Cambridge Secondary (7-9). Stage 8. Science. Learner's Book - Unit 5: Materials and cycles on Earth - Question 61

The photograph shows the body of a baby mammoth, which has been named Yuka. Her frozen body was discovered in 1977 in eastern Siberia. In that part of the world, it is so cold that the lower layers of the soil stay frozen solid all year round. Scientists think that Yuka lived and died about 39 000 years ago, when the temperature was even colder than it is now.
With a partner, discuss why Yuka’s body has been preserved for so long. Be ready to share your ideas with the rest of the class.
