Slide 1:

The Atmosphere Cut out and arrange these paragraphs about the formation of the atmosphere in the correct chronological order. Then draw a picture above each one to explain what is happening. Carbon dioxide levels rise due to pollution. Global warming starts - weather patterns are affected. Life begins in the oceans. Simple plants called cyanobacteria use carbon dioxide in photosynthesis. Ozone forms and oxygen levels start to rise. Earth is a ball of molten rock. No atmosphere is present. Land plants start to appear. Oxygen levels rise rapidly. Earth starts to cool down. Water vapour begins to condense and oceans are formed. Earth is still too hot for any surface water. Its surface is covered in volcanoes. Animals evolve due to the increase in oxygen. Balance between carbon dioxide and oxygen is achieved. The Atmosphere Cut out and arrange these paragraphs about the formation of the atmosphere in the correct chronological order.
