Sir i have igko exam on 4 October and i am sure i will get full marks 😀😀😀😜🙏😀😜🙏😀😜 because of your efforts and blessings 🙏💞💞🙏🙏🙏🙏🙏🙏🙏 thank you very much sir apki explanation best than mam also best teaching and learning more about the work bye yyyyyyyy have a great day 🎉🥳🎈🎉🎈🎈🎈🎈🎈🎈
The ozone layer is a protective layer in the Earth's stratosphere that absorbs most of the Sun's harmful ultraviolet (UV) radiation. Without this layer, life on Earth would be at a much higher risk of skin cancer, cataracts, and other health issues due to UV exposure. The ozone layer has been severely depleted in the past due to human-made chemicals, particularly chlorofluorocarbons (CFCs), used in aerosols and refrigerants.
The ionosphere is a region of the Earth's upper atmosphere, located above the mesosphere and extending from about 48 kilometers (30 miles) to hundreds of kilometers above the Earth's surface. It is characterized by a high concentration of ions and free electrons, which are produced by the ionization of molecules and atoms due to the absorption of solar ultraviolet (UV) radiation. The ionosphere is divided into several layers, including the D-layer, E-layer, and F-layer, each of which varies in altitude and ionization levels throughout the day and night. The ionosphere plays a crucial role in radio wave propagation, as it affects the reflection, refraction, and absorption of radio waves. It also influences global positioning systems (GPS), radio communication, and the transmission of signals from space. In summary, the ionosphere is a part of the Earth's upper atmosphere where the presence of ions and free electrons significantly influences the behavior of electromagnetic waves and various communication systems.
Coal is classified into four main types based on carbon content, energy density, and uses. These types are: 1. **Anthracite**: - Highest carbon content (86-97%). - Hard, shiny, and burns with little smoke. - High energy content. - Used mainly for residential and commercial heating. 2. **Bituminous**: - Carbon content between 45-86%. - Most abundant form of coal. - Soft, relatively high energy content. - Used for electricity generation and in steel production (coking coal). 3. **Sub-bituminous**: - Carbon content between 35-45%. - Lower energy content compared to bituminous. - Often used for electricity generation in power plants. 4. **Lignite**: - Lowest carbon content (25-35%). - Soft, brown coal with the lowest energy content. - Used mainly in power generation but less efficient than other types. Each type of coal has different properties and uses based on its carbon content and energy density.
