Non-renewable resources took millions of years to form. - About two billion years ago, marine organisms such as algae and microscopic animals and plants died and settled on the ocean floor. - These organisms eventually turned into a substance called karagin under heat and pressure. - Karagin gradually transforms into oil or gas, a process that typically takes at least a million years. - Oil and gas are hydrocarbons made up of hydrogen and carbon atoms at the molecular level. - The Earth's crust's constant pressure and movement squeeze oil and gas through the pores within rocks. - Some oil and gas natural seep out onto the Earth's surface, while others get trapped beneath impermeable layers or rock structures like faults and folds. - Oil or gas deposits accumulate and form reservoirs, which can be as large as a city. - Geologists utilize various survey techniques to find oil and gas deposits, including seismic surveys, gravitational surveys, and geological mapping. - Seismic surveys involve using reflected sound waves to create a 3D view of the Earth's interior. - Advanced technologies like four-dimensional projections and graphic renderings enhance our ability to locate conventional oil and gas deposits. - Unconventional oil and gas refer to energy resources that are currently challenging or expensive to extract. - In a world with limited energy resources, people are exploring more efficient ways of accessing unconventional oil and gas or alternative and renewable sources of energy. - Examples of alternative and renewable energy sources include biofuels and solar power. - Speculating on the energy sources of the future, what do you think will be next?
