Create an image that represents the process by which oil is formed. Petroleum is mainly formed from underground organic matter under the influence of pressure and temperature. Reflecting this, select an underground image as the background and express a depth of hundreds of meters or more underground. Please capture the process of organic matter decomposing and changing into petroleum under the influence of pressure and temperature. Also, visually express the underground environment and process where oil is formed to create a realistic feel. By doing this, you create an image that represents the process of creating oil. --s 250
