Q: - A machine called a pulverizer grinds the coal into a fine powder - The coal powder mixes with hot air, which helps the coal burn more efficiently, and the mixture moves to the furnace - The burning coal heats water in a boiler, creating steam - Steam released from the boiler powers an engine called a turbine, transforming heat energy from burning coal into mechanical energy that spins the turbine engine - The spinning turbine is used to power a generator, a machine that turns mechanical energy into electric energy - This happens when magnets inside a copper coil in the generator spin - A condenser cools the steam moving through the turbine - As the steam is condensed, it turns back into water What might be the last step of the process?
A: The water returns to the boiler, and the cycle begins again
Question: - Water evaporates from the ground up to the sky - Water droplets are in clouds - The air gets cold - Water droplets turn into ice crystals What might be the last step of the process?
Answer: Ice crystals in clouds stick together and become snowflakes.

Question: - Human beings burn fossil fuels (oil, gas, etc.) - Carbon dioxide from the burning fossil fuels enter the atmosphere - The make-up of the atmosphere changes - Some energy from the sun cannot escape back through the changed atmosphere - The earth begins to heat because of the extra trapped energy - Human beings cut down trees - Human beings do not re-plant the trees - Trees cannot help take the extra carbon dioxide from the atmosphere - The extra trapped energy starts to change the earth's short term weather What might be the last step of the process?
Answer:
Eventually the long-term climate patterns start to change
