Sink

Imagine you're trying to keep your home cool on a hot summer day by using fans and keeping the windows open. Just as the cool breeze from outside transfers heat away from your living space, helping to maintain a comfortable temperature, a 'sink' in Earth science refers to a process that removes heat, energy, or substances from the Earth system. In this analogy, your home represents the Earth system, the heat inside is like the energy or substances that need to be removed, and the fan and open windows act as the 'sink,' facilitating the transfer and removal of excess heat to maintain balance.
