What are properties of Soil?

In this article, we will discuss ‘Properties of Soil’ from chapter ‘Soil’ out for Class 7 Science.
 Percolation rate of water in the soil
  • Percolation is the property of absorption of water by soil.
  • If we pour a bottle of water on the floor and another bottle of water in the soil, the water on the floor will flow down but water in the soil will be absorbed.
  • The percolation rate is the amount of water absorbed by any soil at any given time.
  • Formula for calculating percolation rate is,
       Percolation rate (ml/min) = amount of water (ml) / percolation time (min).
  • For example, If 200 ml of water is percolated through the soil sample in 40 min. Calculate the rate of percolation.
Solution – Rate of percolation is = amount of water (ml)/ percolation time (min)
= 200 ml/ 40 min
= 5 ml/ min
Ans- The rate of percolation is 5 ml/ min.
Moisture in soil
  • Moisture is the amount of water present in the soil.
  • During summer, the water content in the soil evaporates and moves up which reflect the sunlight, thus the air above soil seems to shimmer.

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
