South: Freezing and dry with most of its territory being covered in ice
North: Areas were extremely hot and experienced season changes between dry and wet
Plants: Many plants became replaced by drought-resistant plants such as ferns due to the changing seasons]]> 2020-03-17 17:00:04 UTC https://padlet.com/23dushina1/xtqikw1zwszh/wish/463445032 Animals (Biological) 23dushina1 https://padlet.com/23dushina1/xtqikw1zwszh/wish/463486807 As the climate was warming up, many marine animals and terrestrial animals started to diversify after living through the early cold periods of the Permian period.]]> 2020-03-17 17:26:43 UTC https://padlet.com/23dushina1/xtqikw1zwszh/wish/463486807 Animals changing (Biological) 23dushina1 https://padlet.com/23dushina1/xtqikw1zwszh/wish/463516123 Many animals during this time period were cold blooded reptiles and they had to adapt to fluctuations of temperature from between night and day.(Below freezing and around 100 degrees F)

Some were huge weighing over a ton, and some were smaller. However most of them were cold blooded, but over time the smaller versions grew hair as insulants for heat, and became warm-blooded]]> 2020-03-17 17:53:52 UTC https://padlet.com/23dushina1/xtqikw1zwszh/wish/463521428 Extinction 23dushina1 https://padlet.com/23dushina1/xtqikw1zwszh/wish/463821007 The Permian Extinction happened towards the end of the era and into the beginning of the Triassic period. This has been the world biggest extinction ever with the deaths of around 95% of marine life and 70% of land animals. This was all due to the increase of temperature in oceans(around 80 F) and the increase of CO2 in the atmosphere, and clouds of ash from volcanoes disrupting the process of photosynthesis
