Final answer:
Permanent, frozen ice on Earth can be found in Antarctica and Greenland, which have extensive ice sheets. Antarctica is also classified as a desert with minimal precipitation, and these ice masses play a key role in studies of climate change.
Step-by-step explanation:
Places on Earth where permanent, frozen ice can be found include Antarctica and Greenland. These regions are known for their extensive ice sheets, with Antarctica's ice sheet being more than a mile thick and containing about 70 percent of the Earth's fresh water. Despite its icy conditions, Antarctica is classified as a desert due to its very low precipitation levels. Greenland also harbors a significant amount of the Earth's ice, particularly within its ice cap, which covers most of the island. These permanent ice masses are critical to understanding climate change, as they significantly contribute to global sea levels and reflect sunlight, influencing the Earth's temperature. Both the Sahara Desert, Gobi Desert, and the Great Basin Desert are examples of deserts, but they do not have permanent ice; the Sahara and Gobi are subtropical deserts, whereas the Great Basin is a cold desert that may experience temporary snow in winter.
