How did the formation of Gondwana impact the Earth's geography?
The formation of Gondwana led to the aggregation of several landmasses into a single supercontinent, influencing the Earth's geography significantly.
What is the significance of Gondwana in the geological context?
Gondwana is a supercontinent that existed in the past and played a crucial role in shaping the Earth's landmasses.
How are Upper and Lower Gondwana sub-divided?

Name the three tectonic subdivisions of the Himalayas.
The Greater Himalaya, the Lesser Himalaya, and the Sub-Himalaya or Siwalik Range are the three tectonic subdivisions of the Himalayas.
What are some key features of Gondwana deposits that distinguish them from other geological formations?
Gondwana deposits are characterized by their unique fossil content and stratigraphic significance compared to other geological formations.
Why is the Hadean to Palaeoarchaean record missing from the Indian stratigraphic succession?
The Hadean to Palaeoarchaean record is missing due to intense tectonism and associated metamorphism and magmatism.
What geological processes led to the absence of Hadean to Palaeoarchaean record in the Indian stratigraphic succession?
Intense tectonism, metamorphism, and magmatism.
Explain why the Indian stratigraphic succession does not contain the Hadean to Palaeoarchaean record.
The intense tectonism, metamorphism, and magmatism in the region destroyed or altered the original rocks from that period.
Which geological events caused the disappearance of the Hadean to Palaeoarchaean record in India?
Intense tectonism, metamorphism, and magmatism.
What geological factors contributed to the absence of the Hadean to Palaeoarchaean record in Indian rocks?
Intense tectonism, metamorphism, and magmatism.
