Answer:
Step-by-step explanation:
Rain is a natural phenomenon that occurs when water droplets in the atmosphere combine and fall to the ground.
Here's a step-by-step explanation of how rain happens:
1. Evaporation:
It all starts with the process of evaporation. Heat from the sun causes water from various sources like oceans, lakes, and rivers to turn into water vapor and rise into the atmosphere.
2. Condensation:
As the warm, moist air rises, it cools down. When the air temperature drops, the water vapor condenses into tiny water droplets or ice crystals around microscopic particles in the air. These particles can be dust, pollutants, or even salt from the ocean.
3. Cloud formation:
The water droplets and ice crystals combine to form clouds. Clouds are visible masses of suspended water droplets or ice crystals. They can be different shapes and sizes, ranging from fluffy white cumulus clouds to dark and thick cumulonimbus clouds.
4. Precipitation:
Inside the clouds, the water droplets continue to combine and grow larger. When these droplets become too heavy to stay suspended in the air, they fall to the ground as precipitation. Depending on the temperature, precipitation can be in the form of rain, snow, sleet, or hail.
5. Rain formation:
Rain occurs when the temperature in the cloud is above freezing, allowing the water droplets to remain in liquid form. The droplets fall from the cloud and reach the ground as raindrops.
In summary, rain happens when water evaporates, condenses into clouds, and then falls back to the ground as precipitation. It is a complex process influenced by factors such as temperature, humidity, and the presence of particles in the air.
