Answer:
Processes responsible are Climate change and global warming.
Step-by-step explanation:
- Greenland covers an area of 1,710,000 square kilometers 80% of the surface of the earth. It is similar to Antarctica in many ways as both of them from the north an south poles.
- The presence of ice caps and sheets of ice on rock masses of Antarctica and Greenland are nowadays exposing to the solar radiation and warm winds coming from equatorial regions.
- Processes like these are continuously acting over these two areas and hence melting ice and deleting freshwater reserves. Bare earth now can be seen along with the cracks in the continental floors.
- Since the impact of the melting of polar caps the ice sheets have shrunk in size and global sea level is projected to rise about 7.2 meters above average. An examination of 32 outlets, of polar regions, shows us rise in global waters from 1 to 3 degrees temperature, hazardous for nation borders along coasts.
