Task 2

In the second experiment, pupils should understand that if the same amount of energy falls on an area of various size (demonstrated only two-dimensionally by an arc of different lengths), the surface will be heated differently. In the equatorial area there will be a surplus of heat, while in Polar Regions there will be a shortage. In the case of the rotational axis tilt, the unilluminated part of the Earth‘s surface will be without the direct inflow of solar energy for a long time (half a year) and this deficiency must be compensated by the flow of heat from irradiated areas.
