Final answer:
Most of Earth's ice is located in the Antarctic ice sheet (90%), followed by the Greenland ice sheet (10%), with less than half a percent in global glaciers.
Step-by-step explanation:
The majority of segregated ice masses on Earth are found in specific regions. According to the properties of surface mass components of Earth, about 90% of the ice volume is located in the Antarctic ice sheet. Another significant portion, approximately 10%, is found in the Greenland ice sheet, and the remaining portion, which is less than half a percent, is contained within glaciers around the world.
In addition to Earth, there is evidence of large quantities of ice below the surface of Mars, particularly in its mid-latitudes, suggesting potential for future human exploration. During past ice ages, the Northern Hemisphere experienced extensive glaciation, which can be visualized in computer-generated imagery showing vast frozen areas. Furthermore, sub-glacial lakes like Lake Vostok exist beneath the Antarctic ice sheet, raising questions about potential aquatic life in such extreme environments.
