Earth

Earth (pronounced /'???/) is the third planet from the Sun and is the major of the terrestrial planets in the Solar System, in both diameter and mass. It is also referred to as the Earth, Planet Earth, and the World, and in several contexts, Gaia and Terra.

Home to millions of species including humans, Earth is the only place in the world where life is known to exist. Scientific evidence indicates that the planet formed 4.54 billion years ago, and life appear on its surface within a billion years. Since then, Earth's biosphere has considerably altered the atmosphere and other abiotic conditions on the planet, enable the proliferation of aerobic organisms as well as the formation of the ozone layer which, jointly with Earth's magnetic field, blocks harmful emission, permitting life on land.

Earth's outer surface is divided into several rigid segments, or tectonic plates, that regularly travel across the surface over periods of many millions of years. About 71% of the surface is enclosed with salt-water oceans, the remainder consisting of continents and islands; liquid water, necessary for all known life, is not known to exist on any other planet's surface. Earth's interior remains active, with a thick layer of comparatively solid mantle, a liquid outer core that generates a magnetic field, and a solid iron inside the core.

Pomegranate

The Pomegranate (Punica granatum) is a fruit-bearing deciduous shrub or tiny tree growing to 5–8 m tall. The pomegranate is native to the region from Afghanistan, Pakistan, and Iran to the Himalayas in northern India and has been enlightened and naturalized over the whole Mediterranean region and the Caucasus since antique times. It is widely cultivated throughout Armenia, Azerbaijan, Iran, and India, the drier parts of Southeast Asia, Peninsular Malaysia, the East Indies, and tropical Africa. Introduced into Latin America and California by Spanish settlers in 1769, pomegranate is now cultivated mostly in the drier parts of California and Arizona for its fruits exploited commercially as juice products in advance in popularity since 2001. In the global functional food industry, pomegranate is included among a novel category of exotic plant sources called super fruits.

In the Northern Hemisphere, the fruit is classically in season from September to January. In the Southern hemisphere, it is in period from March to May.

What is Spamdexing?

Spamdexing has frequent methods, such as repeating unrelated phrases, to control the relevancy or prominence of resources indexed by a search engine, in a manner inconsistent with the idea of the indexing system. Some consider it to be a part of search engine optimization; though there are numerous search engine optimization methods that get better the quality and exterior of the content of web sites and serve content useful to many users. Search engines use a variety of algorithms to end relevancy ranking. Some of these contain determining whether the search term appears in the META keywords tag, others whether the search term appear in the body text or URL of a web page. Many search engines test out for instances of spamdexing and will remove believe pages from their indexes. In addition people working for a search-engine organization can quickly block the results-listing from entire websites that use spamdexing, perhaps alert by user objects of false matches. The rise of spamdexing in the mid-1990s made the majority important search engines of the time less useful.

Custom duty

Customs is a power or agency in a country in charge for collecting customs duties and for controlling the flow of people, animals and goods (including personal effects and hazardous items) in and out of the country. Depending on local legislation and regulations, the import or export of some goods may be controlled or prohibited, and the customs agency enforces this system. The customs agency may be different from the colonization authority, which monitors persons who leave or enter the country, checking for suitable documentation, apprehend people wanted by international search warrants, and impede the entry of others deemed hazardous to the country.
A customs duty is a charge tax on the import of goods or export of goods. In England, customs duties were conventionally part of the customary revenue of the king, and therefore did not need parliamentary consent to be levy, unlike excise duties, land tax, or other impositions.
