What evidence is there that the O’Higgins Glacier is being affected by global warming? View Available Hint(s) What evidence is there that the O’Higgins Glacier is being affected by global warming? It has retreated nine miles in the past 100 years because of melting. It has grown nine miles in the past 100 years because warmer temperatures have caused melting along the edge of the glacier, allowing it to move more quickly. It has retreated nine miles in the past 100 years because of a dramatic decrease in snowfall at the source of the glacier. It has grown nine miles in the past 100 years because of increased snow pack at extremely high elevations. There is no evidence that the changes of O’Higgins are being affected by global warming.

Option (1)

Explanation:

The glaciers are the frozen freshwater bodies on earth. They are mostly present in the higher latitudes and also at the high elevated areas. The O’Higgins Glacier is located in Chile and it is a National park. The glaciers present at this place have retreated about nine miles in the past 100 years. This is due to the rapid rate of melting which is mainly caused by the global warming effect.

The glaciers are affected because of the high absorption of heat, as well as the burning of fossil fuels, deforestation, and many other factors. This increases the global surface temperature as a result of which the glaciers melt.

Thus, the correct answer is option (1).

f.without carbon-14, james can use relative dating to estimate the age of the fossil.
