[Q]: - Coal is pulverized into fine powder - The coal is mixed with hot air - The coal and hot air are blown into a boiler - The coal and hot air burn over a fire - Highly purified water is pumped through pipes in the boiler - The water turns into steam - The steam presses against turbines - The turbines spin - Electricity is produced. What might be the first step of the process?
****
[A]: Coal is mined out of the ground

[Q]: - Waves have energy that pushes the water and sediment - The sediment can help erode land like sandpaper - Water washes the sediment back - Some sediment is left as sand. What might be the first step of the process?
****
[A]: Waves hit the coast

[Q]: - 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 - It will turn into either petroleum or natural gas - What might be the first step of the process?
****
[A]: Dead organic material accumulates on the bottom of oceans, riverbeds or swamps, mixing with mud and sand

[Q]: - The trees and plants burn - The animals lose their homes - If the animals can not escape, they may die from smoke inhalation - The plants that provide food are gone - The animals have little to eat - What might be the first step of the process?
