Natural Gas
Natural gas explained in an easy to understand way:


Imagine you're trying to get the last bit of toothpaste out of a nearly empty tube. Just like squeezing that tube to extract the remaining toothpaste, extracting natural gas involves accessing and releasing the fuel trapped within the layers of underground rock. The rock layers act like the walls of the toothpaste tube, holding the natural gas, while the extraction process is akin to the squeezing action needed to access what’s inside.
