Why is the Deccan trap so called Where is it located for what is this area important?
The black soil area in the peninsular plateau is called the Deccan Trap. ... These rocks have been denuded over time and are responsible for the formation of the black soil. Due to continuous flow of lava an extensive lava plateau has been formed known as Deccan Trap.
What is the Deccan trap also known as?
Basaltic lava flows , known as the Deccan Trap, cover about one million cubic kilometers of the western Indian platform.
Is Deccan trap also known as Deccan plateau?
The Deccan Plateau, a Precambrian shield, is partially covered by the Deccan Traps, a large igneous province . The northwestern part of the plateau is made up of lava flows or igneous rocks known as the Deccan Traps.
What is the importance of Deccan Trap?
(4) The Black soil formed over the Deccan trap is a rich soil particularly suitable for raising cotton . (5) It is rich enough in alumina to be high grade bauxite. Bauxite is useful in Petroleum filtration and in the manufacture of aluminium and alumina cements.
Which soil is associated with Deccan Trap?
The Deccan Traps of India are formed of normal augite basalt, which on in situ decomposition and a long cycle of secondary changes has resulted in a soil highly expansive in nature. The soil is commonly known as Black Cotton Soil .
Can Deccan Traps erupt?
The Deccan Traps date back to around 66 million years ago , when magma from deep inside Earth erupted to the surface. In some parts of the Deccan Traps, the volcanic layers are more than two kilometers (1.2 miles) thick, making this the second-largest volcanic eruption ever on land.
Which is black soil?
Black soils are mineral soils which have a black surface horizon , enriched with organic carbon that is at least 25 cm deep. ... A base saturation in the black surface horizons ≥50%.
Are the Deccan Traps still active?
Deccan Traps, India
This hotspot is still active today and last erupted on April 7, 2007. The DVP is one of the largest volcanic eruptions in Earth history and today covers an area of 500,000 km2, or about the size of France, or Texas.
Which is highest plateau in the world?
It towers over southwestern China at an average elevation of 4000 m above sea level and is known as “the roof of the world.” Covering more than 2.5 million km(2), the Qinghai-Tibetan plateau is the highest and largest plateau in the world.
Which is the oldest plateau in India?
The Deccan plateau in India is one of the oldest plateaus.
How did Deccan plateau form?
The Deccan plateau emerged from volcanic activity that continued for millions of years. The lava built up and cooled, and over time, the layers created the Deccan plateau. The Tibetan Plateau continuously formed through the collision of two tectonic plates, the Indo-Australian and the Eurasian plate.
What is Deccan trap Class 9 Ncert?
The black soil area of Peninsular Plateau is known as Deccan Trap. This is of volcanic origin , hence the rocks are igneous. These rocks have denuded over time and are responsible for the formation of black soil.
Which type of volcanic eruption caused Deccan trap?
Answer: Caldera type of volcanic eruption has caused deccan trap formation. Explanation: Calderas are the volcanoes that are most explosive.
Why was Deccan trap region black soil?
The black soil is found in the Deccan trap region because this region is formed due to the deposition of lava produced by the volcanic eruption . When lava rocks breaks down into finer particles due to weathering, it results in the formation of the black soil.
Is black soil of Deccan Trap a potential resource?
Answer: The black soil is also called the Regur Soil or the Black Cotton Soil. ... Black soil is formed from the weathering of the igneous rocks. The black soil is mostly found in the Deccan Trap, covering large areas of Maharashtra, Chhattisgarh, Gujarat and Madhya Pradesh.
