On February 2, 2021, my father and I found a lot of problems within 10 minutes in the Geological Museum, especially the errors in the exhibition hall on the 2nd floor: the solar system model on the wall on the entrance of the exhibition hall on the 1st and 2nd floors is very unrigorous, and Mars is bigger than Venus; 2, Mercury color is not correct, Mercury should be gray yellow white (the sun makes it yellow white), the Earth is slightly blue; 3, Mars Arctic no ice sheet; 4, the Earth's oblique angle is wrong, and the Earth's proportion is not scientific; 5, Jupiter, Uranus, Neptune have no rings. 6, the mainland drift said five continents and four oceans, even if the times are limited, but the expression is not rigorous, lack of scientific spirit. I personally feel that the Ningxia Geological Museum faces the whole Ningxia, which is a window of geological sciences in Ningxia. It is extremely important and educational. If it is not rigorous in science or has mistakes, it will mislead everyone, especially students. Chen Yuming is 8 years old
