Question

Name two rocks which dissolve completely when exposed rain water ​

Answer 1

Explanation:

The Partition of Bengal in 1947, part of the Partition of India, divided the British Indian province of Bengal based on the Radcliffe Line between India and Pakistan. Predominantly Hindu West Bengal became a state of India, and predominantly Muslim East Bengal (now Bangladesh) became a province of Pakistan.

Answer 2

Answer:

For example, limestone and chalk are mostly calcium carbonate. When acidic rainwater falls on limestone or chalk, a chemical reaction happens. New, soluble, substances are formed in the reaction. These dissolve in the water, and then are washed away, weathering the rock.
