Schematically represent the process of oil formation through photographs. First, select a layer hundreds of meters or more underground as the background to give the appearance of the underground. Also, please describe the process by which organic matter is deposited from underground. This organic matter gradually changes under the influence of pressure and temperature. Please describe this. Next, draw a diagram to show the process by which oil is formed. Depict oil moving underground in a vertical or horizontal direction, and show changes in the shape of oil due to changes in pressure and temperature. Lastly, please describe how oil moves underground in a vertical or horizontal direction and accumulates in an appropriate area. By doing this, you can diagram and photograph the process of oil formation." --s 250
