An adjunct of Delhi, Daryana practically remained anonymous until the First War of India’s independence in 1857. After the British crushed the rebellion, they deprived the Nawabs of Jhajjar and Bahadurgarh, the Raja of Ballabgarh and Rao Tula Ram of Rewari in Haryana region, of their territories. These were either merged with British territories or handed over to the rulers of Patiala, Nabha and Jind, making Haryana a part of the Punjab province. With the reorganization of Punjab on 1 November 1956. Haryana was born as a fullfledged state. Strategically located, Haryana is bounded by Uttar Pradesh I the east, Punjab in the west, Himachal Pradesh in the North, and Rajasthan in the south. The National Capital of Delhi juts into Haryana. With just 1.37 per cent of the total geographical area and less than two percent of India’s population, Haryana has carved a place of distinction for itself. Whether it is agriculture or industry, canal irrigation or rural electrification, Haryana keeps marching towards modernity. The state enjoys the unique distinction of being among the first to provide electricity, metalled roads and portable drinking water to all its villagers. Ranked among the most prosperous states in India, Haryana has the second highest per capita income in the country, after Goa.

ANDHRA PRADESH

Area : 2,75,069 sq km
Population : 8.32 crores as on 1.3.09
Capital : Hyderabad Principal
Languages : Telugu and Urdu

HISTORY AND GEOGRAPHY

The earliest mention of the Andhras is said to be Aitereya Brahmana (2000BC). It indicates that the Andhras, originally an Aryan race living in north India migrated to south of the Vindhyas and later mixed with non-Aryans. Regular history of Andhra Desa, according to historians, begins with 236 BC, the year of Ashoka’s death. During the following centuries, Satavahanas, Sakas, Ikshvakus, Eastern Chalukyas, and Kakatiyas ruled the Telugu country. Other dynasties that ruled over the area in succession were the kingdoms of Vijayanagar and Qutub Shahi followed by Mir Qumruddin and his successors, known as the Nizams. Gradually, from the 17th century onwards, the British annexed territories of the Nizam and constituted the single province of Madras. After Independence, Telugu-speaking areas were separated from the composite Madras Presidency and a new Andhra State came into being on 1 October 1953. with the passing of the States Reorganisation Act, 1956, there was a merger of Hyderabad State and Andhra State, and consequently Andhra Pradesh came into being on 1 November 1956.

    THE PURVANCHAL

    (The North Eastern Highland)

    • The Himalaya range after crossing the Dihang gorge in the east, bends southwards, forming a series of hills in north south trend.
    • They are divided into six physiographic region-Purvu-NEFA (Mishmi hills, Patkai Bum), Nagaland, the Manipur Hills, North Cachar Hills, Mizo Hills and the Tripura Hills.

    PURVU NEPA

    (i) Mishmi Hills

    Physiographic Regions

    Atmosphere (Part -1)

    • Our planet is enveloped by a keep blanket of gases extending several kilometers above its surface.
    • Like the lithosphere and hydrosphere, the atmosphere too is an integral part of a gigantic system i.e. earth.
    • When compared with the radius of our planet, the atmosphere appears to be only a very thin layer of gases.
    • However, because of the force of gravity, it is inseparable from the Earth.

    (IGP) IAS Pre: GS - Geography - World Geography Physical: Atmosphere (Part -2)

    Atmosphere (Part -2)

    • Rains in the doldrums are of convectional nature and are also called the 4 O’ clock showers.

    B. Orographic Precipitation

    • It occurs when warm and humid air strikes landform barriers such as mountain ranges and is forced to rise.
    • The windward side of the mountain range gets more precipitation than the leeward side (rainshadow area) because the air descends down the slope and gets warmed up.

    (IGP) IAS Pre: GS - Geography - World Geography Physical: Lithosphere (Part -2)

    World Geography Physical
    Lithosphere (Part -2)

    Continental Plateaus

    • They rise abruptly from the lowlands or from the sea.
    • They are the result of a continental uplift producing large tablelands like the plateaus of Brazil, South Africa, West Australia, Chotanagpur and Shillong. Their heights vary from 600-1,500 metres.
    • Sometimes a plain or a low-lying area is vertically uplifted and gives rise to a plateau.
    • In India, plateaus of Kaimur, Rohtas, Ranchi and Karnataka are of this type.
    • The Potwar plateau of Pakistan also falls in this category.

    Our Planet Earth

    • Earth, the home to mzankind, is a unique member of the solar family.
    • The fifth biggest planet in the solar system, its uniqueness lies in its habitabilitzz vertically overhead at the equator on two days each year, i.e. on March 21st and September 23rd. These days are called equinoxes meaning ‘equal nights’ because on these two days all places on Earth have equal days and nights.

    • After the March equinox, the sun appears to move northwards and is vertically overhead at the Tropic of Cancer on June 21st. Thus is known as the summer solstice, when the northern hemisphere will have its longest day and shortest night.

    • By December 22nd, the sun is overhead at the Tropic of Capricorn. This is the winter solstice when the southern hemisphere will have its longest day and shortest night.

    OCEAN CURRENTS

    The general movement of large mass of surface water in definite pattern is called ocean currents.

    CAUSES OF THE MOVEMENT OF OCEAN CURRENTS

    1. The earth’s rotation which results in the genesis of deflective or coriolis force.
    2. The planetary winds.
    3. Difference in the temperature of ocean waters between the equator and the poles.
    4. Similarly of ocean affects the density of water, which is the main cause of movement of ocean water.
    5. Shape and configuration of the continent determines the direction of ocean current.
