Final answer:
Huge volcanoes were present in India at the end of the Cretaceous, contributing to the climate change and mass extinction of the era.
Step-by-step explanation:
Huge volcanoes were present at the end of the Cretaceous in India. This period is known for the extensive volcanism that began forming about 66 million years ago, roughly coinciding with the Yucatan asteroid impact. The volcanic activity resulted in the Deccan Traps, where lava flows covered over 50% of what is now India. The release of volcanic gases, especially sulphur dioxide, during this period contributed to significant climate change, and is believed to have played a role in the mass extinction event that marked the end of the Cretaceous and the end of the era of the dinosaurs.
