Final answer:
As snow melts and exposes darker-colored pavement, a positive feedback process occurs where the dark pavement absorbs more sunlight, leading to further warming and melting of snow, reinforcing the initial effect.
Step-by-step explanation:
Yes, I would expect a feedback process to result from the situation where snow melts on a city street and exposes darker-colored pavement. The feedback process involved is a positive feedback process.
As the snow melts, the exposed darker pavement absorbs more sunlight and heat compared to lighter-colored surfaces, which leads to further warming of the pavement. This warming can lead to an accelerated melting of the surrounding snow, which in turn exposes even more dark pavement. The cycle of melting and exposure of dark surfaces continues, reinforcing the initial effect of the melted snow and the warming of the pavement. This is an example of a positive feedback loop where the initial process (melting of snow) is amplified by the subsequent changes (exposure of dark pavement and increased absorption of sunlight).
