1 1 2 3 Write down three observations and an inference Write down two observations Example : There are three candles

2 Why did the candles blow out? Let’s investigate a similar situation…

3 Lake Nyos, 1986

4 Where is Cameroon? Cameroon is located under a region of volcanic activity

5 Where is Cameroon? The volcanic activity created a chain of islands The volcanic activity creates volcanoes on land

6 What is a volcano? Magma rises up, cutting a cylinder in the Earth When it reaches the surface, it may cut a hole in the surface and erupt lava and rock

7 How did Lake Nyos form? Magma may hit wet rock and explode, causing craters These craters may fill up with water

9 Carbon Dioxide

10 CO 2 Carbon Dioxide is denser than Oxygen… O2O2 O2O2 O2O2 O2O2 O2O2 O2O2 O2O2 O2O2 O2O2 O2O2 CO 2 = Carbon Dioxide O 2 = Oxygen
