The Deccan Traps

How was Deccan Plateau formed?

It was formed by volcanic activity that lasted millions of years, causing the deposition of lava. After the volcanoes became extinct, the layers of lava transformed into a region of highland known as the Deccan plateau.

What are the Deccan Traps How were they formed?

The bulk of the volcanic eruption occurred at the Western Ghats between 65 and 66 million years ago when lava began to extrude through fissures in the crust known as fissure eruptions.

When was the Deccan Plateau formed?

Geology. The volcanic basalt beds of the Deccan were laid down in the massive Deccan Traps eruption, which occurred towards the end of the Cretaceous period between 67 and 66 million years ago.

Where does the Deccan plateau start?

Deccan, the entire southern peninsula of India south of the Narmada River, marked centrally by a high triangular tableland. The name derives from the Sanskrit daksina (“south”). The plateau is bounded on the east and west by the Ghats, escarpments that meet at the plateau’s southern tip.

How was the Indian plateau formed?

It was formed due to the breaking and drifting of the Gondwana land and thus, making it a part of the oldest landmass. The plateau has broad and shallow valleys and rounded hills. This plateau consists of two broad divisions, namely, the Central Highlands and the Deccan Plateau.

Which plateau is also known as Deccan Plateau?

The Deccan Plateau, also known as the Peninsular Plateau or the Great Peninsular Plateau, is a large plateau in India, making up the majority of the southern part of the country, ranging in elevation from 100 metres in the north to 1000 metres in the south.

How are Deccan Traps formed Upsc?

Deccan Trap is a thick sequence (3200 metres) of late cretaceous basaltic lava flows that cover about 500000 sq. km. of peninsular India. Due to erosion this basaltic lava soil has been eroded step wise which is often termed as Deccan trap.

How was Deccan Plateau formed name the ranges included in the Deccan Plateau?

The Deccan Plateau is a plateau situated between two mountain ranges, the Western and Eastern Ghats, in southern and western India. Its northern boundary is formed by the Satpura and Vindhya ranges.

Is Deccan trap a part of Deccan Plateau?

The flood basalt province known as the Deccan Traps is located on the Deccan Plateau in west-central India and is one of the largest volcanic provinces in the world. The Deccan Plateau consists of more than 2000 m-thick succession of flat-lying basalt lava flows and covers an area of nearly 500 000 km2.

How is the formation of the Deccan Plateau related to the mass extinction of dinosaurs 65 million years ago?

The Deccan basalts may have played a role in the extinction of the dinosaurs. Most of the basalt was erupted between 65 and 60 million years ago. Gases released by the eruption may have changed the global climate and lead to the demise of the dinosaurs 65 million years ago.

What are the features of Deccan Plateau?

(i) The Deccan Plateau is a triangular landmass that lies to the south of the river Narmada. (ii) The Satpura range flanks its broad base in the north while the Mahadev, the Kaimur hills and the Maikal range form its eastward extension. (iii) It is higher in the west and slopes gently eastwards.

Which type of soil is found in Deccan plateau?

Hint: The soils of Regur are primarily present in Central India and the Deccan Plateau. The land is sufficient for growing cotton. Calcium carbonate, magnesium carbonate, potash, and lime are rich in these soils. Complete answer: It is also known as regur, the black dirt.

What is the slope of Deccan Plateau?

Explanation: The slope of the Deccan plateau of India is in West direction.

How are plateaus formed Upsc?

Tectonic plateaus are formed from processes that create mountain ranges – volcanism (Deccan Plateau), crustal shortening (thrusting of one block of crust over another, and folding occurs.

Why is the Deccan Plateau important?

The Deccan Plateau is believed to be an ancient remnant of the Earth’s original continent, Gondwanaland, which broke up to create the continents we know today. The plateau is a great ancient shield of basalt lava that now bears the scars of its long exposure to the weathering effects of wind and water.

What causes plateau formation?

Plateaus are sculpted by geologic forces that lift them up and the wind and rain that wear them down into mesas, buttes, and canyons. … Plateaus are built over millions of years as pieces of Earth’s crust smash into each other, melt, and gurgle back toward the surface.

What are 3 types of plateaus?

• Types of Plateaus.
• Dissected Plateaus.
• Tectonic Plateaus.
• Volcanic Plateaus.
• Deccan Plateaus.

What landforms form the boundary of the Deccan Plateau?

The Deccan Plateau is shaped like an inverted triangle and is bounded by the Western Ghats in the west; the Eastern Ghats in the east; the Satpura and the Vindhya Mountain ranges in the north. The plateau’s northeastern boundary is formed by the watershed between the Mahanadi and the Godavari Rivers.

Which states are included in Deccan Plateau?

It extends over eight Indian states which are Maharashtra, Telangana, Andhra Pradesh, Tamil Nadu, Karnataka, and Kerala. The uplands which are the areas of higher landmass form a triangle that is nested in the familiar downward-pointing triangle of the Indian sub-continent’s coastline.

Which of these states is not included in the Deccan Plateau?

The Deccan Plateau is a large plateau that covers most of South India. It is triangular, surrounded by three mountain ranges. It extends over eight Indian states (principally, Telangana, Maharashtra, Andhra Pradesh, Karnataka, Kerala and Tamil Nadu).

Which river is mainly dividing the Deccan plateau from the Central Highlands?

Explanation: The River Narmada originating from the Amarkantak Plateau divides the Peninsular Plateau into two parts: the Central Highlands and the Deccan Plateau.

How were Sundarbans and Deccan trap formed?

They were formed due to the huge deposit of silt by the Ganga, Brahmaputra and Meghna rivers. … This along with the deposition of alluvial silt brought by the major rivers led to the formation of the Sundarbans. The Deccan Traps were formed by the lava from the volcanic eruptions.

What rocks are in the Deccan plateau?

The Deccan plateau is made up of basalt rocks.

What is Deccan lava?

Deccan volcanism produced the longest lava mega-flows on Earth, spanning over 1500 km from the main Deccan province across India to Rajahmundry and out into the Gulf of Bengal. Four to five of these longest lava flows occurred just prior to the KTB mass extinction.

Which is the longest river in the Deccan plateau?

The river Godavari, the largest of the peninsular rivers, and third largest in India, drains about 10% of India’s total geographical area. The catchment area of the river is 3,12,812 sq.km.

Which type of volcanic eruption caused Deccan trap formation?

Answer: Caldera type of volcanic eruption has caused deccan trap formation. Explanation: Calderas are the volcanoes that are most explosive.

Where is the Deccan trap located How has this region been formed?

Answer: The Deccan trap region lies in the north-western part of the Deccan Plateau, extending over Maharashtra and parts of Gujarat, Karnataka and Madhya Pradesh. The Deccan Trap region was formed when it was covered by sheets of lava, which flowed out through cracks millions of years ago.

Which of the following geological periods the volcanic lava flow took place in Deccan plateau of India?

The correct answer is Cretaceous. The Deccan’s volcanic basalt beds were laid down in the massive Deccan Traps eruption. It occurred towards the end of the Cretaceous period between sixty-seven and sixty-six million years ago.

How does the Deccan plateau contribute to the Indian economy?

The Deccan plateau is the region which is rich in minerals and it makes India a mineral rich country. It led India into the list of industrially developed countries. Much of the India’s electricity needs are being satisfied by the hydro – power projects situated in peninsular rivers.

Why do rivers of Deccan plateau flow from west to east?

– The main rivers, the Godavari, Krishna, and Kaveri (Cauvery), flow east to the Bay of Bengal from the Western Ghats. The climate of the plateau is drier than on the coasts and is arid in places. The flow of the Deccan Plateau rivers indicates its slope from west to east.
