What significant change in glaciation occurred around 13 million years ago? Antarctic glaciers grew substantially Glacial ice disappeared from Greenland Glaciers appeared in the high Andes Ice sheets appeared in the Northern Hemisphere None of the answers is correct

The last glacial period was at the end of 115,000-11,700 years ago. This was a part of a larger sequence of glaciation and interglacial periods that are known as quaternary glaciation. This glaciation began about 2.58 million years ago and resulted in the formation of arctic caps. During this period there was an advance and retreat of glaciers. During this period the last glacial maximum was reached about 22,000 years ago. The occurrence of the third ice age that was most severe occurred between 720 to 635 million years ago. This leads to what is knows as the snowball earth that was complete covered by ice. The late Cenozoic period was an extensive ice age and was marked by extensive ice sheets in Antarctica in the last 34 million years ago. After which the ice sheets appeared in the northern hemisphere known to extensive glaciation. The growth in Antarctica ice sheets was extensive and covered parts of Europe and North America. This suggests that Antarctica glaciers, which grew substantially and covered the entire Antarctica continent. The causes of the glaciation were due to the cooling and the long-term trends eventually led to glaciation. The rise of mountains and plate tectonic events were also responsible that led to the long-term development of the ice age.Hence the changes during the period led to the growth of extensive ice sheets and glaciers in Antarctica. With the effects seen in the form of glacial akes and drainage system. Large lakes were created near the glacial margins in North America and Europe. These lakes can be seen even today.
