We wanted to know in which camp to place expeller pressed oil. What you need to know: The three most popular methods of oil extraction from vegetables, nuts and seeds are : * Chemical solvents * Centrifuge * Screw press (expeller) Often, more than one method is used, this in order to squeeze the most oil out.
Best Answer: Good question. On average clouds reflect 60% of incoming solar radiation which includes short wave UV. The thicker the cloud the greater the reflection, from 60 - 90%. For thin clouds the albedo, or relection is 30 - 50%, which explains why we can still receive UV on cloudy days.

Note how the Sun emits the most radiation in the visible range (with some overlap in the UV and IR) while the Earth emits mostly infrared radiation. The incoming energy from the Sun to Earth is mainly visible sunlight, called the visible portion of the spectrum of electromagnetic radiation.We perceive visible sunlight as colors from violet (short-wave radiation) to red (long-wave radiation).raph showing the mostly visible radiation spectrum emitted from the Sun as seen from the surface of the Earth (left curve) and the IR radiation emitted Earth as seen from space (right curve). Compared it to Figure 1 this graph shows the wavelengths that are absorbed by atmospheric gases, causing gaps in the spectrum.
