The reason glaciers are melting are because of man-made factors. Green house gas, emissions and aerosols are good examples of what man made factors are melting earths glaciers.
The changes in land use associated with urban development affect flooding in many ways. Removing vegetation and soil, grading the land surface, and constructing drainage networks increase runoff to streams from rainfall and snowmelt. As a result, the peak discharge, volume, and frequency of floods increase in nearby streams. Changes to stream channels during urban development can limit their capacity to convey floodwaters. Roads and buildings constructed in flood-prone areas are exposed to increased flood hazards, including inundation and erosion, as new development continues. Information about streamflow and how it is affected by land use can help communities reduce their current and future vulnerability to floods.<span>

The formula to calculate density is as followed:
Density = Mass/Volume
In this case, the equation would be:
Density = 41.2/8.2
Your answer would be "A", 5.02 g/cm (cubed)
Cobalt is an essential material that is mainly used in lithium ion batteries which are found in smartphones and some electric vehicles. Congo provide majority of the worlds supply of cobalt. Although having a surplus of valuable materials, Congo is one of the poorest nations. Because of the lack of money, those who mine cobalt in the Congo do not used power tools, gloves or mask, but instead they use their hands. With that, the miners would be exposed to high level of cobalt. Lung disease and heart failure have been linked to high levels of cobalt, and the mines that produces it are blamed for destroying landscapes, polluting water sources, contaminated crops and a loss of soil fertility.
Hopes this help. Sorry if there is any grammar mistake.
