24. soil investigation By Allah Dad Khan

Soil classification is the process of categorizing soils into groups based on distinct soil properties and characteristics. Soils are classified based on factors such as texture, structure, color, depth, drainage, slope, reaction, and presence of clay, humus or carbonates. Proper soil classification is important for agriculture as it allows farmers to understand the soil type and determine suitable crops and fertilizers needed.

The document discusses various sources of energy, dividing them into conventional and non-conventional sources. Conventional sources include fossil fuels like coal, petroleum and natural gas. These are used in thermal power plants to produce electricity. Hydro power plants use the kinetic energy of flowing water for electricity. Non-conventional sources include solar, wind, biomass, tidal, geothermal and nuclear energy. These provide alternatives to fossil fuels and many are renewable but also have challenges like cost, land use or waste disposal.

Mr.Allah Dad Khan

Tidal energy is a renewable source of energy that harnesses the power of tides. It has several advantages, including being renewable as tides are driven by the gravitational pull of the moon and sun, being a green energy source that doesn't emit greenhouse gases, and having a predictable output. However, tidal energy also has disadvantages such as potentially impacting the environment, only being available when tides are surging for around 10 hours per day so requiring effective energy storage, and being an expensive new technology that is not yet cost-effective.
