1. determine whether the following scenario in the earth system represents a positive or negative feedback or response compared to the initial situation. increased atmospheric carbon dioxide causes increased plant growth which removes carbon dioxide and cools the atmosphere. Negative feedback Positive feedback Or neither 2. determine whether the following scenario in the earth system represents a positive or negative feedback or response compared to the initial situation. Global temperature cooling causes more ice cover. This in turn increases the albedo (reflection) rate that causes less solar energy and cooler temperatures. Negative feedback Positive feedback Or neither 3. Determine whether the following scenario in the earth system represents a positive or negative feedback or response compared to the initial situation. Increased atmospheric carbon dioxide causes increased plant growth which removes carbon dioxide and cools the atmosphere. Negative feedback Positive feedback Or neither 4. determine whether the following scenario in the earth system represents a positive or negative feedback or response compared to the initial situation. DDT is used to kill mosquito caterpillar that carries malaria but it affected the ecological balance and the whole food chain in natural ecosystem. houseflies died when they fed on the dead caterpillars. This in turn killed little lizards when they fed on dead houseflies. Finally, the cats that eat the dead lizards died of ddt poisoning. The effect was invasion of dwelling with more and more rats raiding the house for food and carrying the plague. Negative feedback Positive feedback Or neither 5. determine whether the following scenario in the earth system represents a positive or negative feedback or response compared to the initial situation. The arctic sea temperature increases as a result of global warming and causes the ice to melt, the melting of ice reduced the oceans ability to reflect more sunlight, low reflectivity causes the ocean to absorb more heat that raised the temperature of the region. Negative feedback Positive feedback Or neither
