The solar constant in summer is 1,320 W/m² - the solar constant in winter is 1,420 W/m² 1. Draw a figure showing the movement of the earth around the sun once a year 2. Integrate the declination of the rotation axis of the earth around itself once a day in relation to the direct way of the sunlight towards the earth in the same figure 3. Look to the northern part of our planet, explain now why it is cold in winter, and warm in summer although the solar constant in winter is higher than in summer. • Therefor look to the daily time of sunshine, the angle of the incoming sun light and the length of the way of the sunlight through the atmosphere and explain the impact on the energy supply from the sun to the earth's surface.
