Hence, these lines are called parallels Pole, and the Antarctic Circle and South pole are of latitude. The latitudes are also called as called Frigid Zones. These zones are very cold temperature coordinates because with the as the sun does not rise above the horizon. increase in latitudinal distance towards the poles, the temperature reduces. Longitude It is an angular distance measured in degrees along the equator east or west of the Prime Meridian (0°). It varies from 0 to 180° E and 0 to 180° W. It is also called as time coordinates. Longitudes are also known as Great circles because it divides earth into two equal parts. Each longitude cuts each latitude at 90°. 1° = 4 minute i.e. 15° = 1 hour Meridians are a series of semicircles that run from pole to pole passing through the equator. N.P. W 0° °E 9 90 °E °W The most important lines of latitude are the 75 75 PRIME MERIDIAN Equator (0°), the Tropic of Cancer (23½°N), the Tropic of Capricorn (23½°S), the Arctic Circle W E 60° 60° (66½°N) and the Antarctic Circle (66½°S). The midday sun is exactly overhead at least 45°W 45°E once a year on all latitudes in between the Tropic 30°W 30°E of Cancer and the Tropic of Capricorn. This area, 15°W 15°E therefore receives the maximum heat and is 0° called the Torrid Zone (or Tropical Zone). 64 General Studies The Prime Meridian is at 0° and is known as the is called Revolution of earth (also called annual Greenwich line as it passes through Greenwich movement). near London, where the British Royal Observatory is located.

It is not Structure of Earth static but has two types of motions: (a) Rotational Motion (b) Revolutional (or Orbital) Motion (a) Rotation of Earth The earth spins (or rotates) continuously on its own axis from west to east once in every 24 hours, causing day and night. This motion is called Rotation of the Earth (also called ‘Daily Motion’). Day and Night: When the earth rotates on its own axis, only one portion of the earth’s surface comes into the rays of the sun and experiences day light whereas the other portion experiences darkness (or night). (b) Revolution of Earth The earth also revolves around the sun in an orbit The earth as a whole has been divided into three once in about 365 days and 6 hours, causing broad zones: formation of seasons and the year. This motion Geography 65 1. Crust (SIAL) : The earth is made up of several More than 75% of the total land area of the globe distinct layers but the outermost layer is called is situated to the north of the equator, therefore the the crust. The crust is not a continuous layer of northern hemisphere is also known as the ‘Land rocks, but consists of large masses called plates, Hemisphere’ and the Southern hemisphere as which are free to drift slowly over a layer called the ‘Water Hemisphere’. It is believed that the Asthenosphere. continents are moving away from each other, The crust has a thickness of about 33 km in the Several theories have been propounded to continents (Continental crust) and 5-10 km thick explain this phenomenon: in the ocean basins (Oceanic crust). Silica and Continental Drift Theory: Aluminium are the main constituent of the earth This theory was proposed by famous German therefore it is also known as Sial. Geographer, Prof. Alfred Wagner in 1924. 2. Mantle (SIMA) : The layer of rock below the crust According to this theory, before 200 million years is called the mantle. It is about 2900 km thick and ago, there was a single land mass surrounded by is divided into the upper and lower mantle. This water which was named as Pangea. layer contains most of the mass of the earth, and is where most of the earth’s heat is located. The mantle is composed mainly of Ferro-magnesium silicates. (a) Upper Mantle: The upper mantle is about 650 km thick and has two distinct layers. The top layer of the upper mantle is solid. Combined with the crust, this layer forms the Lithosphere, which makes up the earth’s plates. With in this layer is the Asthenosphere, where semi molten rock flows slowly. (b) Lower Mantle : The lower mantle is solid and About 200 million years ago, pangea got cracked is about 2700 km thick. Though temperatures into two parts i.e. (a) Angaraland (or Laurasia) are higher here but the tremendous pressures (b) Gondwana land, and ocean water filled in it. keep the rock material from melting. As a result, a narrow sea was created, known as 3. Core : It is the innermost part of the earth and it Tethy’s Sea. comprises of outer core and inner core. (a) Outer Core : The outer core is liquid and is about 1900 km thick. It comprises of molten iron and nickel, formed as a result of the extremely high temperature. This liquid outer core controls the earth’s magnetic field. (b) Inner Core: The earth’s innermost core is about 1600 km thick and is made up of solid iron and nickel. The inner core is incredibly hot, with temperature reaching about 5,500°C and is subjected to a pressure of about 4 million atmospheres. It is this extreme pressure During further course of time, Angaraland was that keeps the inner core in a solid state. cracked into: (i) North American Plate (ii) Eurasian Plate Formation of Continents Whereas Gondwana land was cracked into 5 plates: The age of earth is about 4500 million years (i) African Plate (4.5 billion) and about 70%, of the total surface (ii) South American Plate area of the globe is represented by the oceans (iii) Indian Plate (Hydrosphere), whereas remaining, 29.2% is (iv) Australian Plate represented by the continents, (Lithosphere).

It flourished around the The period of the prehistoric agriculturalists and Indus river and its tributaries. The area consists pastoralists was during approximately the 8th to of modern Pakistan and Northwestern India. the mid-fourth millennium BCE. Mohenjodaro is the largest site of the Civilization. Indus valley civilization is also called as Harappan civilization because Harappa was the first site to be excavated in 1921 under the supervision of Daya Ram Sahni. The known extent of this civilization in the west is upto Sutkagendor in Baluchistan; Alamgirpur (UP) in the east; Daimabad (Maharashtra) in South; and Manda (J and K) in the north.

Important Features of Indus Valley Civilization Town planning was the most distinguishable feature of the Harappan civilization. Hence, this civilization is also called first urbanisation. Towns were divided into parts viz. citadel and lower town. Citadels were occupied by members of ruling class and lower town was inhabited by the common people. Harappan cities were developed in Block Pattern/Chess Board Pattern because roads of these cities used to cut each other at right angles. Most peculiar feature of town planning was their drainage system. Drains were built of burnt bricks and covered by stone lids and manholes for cleaning. Complete burial was the most common method of the disposal of the dead. They grew wheat and barley on a large scale. The other crops grown were pulses, cereals, cotton, dates, melons, pea, sesamum and mustard. No clear evidence of rice has been found, except from Rangpur and Lothal where some grains of rice were found, but they may be of later period. Harappan people were mostly peasants and thus the Harappan civilization was an agro-commercial civilization. Evidences of hoe and plough have been found in kalibangan and Banawali.

Phylum Porifera (Pore Bearing Animals) When any plane passing through the central axis These are commonly known as sponges. They of the body divides the organism in two halves are the most primitive group of multicellular that are approximately mirror images it is called animals. About 5000 species of sponges are Radial symmetry and the animals showing radial symmetry are called Radiata. known. Most of them are marine and remain When the body can be divided into identical left attached to rocks. A few live in fresh water. and right halves in only one plane. This kind of The sponges are diploblastic. symmetry is called bilateral symmetry and such Sponges reproduce asexually by animals are called Bilateria. fragmentation. Almost 99 percent of animals are invertebrates 3. Phylum Cnidaria (animals without backbone) and the remaining The phylum name is derived from the stinging represents the vertebrates (animals with cells or cnidoblasts present on the ectoderm backbone). Also, the animals are categorised into of tentacles and body of the carnivorous two major groups, non-chordates and chordates, animals. Cnidarians have achieved tissue on the basis of the presence or absence of grade of organisation and they exhibit a blind notochord at some stage in their life. sac body plan and radial symmetry. The animal kingdom is divided into 35 Phyla (singular: Cnidarians are diplosblastic animals in which Phylum) of which 11 are considered as major Phyla. the body wall consists of only two layers 1. Phylum Protozoa (Unicellular Protist Animals) or cells, an outer ectoderm and an inner They are microscopic organisms in which a endoderm, separated by a gelatinous layer of single cell performs all the vital activities. mesoglea. They are aquatic (fresh water and marine) and Examples: Hydra, Obelia, Porpita, Vellela, cosmopolitan in distribution. Some forms are Physalia (Portuguese man of war), Aurelia parasitic. The protozoan cell body is either (Jellyfish), Adamsia (Sea anemone), Pennatula naked, (for example, amoeba) or surrounded (Sea-pen) and Gorgonia (Sea-fan). by a non-rigid pellicle (Cellulose is absent in 4.

Most protozoans are free-living and aquatic. The presence of a special sense organ at the They are holozoic and feed largely on opposite end of the mouth (aboral end) is the bacteria, microscopic algae and minute characteristic of the members of this phylum. animals such as rotifers or on other protozoans They reproduce only by sexual means and do including members of their own species. Some not exhibit larval phase in their life cycle. protozoans are holophytic i.e. they prepare their own food by photosynthesis (e.g. Euglena). 5. Phylum Platyhelminthes (Flatworms) These are dorsoventrally flattened and, hence, General Science Biology 383 commonly known as flatworms. These are Examples: Araneus (garden spider), Limulus mostly parasites. (king crab), Buthus (scorpion), Eupagurus These are triploblastic and unsegmented (hermit crab), Cancer (common crab), animals exhibiting bilateral symmetry. Macrobrachium (prawn), Lepisma (silverfish), They reproduce both asexually and sexually. Periplaneta (cockroach), Apis (bee), Anopheles They are hermaphrodites or bisexual i.e., both (mosquito), Musca (housefly), Leptocorisa male and female sex cells are produced by the (paddy pest: gandhi poka), Triops (tadpole fish), same individual. Daphnia (water flea), Cyclops, Squilla, Astacus Examples: Taenia (Tapeworm), Fasciola (Liver (crayfish), Lepas and Balanus (Barnacle). Fluke), Schistosoma (Blood fluke) etc. 10. Phylum Chordata (Scordates) 6. Phylum Nemathelminthes (Round Worms) Chordata refers to the group of animals which These are also known as nematodes. Their possess notochord either throughout or during bodies appear circular in cross-section, early embryonic life. Notochord is a stiff and hence, the name roundworm. Though not flexible rod of tissues lying ventral to nerve apparent they are possibly the most abundant chord. All the chordates are triploblastic, and numerous among animals. coelomate and bilaterally symmetrical. Roundworms are bilaterally symmetrical, Phylum Chordata is divided into four triplo-blastic and pseudocoelomate animals subphyla viz. subphylum Hemichordata or with an organ system grade of organization. stomochordata, subphylum Urochordata or Round worms have a tube within a tube body Tunicata, subphylum Cephalochordata or plan with mouth, faringes, intestine and anus. Acrania and subphylum Vertebrata. Sexes are usually separate, often with small male and large female individuals. Difference between Chordates & Examples: Ascaris, Wuchereria (Filaria Non-chordates worm), Ancylostoma (Hook worm), Enterobius Chordates Non-Chordates (Pin worm) and Rhaditis. 7. Phylum Annelida 1.

Phylum Echinodermata (Spiny Skinned Animals) Octopus (devilfish), Doris (sea-lemon), Aplysia Echinoderms bears many spines and hence (sea-hare) and Teredo (shipworm). all are marine, triploblastic and coelomate. 9. Phylum Arthropoda The most distinctive feature of echinoderms is the presence of water vascular system, which The phylum Arthropoda constitutes the largest group of animals with about 900,000 is a part of the coelom. Its main function is species. These are triploblastic, coelomate locomotion and capture of food. and bilaterally symmetrical animals. Examples: Asterias (star fish or sea Arthropods have a segmented body, each star), Echinus (sea urchin), Echinocardium segment bearing a pair of jointed appendages (heart urchin), Antedon (feature star of sea covered by a jointed exoskeleton. lily), Cucumaria (sea cucumber) and Ophitura Arthropods are unisexual.
