Q & A
What are the primary sources of energy that currently power our transportation and electricity?
-The primary sources of energy that currently power our transportation and electricity are fossil fuels like coal, oil, and gas.
How are fossil fuels such as coal, oil, and gas formed?
-Fossil fuels are formed from the remains of marine organisms like algae and microscopic animals and plants that died and settled on the ocean floor millions of years ago, transforming into substances like kerogen under heat and pressure.
What is the process through which kerogen changes into oil or gas?
-Keratin changes into oil or gas over millions of years under the influence of heat and pressure, a process that can take at least a million years.
How are oil and gas different from each other at the molecular level?
-Oil and gas are both hydrocarbons, but they differ in their molecular structure and composition, with oil being a liquid and gas being a vapor at atmospheric conditions.
What geological processes cause oil and gas to move through the Earth's crust?
-The constant pressure and movement of the Earth's crust squeeze oil and gas through the pores or spaces between rocks, sometimes reaching the surface or being trapped beneath impermeable layers.
What is the term for a large underground accumulation of oil and gas?
-A large underground accumulation of oil and gas is called a reservoir, which can be as large as a city and acts like a vast sponge filled with these resources.
How do geologists locate oil and gas deposits?
-Geologists locate oil and gas deposits using various survey techniques, including seismic surveys, gravitational surveys, and geological mapping.
What is a seismic survey and how does it help in finding oil and gas deposits?
-A seismic survey uses reflected sound waves to produce a 3D view of the Earth's interior, helping to identify potential oil and gas deposits.
What are some new technologies that are improving the way we find conventional oil and gas deposits?
-New technologies such as four-dimensional projections and sophisticated graphic renderings of rock structures are enhancing the methods used to find conventional oil and gas deposits.
What are unconventional oil and gas resources, and why are they being considered?
-Unconventional oil and gas resources are those that are currently difficult or expensive to extract. They are being considered due to the world's limited energy resources and the need for more efficient extraction methods.
What alternative and renewable sources of energy are being explored as potential future energy sources?
-Alternative and renewable sources of energy being explored include biofuels, solar power, and other sustainable options as the world seeks to diversify its energy portfolio.

π Fossil Fuels: The Energy of Today
This paragraph discusses the role of fossil fuels like coal, oil, and gas in meeting the world's energy needs. It explains that these non-renewable resources formed millions of years ago from marine organisms that, under heat and pressure, transformed into hydrocarbons. The process involves the conversion of keratin into oil or gas over a million years. The Earth's crust movement pushes oil and gas through rock pores, sometimes to the surface or trapping them in reservoirs. Geologists use various survey techniques, including seismic and gravitational surveys, to locate these reservoirs. The paragraph also touches on the search for more efficient ways to extract energy from unconventional sources or explore alternative and renewable energy options.
