Q: - Coal is burned in a boiler - Steam is produced under pressure - Flows into a turbine - The turbine spins What might be the last step of the process?
A: Creates electricity.

Q: - Dead organic material accumulates on the bottom of oceans, riverbeds or swamps, mixing with mud and sand - Over time, more sediment piles on top - The resulting heat and pressure transforms the organic layer into a dark and waxy substance known as kerogen - Left alone, the kerogen molecules eventually crack - The molecules break up into shorter and lighter molecules composed almost solely of carbon and hydrogen atoms What might be the last step of the process?
A: It will turn into either petroleum or natural gas

Q: - An area is at a higher elevation than the surrounding area - Rain falls - Water is in the area of high elevation - The water creates a stream - The stream moves towards lower elevation - The stream continues along the same path for a long time - The soil and rocks erode where the stream touches them - The stream moves deeper into the soil What might be the last step of the process?
A: The stream is smaller than the eroded area.

Q: - You must decide the purpose of the satellite - You must draw up a plan to what kind of orbit the satellite will travel - You make preparations for the rocket that will travel into space - Prepare the crew that will send it there - You begin the countdown date for the rocket - And then you send the rocket carrying the satellite into space What might be the last step of the process?
A:
Once in orbit the satellite will be placed where it was planned.
