Answer:
The relationship between the warming of the earth’s northern latitude and ice is a practical example of a positive feedback on the earth system.
Explanation:
A positive feedback is a process that brings about an increase in the process of interaction in the earth activities The warming of the northern latitude which is responsible for generating more heat through sunlight with time, usually results in an increase in the melting of ice bodies in the ocean by movement.
