An ecosystem (also called as environment) is a natural unit consisting of all plants, animals and micro-organisms (biotic factors) in an area functioning together with all of the non-living physical (abiotic) factors of the environment.n ocean is a major body of saline water, and a component of the hydrosphere. Approximately 71% of the Earth's surface (an area of some 362 million square kilometers) is covered by ocean, a continuous body of water that is customarily divided into several principal oceans and smaller seas.
Stucco from the Sardar Rafie Yanehsari building (Shahryari building 1), Hezarjarib District, Behshahr County, Iran. Stucco or render is a material made of aggregates, a binder, and water. Stucco is applied wet and hardens to a very dense solid. It is used as decorative coating for walls and ceilings and as a sculptural and artistic material in architecture. Stucco may be used to cover less visually appealing construction materials such as metal, concrete, cinder block, or clay brick and adobe.
Stucco is a specialized surface, and your preparation of the surface, as well as your coating choice are extremely critical to the success, and long-term durability of your project. Most standard paints and primers are inadequate to seal the pores of a stucco surface, even with multiple coats. You wouldn't want to use latex paint as a primer. Most latex paint in addition to not tolerating the high pH of stucco, often exhibits pinholes in the coating surface due to the porosity of the stucco.
