One revitalization method is to just let nature retake the area. For example, in the Amazon-Cerrado transition, where the Amazon rainforest meets the forest-savanna borderlands, researchers used carbon dating to look at the last 1,600 years of plant growth.They said“Our data indicate a regio...
In terms of radiocarbon dating, the fewer C-14 atoms in a sample, the older that sample is. Nowadays many scientists depend on radiocarbon for dating age-old objects. A.Right B.Wrong C.Not mentioned 点击查看答案 第6题 听力原文: Forests are of great importance to our environment because ...
Carbon dating indicated that the man died 5, 300 years ago. Today, he is known as the Iceman and nicknamed "Ötzi" for the Ötzi Alps where he was found. Kept in perfect condition by the ice, he is the oldest complete human body found on earth. His body has ...
