Archaean or Pre-Cambrian (2500 million years ago)
आर्कसयन या प्री-कैम्ब्रियन युग
• The Archaean or Pre-Cambrian era is the oldest era in Earth's history. This is the division of
geologic time scale from the formation of the Earth (about 4.6 billion years ago) to the beginning of the
Cambrian Period of the Paleozoic Era (about 570 million years ago). 86.7% of the time of Earth's history
is considered pre-Cambrian era. Archaean terminology was first used in 1782 by J. D. Dana.
• Fossil-free rocks, abundance of crystals, heavy debris and deformed turns are found.
• आर्कियन या प्री-कैम्ब्म्ियन युग पथ् ृ िी के इनतहास का स से पुराना युग है । यह भूगलभिक समय के पैमाने का
विभाजन है जो पथ्ृ िी के गठन (िगभग 4.6 ब लियन िर्ि पि ू )ि से िेकर पैलियोजोइक यग

माना जाता है । 1782 में जे. डी. डाना ने स से पहिे आर्कियन शब्दाििी का प्रयोग र्कया था।
• जीिाश्म मुक्त चट्टानें, र्क्रस्टि की प्रचुरता, भारी मि ा और विकृत मोड़ पाए जाते हैं।

there was no origin of species during their formation. The
Cuddapah formations, named after the district of Cuddapah
in Andhra Pradesh, are sedimentary-metamorphic
formations.

The Cretaceous System (The Deccan Trap) र्क्रटे मियस प्रणाली (दक्कन ट्रै प)
• Towards the end of the Cretaceous period the Peninsula was affected by intense volcanic activity.
During this period, enormous quantity of basaltic lava was poured out to the surface assuming a great
thickness of over three thousand metres. The Lava Plateau (the Deccan Trap) is the result of that lava
eruption.
• The Deccan lava covers about five lakh sq km of area in Gujarat (Kachchh, Kathiawad), Maharashtra,
Madhya Pradesh (Malwa Plateau), Chhattisgarh, Jharkhand, northern Andhra Pradesh and north-
western Karnataka.

The Northern Plains

• The northern plain as a physiographic feature in India is the youngest amongst others. The northern
plains account for less than one-third of the country's total area while supporting around 40% of the
entire population of the country. They are located south of the Shiwaliks. The southern boundaries of
the northern plains are wavy and irregular boundaries along the northern edge of Peninsular India. To the
eastern side, they are flanked by the Purvanchal hills. To the western side, they are flanked by the Punjab
plains and the Aravali hills.

• Features of the Northern Plains
• Three major river systems of India, i.e., the Ganga,the Brahmaputra, and the Indus with their
tributaries, formed the Northern Plains of India.
• The northern plains of India form the largest alluvial tract in the world.
• They extend in an east-west direction of approximately 3200 kilometers, while the average width
varies between 150 and 300 kilometers. The width of the plains increases from east to west.

• Bhabar:
• The rivers that originate from the Himalayas, deposit the sediment loads along the foothills, thus,
forming alluvial fans. These alluvial fans consist of coarser sediments that merge to form the Bhabar or
the Piedmont plain. Bhabar is a narrow and porous belt of coarser sediments that runs (8 to 10 km) east-
west direction along the foothills of the Himalayas.
• The track is unsuitable for agriculture; however, trees with deep penetrating roots survive in this
region.

Hills and north of the Indo-Gangetic Plain. They are located south of Bhabar and run parallel to it with
an approximate width of 10 to 20 kilometers.
• Characteristic features:
• This region is characterized by marshy lands.
• The soils here are rich in organic matter and nitrogen but are deficient in phosphate.
• The heavy rainfall in the eastern region of India, rises the water table and leads to broader Terai in the
Brahmaputra valley lying east of the Great Plains.
• Tarai region is distinguished by a luxurious growth of natural vegetation and varied wildlife. Some of
the major national parks are located in this region.

• Bhangar:
• Bhangar is the old alluvium deposits along the river beds that are in the shape of terraces higher than the
floodplain.
• Characteristic features:
• They are productive, rich in humus, and dark in colour. The composition of soil is mostly clayey and
has lime distributed called kankar. They are mostly seen doabs (the land between two rivers).
• In some areas, the Bhangar showcases small tracts of alkaline and saline powder minerals and salts that
rise on the surface due to capillary action and is known as "Reh", "Kallar" or "Bhur".

• Significance of The Great Plains of India
• The soils of the plains are agriculturally most fertile. They are being devoted to the cereal and non-
cereal crops. The plains are often termed as the “Granary of India”.
• Most of the rivers traversing the Northern Plains of India are perennial in nature (agriculture).
• The northern plains have a rich underground water-table which is being utilised through tube-wells
and pumping sets for irrigation, domestic and industrial purposes.
• The rivers of the plain have very gentle gradients which makes them navigable over long distances.
• Development of infrastructure like roads and railways could become easy in the plains.
• The sedimentary rocks of plains have petroleum and natural gas deposits.
• The plains constitute less than one-third of the total area of the country, but support over 40% of the
total population of the country.

The Coastal Plains

• India has a coastline of 7516.6 km (6100 km of mainland coastline + coastline of 1197 Indian islands)
touching 9 States and 4 Union Territories (UTs). The straight and regular coastline of India is the result of
faulting of the Gondwana land during the Cretaceous period.
• As such the coast of India does not offer many sites for good natural harbours. Indented coastlines
of Europe provide good natural harbours whereas African and Indian coastlines are not indented.
• The Bay of Bengal and the Arabian Sea came into being during the Cretaceous or early Tertiary period
after the disintegration of Gondwanaland.

• भारत में 9 राज्यों और 4 केंद्र शालसत प्रदे शों (यूटी) को छूने िािी 7516.6 र्कमी (6100 र्कमी की मुख्य भूलम
