INDIAN GEOPGRAPHY Q: In a particular region in India, the local people train the roots of living tree into robust bridges across the streams. As the time passes these bridges become stronger. These unique 'Living Root Bridges are found in a) Meghalaya b) Himachal Pradesh c) Jharkhand d) Tamil Nadu
Solution: a) cker root bridges are unique in the world Meghalaya's double-decker and single-de and are a sight to behold. The bridges are tangles of massive thick roots, which have been intermingled to form a bridge that can hold several people at a time. Khas people have been trained to grow these bridges across the raised banks of streams to form a solid bridge, made from roots. The living bridges are made from the roots of the Ficus elastic tree, which produces a series of secondary roots that are perched atop s or the riverbanks to form bridges. huge boulders along the stream The root bridges, some of which are over a hundred feet long, take ten to fifteen years to become fully functional, but they're extraordinarily strong - strong enough that some of them can support the weight of fifty or more people at a time. The bridges are alive and still growing and gain strength over time
Q: Consider the following States: 1. Arunachal Pradesh 2. Himachal Pradesh 3. Mizoram In which of the following states do "Tropical Wet Evergreen Forests" occur? a) 1 only b) 2 and 3 only c) 1 and 3 only d) 1, 2 and 3
Solution: c) These are typical rain forests which grow in those areas where the annual rainfall exceeds 250 cm, the annual temperature is about 25 -27 C the average annual humidity exceeds 77 per cent and the dry season is distinctly short. The true evergreen forests are found along the western side of the Western Ghats (between 500 to 1370 metres above sea level) south of Mumbai, in a strip running from northeast to south-west direction across Arunachal Pradesh, Upper Assam, Nagaland, Manipur, Mizoram and Tripura upto a height of 1070 metres and in the Andaman and Nicobar Islands.

Q: In India, in which one of the following types of forests is teak a dominant tree species? a) Tropical moist deciduous forest b) Tropical rain forest c) Tropical thorn scrub forest d) Temperate forest with grasslands
Solution: a) orests exist mostly in the eastern part of the country Tropical moist deciduous f northeastern states, along the foothills of the Himalayas, Jharkhand, West Orissa and Chhattisgarh, and on the eastern slopes of the Western Ghats. Teak is the most dominant species of this forest. Bamboos, sal, shisham sandalwood, khair, kusum, arjun, mulberry are other commercially important species.

Solution: d) The South Andaman forests have a profuse growth of epiphytic vegetation, mostly ferns and orchids. The Middle Andamans harbours mostly moist deciduous forests. North Andamans is characterized by the wet evergreen type, with plenty of woody climbers. The North Nicobar Islands (including Car Nicobar and Battimalv) are marked by the complete absence of evergreen forests, while such forests form the dominant vegetation in the central and southern islands of the Nicobar group Grasslands occur only in the Nicobars, and while deciduous forests are common in the Andamans, they are almost absent in the Nicobars. The present forest coverage is claimed to be 86.2% of the total land area.
Q: Which one of the following countries of South-West Asia does not open out to the Mediterranean Sea? a) Syria b) Jordan c) Lebanon d) Israel

Q: "Each day is more or less the same, the morning is clear and bright with a sea breeze; as the sun climbs high in the sky, heat mounts up, dark clouds form, than rain comes with thunder and lightning. But rain is soon over." Which of the following regions is described in the above passage? a) Savannah b) Equatorial c) Monsoon d) Mediterranean
Q: In the South Atlantic and South Eastern Pacific regions in tropical latitudes, cyclone does not originate. What is the reason? a) Sea Surface temperature are low b) Inter Tropical Convergence Zone seldom occurs c) Coriolis force is too weak d) Absence of land in those regions
Solution: a) Option C is wrong. Coriolis force is weak only in the region around 0-5 degrees North or South latitudes Option B is also wrong. ITCZ formation is not essential to the formation of cyclones Cyclones are formed in regions where ITCZ does not form, for e.g. in North Atlantic. Option D is absurd as absence of land boosts cyclones. Presence of land cuts off moisture from the cyclone. So, the most appropriate answer should be A For cyclone formation, a sea temperature of at least 26 degree Celsius is needed. In the South-eastern pacific and South Atlantic region cold currents are found. Thi:s leads to lower sea temperatures. Hence, cyclones don't form there
Solution: c) Statement 1 is absurd. Increasing the amount of nitrogen based fertilizer does not lead to more miero-organisms in the field. If it did, just one dose of fertilizer would make a farm gether. nitrogen rich for years to Statement 2: Excessive use of nitrogen fertilizers resulting in soil acidity is a well-known fact. Statement 3: Nitorgen fertilizers break down into nitrates and travel easily through the soil. Because it is water-soluble and can remain in groundwat addition of more nitrogen over the years has an accumulative effect. er for decades, the
Solution: b) The equatorial countercurrents are driven by a distinct surface wind pattern in the tropics. Strong westward trade winds result in westward surface flow in most of the tropical Atlantic and Pacific Oceans. However, several hundred mi. (km.) north of the equator the winds are much weaker, in comparison. The stronger winds to the south pile up water where the winds are weak. As a result, the surface of the ocean can be up to 6 in. (15 cm.) higher and the thermocline (region of strongest decrease of temperature with increasing depth) as much as 328 ft. (100 m.) deeper than it is directlv to the north. The excess water flows eastward under the influence of the Earth's rotation, giving rise to the equatorial countercurrents.
