Carbon dioxide emissions are contributing to climate change, which is causing average global temperatures to increase. These temperature increases have led to a loss of sea ice in the Arctic. Populations of polar bears, which depend on sea ice as part of their habitat, have declined as a result of this loss. The rate of Arctic sea ice loss is predicted to increase if the current temperature trends continue. What is the best long-term solution to help maintain polar bear populations?

The table presents the average day and night temperatures in five cities. it also reveals whether a city receives substantial rainfall (wet climate) or little rainfall (dry climate). which city’s rocks are likeliest to experience frost wedging, and why? a) city a because the consistently subzero temperature would prevent water from melting b) city b because it is a wet region and the temperature fluctuates around the freezing point c) city c because it receives plenty of rain fall and the weather is moderately cool d) city d because the hot and dry weather would cause rocks to absorb water
