Question

Consider the possible scenarios and determine which of them are true for positive feedbacks or negative feedbacks. Select the three that apply View Available Hint(s)

Hint 1. Negative vs. positive feedback
Hint 2. Material color and solar reflectivity Select the three that apply

A. Increased evaporation resulting from a temperature rise can produce more clouds which can potentially lead to a positive feedback
B. If ice cover melts due to a temperature rise the result will be decreased albedo or reflectivity which can potentially
lead to a positive feedback
C. Increased plant photosynthesis resulting from a temperature rise can remove carbon dioxide from the atmosphere which can potentially lead to a positive feedback
D. If ice cover melts due to a temperature rise the result will be decreased albedo or reflectivity which can potentially lead to a negative feedback
E. Increased plant photosynthesis resulting from a temperature rise can remove carbon dioxide from the atmosphere which can potentially lead to a negative feedback
F. Increased evaporation resulting from a temperature rise can produce more clouds which can potentially lead to a negative feedback

Answer 1

B. If ice cover melts due to a temperature rise the result will be decreased albedo or reflectivity which can potentially

lead to a positive feedback

E. Increased plant photosynthesis resulting from a temperature rise can remove carbon dioxide from the atmosphere which can potentially lead to a negative feedback

F. Increased evaporation resulting from a temperature rise can produce more clouds which can potentially lead to a negative feedback
