Please select the best answer from the choices provided

Answer:

Glacial episodes are an example of negative feedback

Explanation:

Glacial episodes are an example of negative feedback. Negative feedback is a regulatory mechanism that counteracts changes in a system, maintaining stability. In the case of glacial episodes, when the Earth's climate cools and glaciers expand, it leads to decreased solar radiation being absorbed by the Earth's surface. This further contributes to cooling and the expansion of glaciers, creating a negative feedback loop.
