebula containing mostly hydrogen and helium along with what may be termed as dust. The friction and collision of particles led to the formation of a disk-shaped cloud and the planets were formed through the process of accretion. However, scientists in the later periods took up the problems of the origin of the universe rather than that of just the Earth or the planets.
Question 18.
Discuss the important gases present in the atmosphere. [3]
Answer:
The important gases present in the atmosphere are:
(1) Oxygen: Oxygen is important for breathing. It is the most combustible gas and it helps in the burning of fuel. Oxygen is the main source of energy and provides a solid base for industries. Oxygen extends up to 64 km but is concentrated at 16 km.
(2) Carbon dioxide: it is the heaviest gas and is confined to lower layers. Carbon dioxide can be found up to a height of 32 km. Though it is present in negligible quantity, it is important for vegetation. Carbon dioxide is meteorologically a very important gas as it is transparent to incoming solar radiation but opaque to outgoing terrestrial radiation. It absorbs a part of terrestrial radiation and reflects back some part of it toward the Earth’s surface. It is largely responsible for the greenhouse effect.
(3) Nitrogen: Nitrogen has no color, odor, or taste. Nitrogen generates protein in plants, which is the main source of food. Nitrogen extends up to 128 km. The atmosphere is composed of 78% nitrogen.
(4) Hydrogen: Hydrogen is a light gas and extends up to 11 km over heavier gases. It accounts for 0.01% of our atmosphere.
Question 19.
Explain the process of the hydrological cycle. [3]
Answer:
The hydrological cycle, is the circulation of water within the Earth’s hydrosphere in different forms, i.e., liquid, solid, and gaseous phases. It also refers to the continuous exchange of water between the oceans, atmosphere, land surface, subsurface, and organisms. About 71% of the planetary water is found in the oceans. The remaining is held as freshwater in glaciers and ice caps, groundwater sources, lakes, soil moisture, atmosphere, streams, and within life. Nearly 59% of the water that falls on land returns to the atmosphere through evaporation from over the oceans as well as from other places. The remainder runs off on the surface, infiltrates into the ground or a part of it becomes a glacier.
Question 20.
What is an annual range of temperature? Explain it with the help of an example. [3]
Answer:
The difference between the maximum average temperature and a minimum average temperature of a place over twelve months is known as the annual range of temperature. Example: The maximum average temperature at Jodhpur is 33.9°C and the minimum average temperature is 14.9°C. Hence, the annual range of temperature at Jodhpur is 19°C (33.9°C-14.9°C).
Question 21.
What is a disaster? What are its two types? [3]
Answer:
Disaster is an undesirable occurrence resulting from forces that are largely outside human control, which strikes quickly with little or no warning. It causes serious disruptions in life and property causing death and injury and therefore requires mobilization of efforts in excess of something which is normally provided by statutory emergency services. Two types of disasters are-natural disasters and man-made disasters.
Question 22.
Explain the food chain. [5]
Answer:
The sequence of eating and being eaten and the resultant transfer of energy from one level to another is known as the food chain. Transfer of energy that occurs during the process of a food chain from one level to another is known as the flow of energy. However, food chains are not isolated from one another. For example, a mouse feeding on grain may be eaten by different secondary consumers (carnivores) and these carnivores may be eaten by other different tertiary consumers (top carnivores).
In such situations, each of the carnivores may consume more than one type of prey. As a result, the food chains get interlocked with one another. This interconnecting network of species is known as a food web. For example, a plant-eating beetle feeding on a paddy stalk is eaten by a frog, which is, in turn, eaten by a snake, which is then consumed by a hawk.
(1) Producers: The producers include all the green plants, which manufacture their own food through photosynthesis.
(2) Primary consumers: The primary consumers include herbivorous animals like deer, goats, mice, and all plant-eating animals.
(3) Carnivores: The carnivores include all flesh-eating animals like snakes, tigers, and lions. Certain carnivores that feed also on carnivores are known as top carnivores like hawks and mongooses.
(5) Decomposers: Decomposers are those that feed on dead organisms (for example, scavengers like vultures and crows), and further break down the dead matter by other decomposing agents like bacteria and various microorganisms.
There are two -types of food chains:
- Grazing food chain: In a grazing food chain, the first level starts with plants as producers and ends with carnivores as consumers at the last level, with the herbivores being at the intermediate level. There is a loss of energy at each level, which may be through respiration, excretion, or decomposition. The levels involved in a food chain range between three to five and energy is lost at each level.
- Detritus food chain: A detritus food chain is based on autotrophs energy capture initiated by grazing animals and involves the decomposition or breaking down of organic wastes and dead matter derived from the grazing food chain.
Question 23.
Write a detailed note on Kashmir or North-Western Himalayas. [5]
Answer:
Kashmir or the North-Western Himalayas:
(1) It comprises a series of ranges such as the Karakoram, Ladakh, Zaskar, and Pir Panjal. The Northeastern part of the Kashmir Himalayas is a cold desert, which lies between the Greater Himalayas and the Karakoram ranges.
(2) Important glaciers of South Asia such as the Baltoro and Siachen are also found in this region. The Kashmir Himalayas are also famous for Karewa formations, which are useful for the cultivation of Zafran, a local variety of saffron.
(3) Some of the important passes of the region are Zoji La on the Great Himalayas, Banihal on the Pir Panjal, Photo La on the Zaskar, and Khardung La on the Ladakh range. Some of the important fresh-water lakes such as Dal and Wular and salt-water lakes such as Pangong Tso and Tso Moriri are also in this region.
(4) Kashmir and the North-Western Himalayas are well-known for their scenic beauty and picturesque landscape. The landscape of Himalayas is a major source of attraction for adventure tourists. Srinagar, the capital city of the state of Jammu and Kashmir, is located on the banks of the Jhelum river. Dal Lake in Srinagar presents an interesting physical feature. Jhelum in the valley of Kashmir is still in its youth stage and yet forms a meander- a typical feature associated with the mature stage in the evolution of fluvial landforms.
(5) The Southernmost part of this region consists of longitudinal valleys known as ‘duns’. Dehradun, Jammu dun, and Pathankot dun are important examples.
Question 24.
What kinds of steps have been taken by the Central Soil Conservation Board, set up by the Government of India? [5]
Answer:
The Central Soil Conservation Board, set up by the Government of India, has prepared a number of plans for soil conservation in different parts of the country. These plans are based on the climatic conditions, the configuration of the land, and the social behavior of people. Even these plans are fragmental in nature. Integrated land use planning, therefore, seems to be the best technique for proper soil conservation. Lands should be classified according to their capability; land use maps should be prepared and lands should be put to the right uses. The final responsibility for achieving the conservation of arid will rest on the people who operate on it and receive the benefits.
Question 25.
Explain the features of the black soil. [5]
Answer:
Features of black soil:
(1) Black soil covers most of the Deccan Plateau, which includes parts of Maharashtra, Madhya Pradesh, Gujarat, Andhra Pradesh, and some parts of Tamil Nadu.
(2) These soils are also known as the ‘Regur Soil’ or the ‘Black Cotton Soil’. The black soils are generally clayey, deep, and impermeable.
(3) They swell and become sticky when wet and shrink when dried. Therefore, during the dry season, these soils develop wide cracks. Thus, there occurs a kind of ‘self-plowing’.
(4) Because of this 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 rainfed ones, to sustain even during the dry season.
(5) Chemically, the black soils are rich in lime, iron, magnesia, and alumina. They also contain potash. However, they lack phosphorous, nitrogen, and organic matter. The color of the soil ranges from deep black to grey.
Question 26.
What are earthquakes? What are the socio-environmental consequences of earthquakes? [5]
Answer:
The Earthquakes result from a series of Earth movements brought about by a sudden release of energy during the tectonic activities in the Earth’s crust.
Socio-environmental consequences of the Earthquake:
(1) The idea of an Earthquake is often associated with fear and horror due to the scale, magnitude, and suddenness at which it spreads the disasters on the surface of the Earth without discrimination. It becomes a calamity when it strikes areas with a high density of population. It not only damages and destroys the settlements, infrastructure, transport and communication network, industries, and other developmental activities, but also robs the population of the material and socio-cultural gains that they have preserved over generations.
(2) It renders them homeless, which puts extra pressure and stress, particularly on the weak economy of developing countries.
(3) Earthquakes also have some serious and far-reaching environmental consequences. Surface seismic waves produce fissures on the upper layers of the Earth’s crust through which water and other volatile materials gush out, inundating the neighboring areas.
(4) Earthquakes are also responsible for landslides and often cause obstructions in the flow of rivers and channels resulting in the formation of reservoirs. Sometimes, rivers also change their course causing floods and other calamities in the affected areas.
