- Artificial jewelry, usually made of less expensive metals is often plated with a thin layer of a precious metal like gold and silver to make it more lustrous, appealing but cheaper.
- Many industrial applications use electroplating to create a protective barrier on a metal substrate. The protective barrier in this case prevents tarnishing and gives a glossy appearance. Eg: Chromium plating is done on car spare parts, taps, wheel rims etc. Chromium is very expensive and the whole part cannot be made of chromium. So, it is coated with chromium to give it a shiny appearance.
- Tinning (electroplating of tin) is a very cost-effective electroplating solution. Tin is relatively cheaper and is used for electroplating electronic components, hardware products, fasteners, screws, nuts, bolts and food cans. If food is stored in iron cans, it would tend to get spoilt over a period of time. But, when iron is electroplated with tin, it prevents the food from getting spoilt. Tinning offers resistance against corrosion

O Horizon - The top, organic layer of soil, made up mostly of leaf litter and humus (decomposed organic matter). A Horizon - The layer called topsoil; it is found below the O horizon and above the E horizon. Seeds germinate and plant roots grow in this dark-colored layer. If the top layer of soil is exposed, then it will gradually expose the lower layer of soil, which is hard and rocky in nature. This type of soil is less fertile as it contains less humus. Continued soil erosion will make the land barren or infertile.
