Q18. Read the given Passage carefully and answer the questions that follow: 3
Physical geography includes the study of the lithosphere (landforms, drainage, relief and physiography), atmosphere (its composition, structure, elements and controls of weather and climate; temperature, pressure, winds, precipitation, climatic types, etc.), hydrosphere (oceans, seas, lakes and associated features with water realm) and biosphere (life forms including human beings and macro-organisms and their sustaining mechanism, viz. food chain, ecological parameters and ecological balance). Soils are formed through the process of pedogenesis and depend upon the parent rocks, climate, biological activity, and time. Time provides maturity to soils and helps in the development of soil profiles. Each element is important for human beings. Landforms provide the base on which human activities are located. The plains are utilized for agriculture.
Plateaus provide forests and minerals. Mountains provide pastures, forests, and tourist spots and are sources of rivers providing water to lowlands. Climate influences our house types, clothing, and food habits. The climate has a profound effect on vegetation, cropping patterns, livestock farming some industries, etc. Human beings have developed technologies that modify climatic elements in a restricted space such as air conditioners and coolers. Temperature and precipitation ensure the density of forests and the quality of grasslands. In India, monsoonal rainfall sets the agriculture rhythm in motion. Precipitation recharges the groundwater aquifers, which later provide water for agriculture and domestic use.

Question numbers 20 to 23 are Short Answer Type Questions.
Q20. What do you know about montane forests? 3
OR
Mention the characteristics of monsoonal rainfall in India.
Ans: In mountainous areas, the decrease in temperature with increasing altitude leads to a corresponding change in natural vegetation. Mountain forests can be classified into two types, the northern mountain forests and the southern mountain forests.
The Himalayan ranges show a succession of vegetation from the tropical to the tundra, which changes with altitude. Deciduous forests are found in the foothills of the Himalayas. It is succeeded by the wet temperate type of forests between an altitude of 1,000 – 2,000 m. Between 1,500 – 1,750 m, pine forests are also well-developed in this zone, with Chir Pine as a very useful commercial tree. Deodar, a highly valued endemic species grows mainly in the western part of the Himalayan range. Deodar is a durable wood mainly used in construction activities. Blue pine and spruce appear at altitudes of 2,225 – 3,048 m. But in the higher reaches, there is a transition to Alpine forests and pastures. Silver firs, junipers, pines, birch and rhododendrons, etc., occur between 3,000 – 4,000 m.
The southern mountain forests include the forests found in three distinct areas of Peninsular India viz; the Western Ghats, the Vindhyas and the Nilgiris. As they are closer to the tropics and only 1,500 m above the sea level, vegetation is temperate in the higher regions and subtropical on the lower regions of the Western Ghats, especially in Kerala, Tamil Nadu and Karnataka.
OR
The characteristics of monsoonal rainfall in India are:
(i) Rainfall received from the South-West monsoons is seasonal in nature, and occurs between June and September. The monsoon rainfall has a declining trend with increasing distance from the sea. For example, Kolkata receives 119cm of rain during the south-west monsoon whereas, Allahabad receives 76 cm.
(ii) The summer rainfall comes in a heavy downpour leading to considerable runoff and soil erosion. Monsoon also plays a pivotal role in the agrarian economy of India because over three-fourths of the total rain in the country is received during the South-west monsoon season.
(iii) The spatial distribution of monsoons across the country is uneven. It ranges from 12cm to more than 250 cm. The beginning of the rains sometimes is considerably delayed over the whole or a part of the country.
Q21. Explain the depositional landforms made by the winds. 3
Ans: The various depositional landforms made by wind are:
Q22. What are the primary forces that influence the currents? 3
OR
What are the characteristics of ocean currents?
Ans: The primary forces that influence the currents are:
OR
purrents are referred to by their ’drift’. Usually, the currents are strongest near the surface and may attain speeds over five knots. At depths, currents are generally slow with speeds less than 0.5 knots. We refer to the speed of a current as its ‘drift’. Drift is measured in terms of knots. The strength of a current refers to the speed of the current. A fast current is considered strong. A current is usually strongest at the surface and decreases in strength (speed) with depth. Most currents have speeds less than or equal to 5 knots.
Q23. What do you know about India’s neighbours? 3
Ans: Pakistan, Nepal, Bhutan, Bangladesh along with India form a part of the Indian subcontinent. India is located in the south-central part of the continent of Asia, bordering the Indian Ocean and its two arms extending in the form of the Bay of Bengal and the Arabian Sea.
This maritime location of Peninsular India has provided links to its neighbouring regions through the sea and air routes. Sri Lanka and Maldives are two island countries located in the Indian Ocean, which are our neighbours.
Sri Lanka is separated from India by the Gulf of Mannar and the Palk Strait. Besides India also shares its boundary with China.
Question numbers 24 to 28 are Long Answer Type Questions.
Q24. Explain tropical cyclones. 5
Ans: Tropical cyclones are violent storms that originate over oceans in tropical areas and move over to the coastal areas bringing about large-scale destruction caused by violent winds, very heavy rainfall and storm surges.
This is one of the most devastating natural calamities. They are known as Cyclones in the Indian Ocean, Hurricanes in the Atlantic, Typhoons in the Western Pacific and South China Sea, and Willy-willies in Western Australia. Tropical cyclones originate and intensify over warm tropical oceans. The conditions favourable for the formation and intensification of tropical storms are
The energy that intensifies the storm, comes from the condensation process in the towering cumulonimbus clouds, surrounding the centre of the storm. With a continuous supply of moisture from the sea, the storm is further strengthened. On reaching the land the moisture supply is cut off and the storm dissipates. The place where a tropical cyclone crosses the coast is called the landfall of the cyclone. The cyclones, which cross 20°N latitude generally, re-curve and they are more destructive.
A mature tropical cyclone is characterised by the strong spirally circulating wind around the centre, called the eye. The diameter of the circulating system can vary between 150 and 250 km. The cyclone creates storm surges and they inundate the coastal lowlands. The storm peters out on the land.
Q25. Explain the essential features of the South West Monsoon Season. 5
Ans: Important features of the South West Monsoon Season:
(i) The southeast trade winds cross the equator and enter the Bay of Bengal and the Arabian Sea, only to be caught up in the air circulation over India. Passing over the equatorial warm currents, they bring with them moisture in abundance. After crossing the equator, they follow a south-westerly direction. That is why they are known as southwest monsoons.
(ii) The rain in the southwest monsoon season begins rather abruptly. One result of the first rain is that it brings down the temperature substantially.
(iii) This sudden onset of the moisture-laden winds associated with violent thunder and lightning, is often termed as the ‘break’ or ‘burst’ of the monsoon. The monsoon may burst in the first week of June in the coastal areas of Kerala, Karnataka, Goa and Maharashtra, while in the interior parts of the country, it may be delayed to the first week of July. The day temperature registers a decline of 5°C to 8°C between mid-June and mid-July.
(iv) As these winds approach the land, their southwesterly direction is modified by the relief and thermal low pressure over northwest India. The monsoon approaches the landmass in two branches: (i) The Arabian Sea branch (ii) The Bay of Bengal branch.
(v) The monsoon winds originating from the Arabian Sea are further divided into three branches: Its one branch is obstructed by the Western Ghats. Another branch of the Arabian Sea monsoon strikes the coast north of Mumbai. A third branch of this monsoon wind strikes the Saurashtra Peninsula and the Kachchh. The Bay of Bengal branch strikes the coast of Myanmar and part of southeast Bangladesh.
Q26. Explain with the help of a diagram how does the shadow zone emerge? 5
OR
What are the effects of the earthquake?
Ans: (i) Earthquake waves get recorded in seismographs located at far off locations. However, there exist some specific areas where the waves are not reported. Such a zone is called the ‘shadow zone’. The study of different events reveals that for each earthquake, there exists an altogether different shadow zone.
(ii) Seismographs located at any distance within 105° from the epicentre, recorded the arrival of both P and S-waves. However, the seismographs located beyond 145° from epicentre, record the arrival of P-waves, but not that of S-waves. Thus, a zone between 105° and 145° from epicentre was identified as the shadow zone for both the types of waves. The entire zone beyond 105° does not receive S-waves.
(iii) The shadow zone of S-waves is much larger than that of the P-waves. The shadow zone of P-waves appears as a band around the earth between 105° and 145° away from the epicentre. The shadow zone of S-waves is not only larger in extent but it is also a little over 40 per cent of the earth’s surface.
OREarthquake is a natural hazard. The following are the immediate hazardous effects of earthquakes:
Q27. Physical divisions of India are alternative to each other.’ Justify. 5
OR
Differentiate western coastal plain and eastern coastal plain.
Ans: The physical divisions of India are alternative to each other because:
(i) Himalayas are the storehouse of water as they rise to Perennial rivers which provide ample water for irrigation. Himalayas are also a source of forest produce and serve as a climatic divide.
(ii) The Northern Plains have fertile soil which is suitable for agriculture and also provides raw
materials for industries. The Northern Plains are also known as the ‘Food Bowl of India’.
(iii) Peninsular India is the storehouse of minerals, which are of great use to industries and are exported across the world. The Ghats are responsible for generating hydroelectricity.
(iv) The coastal plains are important for ports, the arrival of monsoons, international trade, and fishing etc. The coastal plains are world famous for the spices which are exported worldwide.
(v) The deserts are known as tourist attractions. The lakes and the playas have brackish water which is the main source of obtaining salt. The island group is known for the corals, volcanoes and are a major tourist destination. Thus, no part of India can grow and develop in isolation. They all are interdependent and cannot grow without each other. One part needs the support and cooperation of the other.

Q28. How did the Peninsular Drainage System evolve? 5
OR
If you move from Badrinath to Sundarbans delta along the course of the river Ganga, what maj or geomorphological features will you come across?
Ans: Three major geological events in the distant past have shaped the present drainage systems of Peninsular India:
OR
If you move from Badrinath to Sunderbans delta along the course of the river Ganga, we come across the following major geomorphological features:
(i) V-shaped valleys: Valleys start as small narrow rills, the rills will gradually develop into long and wide gullies, and the gullies will further deepen, widen and lengthen to give rise to valleys. Depending upon dimensions and shape, many types of valleys like v-shaped valleys, gorges, canyons, etc., can be recognised.
(ii) Gorge: A gorge is a deep valley with very steep to straight sides.
(iii) Canyon: A canyon is characterised by steep step-like slopes and may be as deep as a gorge. A gorge is almost equal in width at its top as well as at its bottom. In contrast, a canyon is wider at its top than at its bottom. In fact, a canyon is a variant of a gorge.
(iv) Waterfall: When the rivers start falling in pits in mountainous regions, it makes a waterfall.
(v) Plunge pools: Once a small and shallow depression forms, pebbles and boulders get collected in those depressions and get rotated by flowing water and consequently the depressions grow in dimensions. A series of such depressions eventually join and the stream valley gets deepened. At the foot of waterfalls also, large potholes, quite deep and wide, form because of the sheer impact of water and rotation of boulders. Such large and deep holes at the base of waterfalls are called plunge pools.
