In our latest Earthlearningidea, the diagram shows how oil and gas are formed, how they become trapped in the ground and how they may be extracted. Pupils are asked to list the events in the correct order and are given sentences to help. They are also asked to explain how oil and gas might escape from the trap on the right and what would happen if the fault brought the limestone on the right into contact with the sandstone on the left. Lastly they explain what sorts of rock they would be looking for if they were searching for oil and gas.
