Fresh day Menula, let's solve. 1. Turbines are rotated by the kinetic energy of a moving fluid. This fluid can be: High-pressure steam (produced by heating water using fossil fuels, nuclear reactions, or geothermal energy). Flowing water (from dams or tides). Wind (natural air currents). Hot combustion gases (in gas turbines). 2. The methods described above are used to generate electricity in: Thermal power plants (coal, natural gas, nuclear power plants use steam). Hydroelectric power plants (use flowing water). Wind farms (use wind). Geothermal power plants (use steam from the Earth's heat). 3. Four uses of heat energy are: Cooking and heating (e.g., boiling water, heating homes). Generating electricity (in power plants, heat produces steam to drive turbines). Industrial processes (e.g., melting metals, drying materials, chemical reactions). Sterilization (e.g., killing microorganisms in medical equipment or food). 4. Two natural processes of "scouring" (erosion) due to natural energy are: River erosion (fluvial erosion): The abrasive and hydraulic action of flowing water in rivers, driven by gravity, which scours riverbeds and banks. Glacial erosion: The scouring and plucking action of moving glaciers, driven by gravity, which reshapes valleys and rock surfaces. Send me the next one 📸
