how is natural gas formed

The gas is found in layers of rock with tiny holes - the rock holds the gas like a sponge. To bring it to the surface, gas companies drill down hundreds of feet and pump into pipes.When the dinosaurs and the plants they ate died, the remains were buried under many layers of rock and soil.Over time, the tremendous heat and pressure created by the layers of earth turned the animal and plant matter into natural gas and petroleum (oil).That is why we also call them fossil fuels.
