Answer 2

Answer:

The increasing temperature would have been the cause of the melting of the giant ice during the Paleozoic era. According to scientists, the temperature of the earth might have increased with much more release of CO2 than today. With the increase in the temperate led to the massive evolution of life on earth. The reason for the change in climate was the continental shift. Continents broke apart with formed mountains and crating volcano activities.
