He suggested that the planets all orbit around the Sun in perfect circles, as shown in the figure to the right. This offers a much more elegant explanation of retrograde planetary motion than the geocentric model. 2 What would be the next step In the sclentific process for the Copernican hellocentric model? Choose one O A Send a spacecraft to space to verify the model by watching the motion of the planets o B. Make predictions from Copernicus's model, and verify them with observations O C. Promote Copernicus's model to a theory, because it explains retrograde motion OD. Poll the scientists of the time, and accept Copernicus's model as correct if the majority of them agree ith it. 02/18>Explanation / Answer
If the Earth's tilt was 0 degree there would be no seasons. If the Earth's tilt was 90 degree the seasons will be extreme. The Earth's pole would point directly at the sun. The pole will alternate twice each year between pointing directly at the sun and being perpendicular to the sun as the Earth revolves around the sun. When the pole points directly to the sun there will be 24 hours of continuous sunlight and suns angle would be very high. The pole which points directly will suffer extreme hotness whereas the other pole will be in total darkness and extreme cold. The condition will be reversed 6 months later when again the pole will point directly at the sun . When the pole will be perpendicular the current equatorial regions will receive 12 hours of sunlight and 12 hours of darkness and poles would have a low sun angle. The sun will rise in Northern sky and set in South and vice versa( after 6 months when again the pole becomes perpendicular). All locations of earth will receive extreme hot and extreme cold and in poles it will alternate between 6 months of light and 6 months of darkness..
