Question

Which is the oldest mountain range of India?
A.Aravallis
B.Maikal
C.Himalayas
D.Mahadev

Answer 1

Hint:Almost 1.8 billion years ago the Aravalli mountain range was formed due to the collision of tectonic plates below the surface of Earth. This mountain range runs from the Northeast to the southwest direction across Rajasthan.

Complete answer:
A series of old fold mountains in the western part of India is the Aravallis. They stretch from Haryana to Gujarat and cover parts of Madhya Pradesh and Rajasthan. This mountain range starts from Delhi and passes through Southern Haryana and Rajasthan and finally ends in Gujarat and thus runs approximately 692 km in a southwest direction. Guru Shikhar and Mount Abu are the mountain peaks of the Aravalli range where Guru Shikhar is the highest peak at 1722 metres. There is a humid subtropical climate in the Northern Aravali range in Delhi and Haryana. There is an arid and dry climate in the central Aravali range in Rajasthan and a tropical wet and dry climate in the southern Aravalli range in Gujarat. Luni River that originates in the Pushkar valley near Ajmer and flows into the Rann of Kutch and the tributaries of Yamuna namely Banas and Sahibi rivers are the three major rivers that flow from the Aravalli. From the Western slopes of the Aravalli range in Rajasthan originates the rivers that flow from north to south. From the Western slopes of the Aravalli range in the Udaipur district originates the Sabarmati river that flows into the Gulf of Cambay of the Arabian sea.

Hence, the correct answer is option (A).

Note:When the Indian plate was not connected to The Eurasian plate the Aravalli range was formed which is one of the oldest mountain ranges in the world. In between the Indian plate and The Eurasian plate, there was an existence of Tethys sea. In composition the release and African plateaus are similar.
