Description**: The project team of the R&D and standardization of exhibits of the Association for Science and Technology in Hefei.
Reference Size (Customized):2.2×2.2×4.0m
Move-in size:About 6
Instructions:
Turn the handwheel and shake the surface water i small ball) through the orbit into the clouds (atmosphere);
Accumulate a certain number of balls, and the rain light starts to rain and the balls fall along the track;
**The balls roll over the biosphere, lithospher, and soil trays, and finally into lakes and oceans;
**The display shows the process and main links of the water cycle.
What to learn:
How is rain formed? Water on the surface of land and sea evaporates into water vapor, which is the water vapor that rises to a certain height and then is cooled and liquefied into small water droplets. These small droplets make up the clouds, and they collide with each other in the clouds to form large droplets. When it was too big for the air to hold, it fell in the clouds and formed rain.
Energy Demand:220v 2000w
Scientific Extension:The formation of rain is a complex process that requires the interaction of multiple meteorological conditions. First, there must be enough water vapor to condense in the air. Water vapor** evaporates from water sources such as oceans, lakes, rivers, etc. When these water vapors rise to the air, the air temperature decreases and the water vapor begins to condense into small water droplets. These small droplets come together to form clouds. Inside the clouds, small water droplets collide with each other and grow in size. When the water droplets are large enough to reach a certain level, they become too heavy to remain in the clouds any longer, so they descend to form rain.
During the descent, small droplets may merge into larger droplets, or form different forms of precipitation such as thundershowers and snow when other meteorological conditions are encountered. In addition, wind is also one of the important factors affecting the formation of rain. The wind can blow clouds apart or gather together, affecting the area and intensity of rainfall.
In conclusion, the formation of rain is a complex process that requires the interaction of multiple meteorological conditions. Through the study and analysis of these conditions, we can better respond to weather changes and protect the safety of life and property in humans and the natural world.
