8. Ice covers about 10% of the Earth's surface today. Most ice is found in Antarctica and Greenland.About 20,000 years ago, ice joined the UK to the rest of Northern Europe. As ice spreads out this is called a glacial periods.As ice retreats (smaller during warm times) this is called interglacials. An ice sheet is a thick layer of ice that can cover a whole country including mountains and valleys.FUN FACT! 20,000 years ago the English Channel was dry land.
