Question

overview of earth system
positive feedback loops can drive a system to extremes and exacerbate negative consequences, while negative feedback loops maintain balance in a system.
melting sea ice can cause more sunlight to be absorbed by our planet, which increases temperatures, which can cause more melting of sea ice. this is an example of which type of feedback loop?
negative
positive

Explanation:

The description states that melting sea - ice causes more sunlight absorption, which increases temperatures and leads to more sea - ice melting. This is a cycle that drives the system (Earth's climate system here) towards an extreme (more warming), which is the characteristic of a positive feedback loop.

Answer:

Positive
