Organic Farming and its benefits Class 9 Science Organic farming is a method of cultivating plants and raising animals in a natural environment. Organic resources are used instead of synthetic ones in this procedure, which helps to maintain soil fertility and ecological balance while also minimising pollution and waste. Benefits of   Organic farming    Organic farming utilises fewer pesticides, lowers soil erosion, reduces nitrate discharge into groundwater and surface water, and recycles animal waste into the farm when compared to standard farming. Consumers will pay more for food, and yields will be lower overall, so these gains will be countered. Organic crops have been reported to have a 25% lower total yield than conventionally grown crops, though this varies widely depending on the type of crop. In the face of climate change and an increasing global population, the challenge for future organic farming is to maintain its ecological benefits, boost yields, and lower prices. Click

How are clouds formed? Class 9 Science Clouds are the white floating balls in the sky that resemble cotton. They are not, however, composed of cotton. Tiny water droplets or ice crystals float in the air, forming clouds. The evaporation process of the Sun causes the air to become moist or humid. The wet air above the Earth's surface is evaporated by the Sun. As the altitude goes higher, the water vapour in the air condenses, and droplets form. The droplets cease travelling when they reach a point in the atmosphere known as the dew point. Snowdrops in the sky clump together to form huge droplets, which are made up of water molecules and are referred to be clouds. The tendency for millions of droplets to join clusters causes them to grow in size. The number of droplets in a cloud is determined by the temperature and pressure of the surrounding environment. These clouds become denser and more saturated as they approach the Earth, resulting in rain. That's how we get snow or hail,
