What would happen if all of Earth's ice melted? As Earth gets (hot) every year, the planet's ice suffers. The ice is melting faster than ever. Sea ice is (main) in the Arctic. This kind of ice is made of salty seawater. Land ice is mostly in Greenland and Antarctica, is made of fresh water. Sea levels will rise to 50 to 85 meters, (cause) many global changes. (city) near the sea will disappear. Sea animals will have no homes. Earth will move around more slowly. We will have longer days because two milliseconds (add) to each day. Global temperature will rise by 3. 5℃. Poisonous chemicals from some ice will go into rivers and oceans.
Only 30 percent of water on Earth is fresh, about 70 percent of that is (freeze). That's 30 million cubic km of ice. Using this kind of ice (build) a 1000- meter-thick wall, would cover North America.
