Tibetan Plateau Lithograph Answers Why is there less snow around the lake? There is less snow around the lake because although the lake itself is at a high altitude, it is still at a significantly lower altitude than the surrounding snow-covered mountains. As a result, the temperature is warmer near the lake than up high on the mountains so there will be less snow. Additionally, the weather in the area is typically very dry and cold rather than wet and cold. This means there is very low moisture in the air which means that there is less water vapor to become cooled in the atmosphere and become snow. Why is one side of the lake bluer than the other? Looking closely at the picture, it is possible to make out fine lines on the surface of the lake. These lines, which can be seen throughout the entire lake, indicate that the lake is frozen. The lines depict cracks in the ice. There is a difference in the coloration of the lake's surface because the thickness of the ice over the lake varies. The lighter areas of the lake show areas of thicker ice whereas the darker portions of the lake are thinner. View the lithograph (pdf). |
