Answer:
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).
