GEOLOGY

Detailed explanation-1: -Glacier ice covers only about 10 percent of Earth’s land surface at the present time, but it was up to three times as extensive during the Pleistocene Ice Age.

Detailed explanation-2: -Today, glaciers cover approximately: 3% of Earth’s surface. 11% of Earth’s land area.

Detailed explanation-3: -Glaciers cover about 10% of Earth’s land surface. Continental glaciers cover nearly 13 million km2 (5 million sq mi) or about 98% of Antarctica’s 13.2 million km2 (5.1 million sq mi), with an average thickness of 2, 100 m (7, 000 ft). Greenland and Patagonia also have huge expanses of continental glaciers.

Detailed explanation-4: -Ice, which covers 10 percent of Earth’s surface, is disappearing rapidly. Select a topic below to see how climate change has affected glaciers, sea ice, and continental ice sheets worldwide.

Detailed explanation-5: -The ocean covers more than 70 percent of the surface of our planet. It’s hard to imagine, but about 97 percent of the Earth’s water can be found in our ocean. Of the tiny percentage that’s not in the ocean, about two percent is frozen up in glaciers and ice caps.
