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.

Lessons-Worksheets-Question Papers-CBSE Class 2 English CBSE 2nd Class English – One and Many  In this blog, we share the spelling rules used in the concept of  One  and Many. When there is only one of a naming word (noun), it is said to be a  singular noun . When a noun shows more than one, it is said to be in the  plural . We can add  –S, -es, -ves or ies  to show that there is more than one noun.  For example,  we say many birds, four biscuits, six brushes.

Look at these pairs of words: Bus – Buses Brush – Brushes Continue ..... Click here ...

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...
