How do ice cores, tree rings & index fossils provide valuable information about the past?

History

Assoli18 [71]3 years ago

Tree rings are annual growth rings and their thickness indicates how growing conditions were for that year. Index fossils in their type and frequency are indicative of the environment that those organisms grew in and how prolific life was then in that environment. Ice cores drilled through glaciers and ice sheets like in Antarctica tell us about such things as the concentration of greenhouse gases like carbon dioxide (as bubbles in the ice layers) and also about climatic  conditions in glacial and interglacial periods.

Why did the strongest maratha rule in India come an end
Gelneren [198K]

Answer:

The empire formally existed from 1674 with the coronation of Shivaji as the Chhatrapati and ended in 1818 with the defeat of Peshwa Bajirao II at the hands of the British East India Company. The Marathas are credited to a large extent for liberating most of the Indian subcontinent from Mughal rule.

Explanation:

Apart from just fighting the battle, the Maratha troops had the responsibility to protect the non-combatants from Afghans. That was the reason why Marathas suffered heavy losses even after the battle. They could not retreat quickly as they were to protect the non-combatants who were accompanying them.
