‘World’ can also be used attributively, as an adjective, to mean ‘global’, ‘relating to the whole world’, forming usages such as World community. See World
‘World’ distinguishes the entire planet or population from any particular country or region: world affairs are those which pertain not just to one place but to the whole world, and world history is a field of history which examines events from a global perspective. Earth, on the other hand, refers to the planet as a physical entity, and distinguishes it from other planets and physical objects
This natural curiosity has led to the development of advanced tools and skills; humans are the only extant species known to build fires, cook their food, clothe themselves, and use numerous other technologies. Humans are noted for their desire to understand and influence the world around them, seeking to explain and manipulate natural phenomena through science, philosophy, mythology and religion
The earth consists of seven continents listed as follows: North America, South America, Antarctica, Africa, Europe, Asia and Australia; the largest of which is Asia. There are several other methods of determining the continents
In a metaphysical context, World may refer to everything that constitutes reality and the Universe: see World
The World is a proper noun for the planet Earth envisioned from an anthropocentric or human worldview, as a place inhabited by human beings. It is often used to signify the sum of human experience and history, or the ‘human condition’ in general. 67 billion people. The world population is over 6
Since then, Earth’s biosphere has significantly altered the atmosphere and other abiotic conditions on the planet, enabling the proliferation of aerobic organisms as well as the formation of the ozone layer which, together with Earth’s magnetic field, blocks harmful radiation, permitting life on land. Earth is the only place in the universe where life is known to exist at this time. Scientific evidence indicates that the planet formed 4. 54 billion years ago, and life appeared on its surface within a billion years
Like most primates, humans are social by nature. Humans have a marked appreciation for beauty and aesthetics which, combined with the human desire for self-expression, has led to cultural innovations such as art, literature and music. However, humans are particularly adept at utilizing systems of communication for self-expression, the exchange of ideas, and organization. Humans create complex social structures composed of many cooperating and competing groups, from families to nations. Social interactions between humans have established an extremely wide variety of traditions, rituals, ethics, values, social norms, and laws which form the basis of human society
Humans, or human beings, are bipedal primates belonging to the mammalian species Homo sapiens. Humans now inhabit every continent and low Earth orbit, with a total population of over 6. Compared to other species, humans have a highly developed brain capable of abstract reasoning, language, and introspection. DNA evidence indicates that modern humans originated in Africa about 200,000 years ago. This mental capability, combined with an erect body carriage that frees their upper limbs for manipulating objects, has allowed humans to make far greater use of tools than any other species. 7 billion as of March 2008
Earth’s interior remains active, with a thick layer of relatively solid mantle, a liquid outer core that generates a magnetic field, and a solid iron inner core. Earth’s outer surface is divided into several rigid segments, or tectonic plates, that gradually migrate across the surface over periods of many millions of years. About 71% of the surface is covered 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
In English, world may be parsed as rooted in a compound of the obsolete words were, “man”, and eld, “age”; thus, its etymology may be semantically rendered as “age or life of man”
By extension, a ‘world’ may refer to any planet or heavenly body, especially when it is thought of as inhabited
26 solar days. 4° away from the perpendicular to its orbital plane, producing seasonal variations on the planet’s surface with a period of one tropical year . Earth’s only known natural satellite, the Moon, which began orbiting it about 4. 26 times it rotates about its axis. At present, Earth orbits the Sun once for every roughly 365. 53 billion years ago, provides ocean tides, stabilizes the axial tilt and gradually slows the planet’s rotation. Later, asteroid impacts caused significant changes to the surface environment. The Earth’s axis of rotation is tilted 23. A cometary bombardment during the early history of the planet played a role in the formation of the oceans. Earth is impacted upon by other objects in outer space, including the Sun and the Moon. This length of time is a sidereal year, which is equal to 365
‘World’, when qualified, can also refer to a particular domain of human experience
