A
新素材科普知识Our world is full of wonders, making us feel excited and curious. Let's take a look at the following three unusual sights(景象).
1. Colourful Mammatus Clouds
Look up! Sometimes after a storm, you might see strange clouds hanging in the sky. They are called mammatus clouds. These clouds look like big, soft bags hanging downward. They form when cold air falls into warm air full of tiny water drops below storm clouds. Their unusual shape makes them look like something from another planet—colourful and amazing to watch.
2. Red Rain from the Sky
Have you ever heard of rain that is red? Red rain is an unusual sight where rainwater turns pink or red. People once thought it was caused by tiny red
图plants or special light. But now we know it's usually from red dust(灰尘) from faraway deserts mixing with rainwater. This strange rain has been in a few places around the world, making it an amazing sight.
3.
In cold winter, some low-moving rivers or lakes have a special surprise: ice circles. They are round pieces of ice, just like big ice plates. How do they form? Pieces of ice spin(旋转) slowly in the water, and the gentle water smooths them into perfect circles. Only when the temperature and water are just right can we see these perfect natural ice circles.
