Planet Earth Structure – thinking skills task
In this task you need to look at the statements that relate to the different layers of the earth’s structure. Each statement has something to do with the layer, it’s depth, temperature and hardness. Remember that it gets hotter towards the centre and think about how this might affect the physical structure of the rock.
Three of the boxes have been completed to help you. Write the correct statement in each box – if you are not sure about the answer then ask a teacher! 4 3 2 1
