Which of the following correctly explains a positive climate feedback loop found in the Arctic? Options: Increased melting of permafrost increases Earth’s ability to absorb methane gas, which decreases greenhouse warming and decreases the melting of permafrost. Increased global temperatures lead to decreased sea ice coverage and decreased albedo, which further increases global temperatures. Increased evaporation and cloud formation decreases the amount of solar energy reaching the surface of Earth, which leads to cooler temperatures at the surface and decreased evaporation and cloud formation. Increased precipitation increases the size of high albedo snowpack in polar regions, which leads to increased habitat for Arctic organisms such as polar bears.

Increased global temperatures lead to decreased sea ice coverage and decreased albedo, which further increases global temperatures.

If Earth's axis changed from 23.5 degrees to 20 degrees, what would be expected to occur?

Which of the following accurately describes a benefit of concentrated animal feeding operations (CAFOs)? Options: 1. Concentrated animal feeding operations produce a large amount of manure, which is then often held in large manure lagoons. 2. The animals raised in concentrated animal feeding operations are usually grass-fed and therefore less susceptible to disease. 3. Concentrated animal feeding operations are efficient and relatively low-cost facilities that help keep consumer costs low. 4. When animals are kept in large concentrations in a small area, the water quality of local waterways is protected from excess runoff.
