Once upon a time, mammoths, sabre-toothed tigers and other extraordinary animals roamed the earth. Before man, other species reigned on this blue planet. However, there is evidence that species that lived here many years ago have ceased to exist today. The ideas of evolution and destruction still lead us to ask questions about the events that have affected our planet. Throughout our world's history, we can see evidence of past ice ages that have allowed us to deeply examine our history, not only as a human race, but as life in general. Many scientists, geologists and theorists have tried to understand what our planet has in store next. They analyzed the possibility of a large ice cover also known as an ice age. Through the history of the Ice Age, its causes, and current debates, we can gain insight into what happened and what might happen in the future. What if an ice age happened today? What would happen to humanity? Sometimes the answers may lie in the past, but will this history repeat itself, causing mass destruction of the world as we know it? When analyzing future ice ages, it is crucial to understand their past. Ice ages date back to the appearance of the first form of life, approximately 3.6 billion years ago. According to science and other studies, Earth has experienced eleven ice ages. Although some last longer than others, they all result in the same effect: global glaciations. It's difficult to explain what actually causes ice ages, although there are many theories. This is a rare phenomenon that occurs over approximately 150,000 years and lasts for a few million years. So, if that’s the case, why are so many people worried about it today? It could be that although scientists, geologists and theorists have an idea of ​​where...... middle of article ......, the equator, the north and south poles were in different places throughout history. of the world. Plate movements can cause continental blocks to uplift. These uprisings can change the characteristics of the ocean and atmosphere. With such changes, the climate is also affected. Scientists believe that this is a factor favoring the development of ice ages. A. Wegener proposed the theory of continental drift in 1922. He considered that if continents could slide around the globe, this could bring them to regions with colder climates. As a result, ice sheets could develop. With Wegener, AP Coleman presents the theory of elevation change. Coleman wrote: “The theory requires that all the land in the world was raised 3,000 feet and then lowered again three times. » Higher altitude is directly associated with less humidity in the atmosphere.
