Total volume : 1. 65 + 3. 2 = 1. 68 gt flux rate: 0. 2. Describe the significant changes in the amount of solar radiation striking the earth caused by the variation in the earth"s orbit. E=0 if the earth"s orbit it 0, the earth"s is e=0. 07 (max) Impact : changing the solar insolation/radiation by 6. 4% per year and it s changing the intensity of the seasons. In a circle : not much change with seasons. axial tilt/obliquity. Varies approximately 2. 4 over a period of 41 000 years. The greater the tilt, the more impacts the solar energy received by the pole; Glaciers 1 pole and de-glaciate the other.
