What are the soil conservation methods? NCERT Class 7 Notes



Erosion of Soil

The erosion of topsoil is referred to as erosion. Deforestation, overgrazing, excessive use of fertilisers or pesticides, precipitation flow, landslides, and floods are all possible causes of erosion.

Mulching - Mulching aids in the retention of moisture in the soil. Mulching is the practise of covering undeveloped area with organic debris such as straw.

Contour Barriers — Contour barriers aid in the prevention of rain-induced erosion. Stone, grass, or dirt connected to the contour forms the contour barrier. To store water, a trench has been dug in front of the dam.

Dams, such as rock dams, can impede the flow of water. As a result, rocks are arranged to create a dam. Dams like these impede water flow. As a result, dirt and soil are not lost.

Terrace Cultivation: In steep places, terrace cultivation is utilised to decrease erosion caused by water flow. To maintain a flat surface for growing crops, the plots are built in terrace designs.

Intercropping: In this method, different crops are planted alternately. Crops mature at various periods. It aids in the prevention of rain-induced erosion.

Contour ploughing is a type of ploughing that is done parallel to the hill slope's outline. It aids in the formation of a natural barrier that keeps water from flowing down a hill.

Shelterbelt: In coastal and dry areas, this strategy is applied. Trees are placed along the field's edge. It aids in the prevention of soil erosion.

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...

What are Noble Gases? Example and noble gases name

What are Noble Gases? Example and noble gases name Noble Gases Noble gases, sometimes known as inert gases or erosions, are part of the modern periodic table's 18th group. This group is made up of the following individuals: Helium is a kind of gas (He) Neon (Ne) Argon is a gas (Ar) Krypton  (Kr) Xenon is a kind of xenon gas (Xe) Radon is a gas that can cause cancer (Rn) Noble gases exist in a gaseous state under typical temperature and pressure conditions. Because all noble gases have stable electronic structures, they have very little chemical reactivity. They are monoatomic gases that do not readily form molecules. 'ns2np6' represents the basic electrical configuration of noble gases. As a result, noble gases' outermost valence shells can be deemed 'complete.' The chemical inertness of the group of 18 elements is due to this. Because of the stability of certain elements, these gases form a group. These stable elements' crusts are totally filled. Regardles...
