Question

sedimentary rocks are a major source of crude oil and gas. discuss the process on how crude oil is formed .argue this cases for mining crude oil and petrolium products versers using renewable energy such as solar and wind energy citing pros and cons

Answer 1

Crude oil formation:Crude oil is formed from organic matter. The organic mater was deposited in a marine environment and remained buried under anoxic conditions for 100-400 millions years. Over the years, layers of silt, sand and other sediments settled over the buried organic matter. The increase of pressure and temperature slowly transformed the organic matter into hydrocarbons (kerogen, oil, gas). Also, over those millions of years various plate tectonics (continents drift over the underlying mantle) and other geological phenomena resulted in the rearrangement of oceans and continents; thus, we encounter oil in both onshore and offshore locations.

​​​​​​Mining of crude oil and petroleum product:

Petroleum products are fuels made from crude oil and hydrocarbons contained in natural gas. Petroleum products can also be made from coal, natural gas, and biomass.

After crude oil is removed from the ground, it is sent to a refinery where different parts of the crude oil are separated into useable petroleum products. These petroleum products include gasoline, distillates such as diesel fuel and heating oil, jet fuel, petrochemical feedstocks, waxes, lubricating oils, and asphalt.

Solar energy as a renewable energy:Pros and Cons

Solar is a revolutionary energy solution has its various advantages and disadvantages one should keep in mind. Of all the common benefits and drawbacks that come with going solar, here are a few of the ones that consistently rise to the top:

Top solar energy pros and cons

PROS OF SOLAR ENERGY	CONS OF SOLAR ENERGY
Lower your electric bill	Doesn't work for every roof type
Improve the value of your home	Not ideal if you're about to move
Reduce your carbon footprint	Buying panels can be expensive
Combat rising electricity costs	Low electricity costs = lower savings
Earn money back on your investment	Finding local solar installers can be difficult

Wind Energy as a renewable energy: Pros and Cons

Wind energy is another one of the most commonly used types of renewable energy, and also happens to be one of our fastest-growing sources of electricity. However, while there are a number of environmental benefits to using wind energy, there are some downsides. Here are a few of the top pros and cons:

Pros and cons of wind energy

Pros of wind energy	Cons of wind energy
Renewable & clean source of energy	Intermittent
Low operating costs	Noise and visual pollution
Efficient use of land space	Some adverse environmental impact
