Figure: Typical snapshot of incremental reading. While learning about the greenhouse effect, the student extracts the fragment saying that "An ideal thermally conductive blackbody at the same distance from the Sun as Earth would have a temperature of about 5.3 °C. However, because Earth reflects about 30%^[5][6] of the incoming sunlight, this idealized planet's effective temperature (the temperature of a blackbody that would emit the same amount of radiation) would be about −18 °C.^[7][8] The surface temperature of this hypothetical planet is 33 °C below Earth's actual surface temperature of approximately 14 °C.^[9]. The mechanism that produces this difference between the actual surface temperature and the effective temperature is due to the atmosphere and is known as greenhouse effect". The extracted fragment will inherit illustrations placed on the right, as well as article references. The student can move on to reading another article by pressing Enter. The picture on the right is stored locally in the image registry (on the user's hard disk) and can be reused to illustrate other articles or questions.
