which of the following describes a positive feedback loop?
A. temperatures rising cause ice and snow to melt, which causes more heat to be absorbed by the ground, causing temperatures to rise more.
B. Temperatures rising cause ice and snow to melt, causing animals to lose their habitats and making it harder for them to find food.
C. Melting ice causes more sunlight to be reflected into the atmosphere, causing the temperatures on Earth to increase, which then causes more ice to melt.
D. Melting ice causes more carbon dioxide to be absorbed from the air, trapping less heat in the atmosphere, which then causes temperatures to decrease.
