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
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

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
6. determine whether the following scenario in the earth system represents a positive or negative feedback or response compared to the initial situation.
The earth’s temperature got hotter and melted the arctic ice, the melting released co2 and methane to the atmosphere further increasing the earth temperature.
Negative feedback
Positive feedback
Or neither
7. determine whether the following scenario in the earth system represents a positive or negative feedback or response compared to the initial situation.
A pastoral nomad raises more livestock that destroyed the natural vegetation and subsequently the animals die of drought and starvation. group of answer choices
Negative feedback
Positive feedback
Or neither
8. determine whether the following scenario in the earth system represents a positive or negative feedback or response compared to the initial situation.
In the summer months, body temperature and humidity increases causing the body to sweat more, and subsequently, the body temperature to drops.
Negative feedback
Positive feedback
Or neither
9. determine whether the following scenario in the earth system represents a positive or negative feedback or response compared to the initial situation.
More and more people drive gas-operated vehicles, the amount of co2 increased, the level of global temperature increased.
Negative feedback
Positive feedback
Or neither
10. Determine whether the following scenario in the earth system represents a positive or negative feedback or response compared to the initial situation.
Temperature rise leads to drought and wildfires in the forest, more trees die and decompose releasing more co2 to the atmosphere, the release of co2 further exacerbates global warming.
Negative feedback
Positive feedback
Or neither
11. determine whether the following scenario in the earth system represents a positive or negative feedback or response compared to the initial situation.
The air quality was poor before the pandemic broke out, the pandemic forces more people to stop driving and stay at home, the gas consumption plummeted, and the air quality improves.
Negative feedback
Positive feedback
Or neither
12. determine whether the following scenario in the earth system represents a positive or negative feedback or response compared to the initial situation.
Earth warmed up, and more snow fell because of more water vapor in the atmosphere, and that snow then reduced Earth’s temperature.
