1 Formation of Fossil Fuels
Earth and Space 1 In addition to long periods of time, all of the following are necessary for the formation of fossil fuels EXCEPT – A extreme heat B organic matter C fresh water D intense pressure 5.7A 2 Coal often forms where once there were swamps. What characteristic of swamps is important to the formation of coal? A High temperatures B Abundant plant life C Frequent rains D Reptile predators

2 What changes buried organic matter into fossil fuels?
Formation of Fossil Fuels Earth and Space 3 What changes buried organic matter into fossil fuels? A Industrial pollution B Ocean currents C Volcanic activity D Heat and pressure 4 A student creates a model of the formation of fossil fuels by first placing a layer of leaves, representing organic matter, in the bottom of a cup. What step will come next in the model? A Pouring water over the leaves to model washing away by rivers B Adding sand on top of the leaves to model burial in sediments C Burning the leaves to model the decay of the organic matter D Putting the leaves in the freezer to model conditions on top of mountains

3 Which layer formed first?
Formation of Fossil Fuels Earth and Space 5 Several layers of sedimentary rock are illustrated. They are in the same order as when they first formed. Which layer formed first? A Rock Layer W B Rock Layer X C Rock Layer Y D Rock Layer Z
