1. Vehicle emissions release nitrogen oxides (NOx) and volatile organic compounds (VOCs) into the air. When sunlight hits these chemicals, they react and form ground-level ozone, a major part of photochemical smog. 2. Smog contains ozone and other pollutants that trap heat in the atmosphere, acting like greenhouse gases. It can also reduce plant growth, which limits how much CO₂ plants can absorb, worsening global warming. 3. *Emission standards for vehicles and factories *Promoting public transport, electric vehicles, and bike lanes. *Use of renewable energy instead of coal and gas. *Smog alerts and no-drive days in highly polluted cities. 4. Smog makes the air hazy, reducing visibility for drivers, pilots, and ships. This increases the risk of accidents, especially in dense traffic or at airports. 5. Smog can be greatly reduced but not completely eliminated unless all pollution. sources (vehicles, industry, burning) are controlled. It’s hard to remove fully in large, crowded, or industrial cities. 6. Smog shares pollutants like sulfur dioxide and nitrogen oxides with acid rain. These pollutants mix with water vapor in the air and fall as acid rain, which harms plants, buildings, and water sources. 7. *Electric and hydrogen-powered vehicles *Air-purifying towers and buildings (e.g., smog-eating surfaces) *Carbon capture and emission filters for factories *AI and sensors to monitor air quality in real time *Urban green walls and roofs to absorb pollutants

1. Governments can attract more FDI by lowering taxes, simplifying business rules, building good infrastructure, ensuring political stability, and creating special economic zones. 2. Tax breaks and subsidies lower business costs, making companies more likely to invest, expand, and create jobs. 3. Lowering interest rates makes borrowing cheaper for businesses, encouraging them to invest in expansion and new projects. 4. Increased government spending on useful projects can drive long-term economic growth, but if uncontrolled, it can also cause inflation and high debt. 5. PPPs allow private companies to help fund and run big government projects, reducing the need for heavy national borrowing.

1. Grain size: Bigger grains = more space = higher porosity and permeability. Sorting: Well-sorted rocks (same-sized grains) have more pores. Compaction: More pressure squeezes grains closer, reducing porosity. Cementation: Minerals filling pores make rocks less permeable. 2. Oil and gas form when dead plants and animals get buried under layers of sediment. Heat and pressure change this material into oil and gas inside porous rocks. Coal forms from swamp plants buried and compacted over millions of years. 3. Found in river valleys, lakes, oceans, deserts, and floodplains. These places collect sediments (sand, mud) over time, which harden into rocks. 4. Weathering breaks rocks into small pieces. Erosion moves these pieces to new places. The pieces settle, pile up, and later turn into new sedimentary rocks. 5. Sandstone is used for building blocks and paving. Limestone is used to make cement and steel. Shale can be used to make bricks and tiles.

1. It is a global agreement made in 1987 to stop using chemicals that damage the ozone layer. Countries agreed to ban harmful substances like CFCs. Because of it, the ozone layer is healing and may fully recover by the 2050s. 2. Arctic: Antartic: Milder ozone loss. Big ozone hole every year. Warmer and less stable weather. Very cold and stable. Happens in March–April. Happens in September–October. 3. Farming: Crops grow poorly, give fewer fruits, and get sick easily. Sea life: Tiny sea plants (phytoplankton) die, hurting fish and coral reefs. 4. New fridges use safer gases like CO₂ and ammonia. Fire systems use safe gases instead of halons. Cleaning agents use water or alcohol-based solutions. Spray cans use compressed air or safe gases. 5. Climate change cools the upper sky, which can slow ozone healing. HFCs (safe for ozone) still warm the planet. Both problems are linked and affect each other.

Finally, someone questions me and also you have wronged me for the final time. 1. Loamy soil is good for farming because it holds water, has nutrients, and is easy to work with. 2. Clay soil can be problematic for plant growth because it often has poor drainage, leading to waterlogging and root rot, and it can compact easily, hindering root penetration.

1. A monopoly can offer stable pricing when demand is predictable, production costs are consistent, and there are no external pressures like government intervention or market disruptions. 2.
