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, too. Water falls to the ground in the form of snow or hail when large water molecules fall to the ground due to freezing temperatures in an area, rather than raindrops.

The development of clouds is a continuous process that occurs as the air near the Earth's surface receives heat from the Sun, forcing it to rise and create clouds.



Lenticular and stratus clouds are clouds that blow on the edges of a mountain range or topography and are driven to rise into the atmosphere. When air is forced upwards in low-pressure zones, clouds form. Clouds such as Altocumulus, Cirrocumulus, Altostratus, and Stratus are formed as a result of this process.

Why is Hindi Day celebrated on 14 September?

Why is Hindi Day celebrated on 14 September? After independence, the Government of India set a goal to give an ideal form to the mother tongue of the country and set a target for grammar and orthography using the Devanagari script to bring standardization in writing. Subsequently, on September 14, 1949, the Constituent Assembly decided by a vote that Hindi would be the official language of India. To propagate the importance of this decision and to spread Hindi in every region, India is celebrating Hindi Day every year from 1953 to 14 September, at the request of Rashtrabhasha Prachar Samiti, Wardha. Apart from this, 14 September is also the birthday of Rajendra Singh, who worked tirelessly to make Hindi the official language of India. Hindi Day is observed every year on 14 September to mark the importance of the Hindi language in the country. The Hindi language is one of the oldest languages, which derives most of its academic vocabulary from the Sanskrit language written in the Deva

Magnetic and non-magnetic material Class 6 Science

Magnetic and non-magnetic material  Class 6 Science A magnet is a substance that is drawn to certain magnetic materials like iron, cobalt, and nickel. Magnets have the ability to draw iron to them. Natural magnets are rocks that naturally draw iron. Non-magnetic materials include things like wood, rubber, coins, feathers, leather, etc. that are not drawn to iron. Magnet characteristics It pulls magnetic materials, such as iron. The magnet's two ends are referred to as its poles. The magnet's diametrically opposed poles are drawn together. Heating, hammering, or dropping causes it to lose its characteristics. On the basis of properties types of Magnets Temporary magnets are those magnets that are magnetic for only a little duration. Typically, iron, cobalt, or nickel are used to make them. When they are close to the powerful magnet, they act like a magnet. When they are yanked away from the powerful magnet, they stop being magnetic. Permanent magnets are magnets that have magne
