How Lightning Occurs | CBSE 8 | Natural Phenomenon | English

Lightning is a natural phenomenon that can cause large-scale destruction of life and property. We can predict them to a certain extent but not perfectly. It can be explained by using the concept of production of electric charge by rubbing. When a thunderstorm develops, the air currents move upward whereas the water droplets move downward. This movement also causes a separation of positive and negative charges on the clouds. The negative charges accumulate near the lower end of the cloud while the positive charges collect near the upper edge. Also, a positive charge accumulates on the ground as well. As these charges accumulate, it reaches a stage where it is impossible for air (a poor conductor of electricity) to resist the attraction between the positive and negative charges. When these charges meet, they create streaks of light and loud sounds. The charge gets discharged. This discharge can occur between two clouds or between clouds and earth. This causes lightning. #lightning #thunder #lightningandthunder Subscribe to our channel to watch free online lectures For more videos, online classes, 24X7 Doubts solving and Mock tests, Visit Toppr - The better learning app. #BetterLearning on the Toppr app, download now Google Play: http://bit.ly/2vRBqcb App Store: http://apple.co/2vpRAr9 Website: https://www.toppr.com/ Download Doubts on Chat App: Android Play Store: http://bit.ly/2B6w7oy iOS App Store: http://apple.co/2ziAA75 Facebook:   / beingtoppr   Twitter:   / mytoppr   Instagram:   / mytoppr   LinkedIn:   / toppr-com   ****** Related Video ****** Trends In The Modern Periodic Table | Periodic Classification Of Elements | Class 10    • Trends In The Modern Periodic Table |...   Diffusion And Osmosis | Cell-Structure & Function | Biology | Class 9    • Diffusion And Osmosis | Cell-Structur...   Precious Water | Hindi    • Precious Water | Hindi   Transportation in Plants | Biology    • Transportation in Plants | Biology   Cell Membrane/Plasma Membrane | Cell-Structure & Function | Biology | Class 9    • Cell Membrane/Plasma Membrane | Cell-...   Ogives | Maths    • Ogives | Maths   Porifera | Hindi | Diversity In Living Organisms | Biology| Class 9    • Porifera | Hindi | Diversity In Livin...   Homogenous and Heterogeneous Mixture | Is matter around us pure? | Chemistry | Class 9    • Homogenous and Heterogeneous Mixture ...   Cell Division | Hindi | Biology    • Cell Division | Hindi | Biology   Mendeleev's Periodic Table | Periodic Classification Of Elements | Class 10    • Mendeleev's Periodic Table | Periodic...   Structure of Nephron | Hindi | Excretory System | Biology | Class 10    • Structure of Nephron | Hindi |  Excre...   Cell Wall | Cell-Structure & Function | Biology | Class 9    • Cell Wall | Cell-Structure & Function...   Monera | Hindi | Diversity In Living Organisms | Biology | Class 9    • Monera | Hindi | Diversity In Living ...   Lymphatic Circulatory System | Hindi | Biology    • Lymphatic Circulatory System | Hindi ...   Displacement Reactions | Chemistry    • Displacement Reactions | Chemistry   Simple Permanent Tissues | Structural Organisation In Plants | Biology | Class 9    • Simple Permanent Tissues | Structural...   How Lightning Occurs | CBSE 8 | Natural Phenomenon | English    • How Lightning Occurs  | CBSE 8 | Natu...   Electrostatic Force | Physics    • Electrostatic Force | Physics   Pure Substances and Mixtures | Is matter around us pure? | Chemistry | Class 9    • Pure Substances and Mixtures | Is mat...
