Explanation:
The world is the planet Earth and all life on it, including human civilization.[1] In a philosophical context, the "world" is the whole of the physical Universe, or an ontological world (the "world" of an individual). In a theological context, the world is the material or the profane sphere, as opposed to the celestial, spiritual, transcendent or sacred spheres. "End of the world" scenarios refer to the end of human history, often in religious contexts.
The history of the world is commonly understood as spanning the major geopolitical developments of about five millennia, from the first civilizations to the present. In terms such as world religion, world language, world government, and world war, the term world suggests an international or intercontinental scope without necessarily implying participation of every part of the world.
The world population is the sum of all human populations at any time; similarly, the world economy is the sum of the economies of all societies or countries, especially in the context of globalization. Terms such as "world championship", "gross world product", and "world flags" imply the sum or combination of all sovereign states.
The corresponding word in Latin is mundus, literally "clean, elegant", itself a loan translation of Greek cosmos "orderly arrangement." While the Germanic word thus reflects a mythological notion of a "domain of Man" (compare Midgard), presumably as opposed to the divine sphere on the one hand and the chthonic sphere of the underworld on the other, the Greco-Latin term expresses a notion of creation as an act of establishing order out of chaos.
"World" distinguishes the entire planet or population from any particular country or region: world affairs pertain not just to one place but to the whole world, and world history is a field of history that examines events from a global (rather than a national or a regional) perspective. Earth, on the other hand, refers to the planet as a physical entity, and distinguishes it from other planets and physical objects.
"World" was also classically used to mean the material universe, or the cosmos: "The worlde is an apte frame of heauen and earthe, and all other naturall thinges contained in them."[4] The earth was often described as "the center of the world".[5]
The term can also be used attributively, to mean "global", or "relating to the whole world", forming usages such as world community or world canonical texts.[6]
By extension, a world may refer to any planet or heavenly body, especially when it is thought of as inhabited, especially in the context of science fiction or futurology.
World, in its original sense, when qualified, can also refer to a particular domain of human experience.
Answer:
The World - The Planet We Live In
The third planet Earth is our world. It is our home. Yet we know so little about it. The land masses, the water bodies, the atmosphere, and the different life forms and species in our world make it intriguing, complex and intricate. It is so beautiful and yet so complicated. No one in the world can explain our world to satisfaction because it is also a place of mysterious and systems working together in ways we cannot fully comprehend. The planet earth is one of the nine planets in the solar system and the only known planet to harbor life and the home of human beings. About 71 percent of the earth’s surface is covered with water and the rest is land, mostly in the form of continents that rise above the oceans.
The earth has a unique characteristic that is suited to supporting life. It is neither too hot like planet Mercury, the closest planet to the Sun, nor too cold like planet Mars.
Earth’s Features
The natural features of the earth’s land surfaces are called landforms. These features are used to describe and help people to locate specific places.
Landforms are defined as the natural physical features found on the surface of the earth. Landforms are created as a result of the various forces of nature such as wind, water and ice and also by the movement of the earth’s tectonic plates. Due to these actions, the soil gets eroded and deposited somewhere far from the site of erosion, thus leads to the formation of different landforms. Some landforms are created in a matter of few hours; others take millions of years to appear.
Mountains: Mountains are areas, which are higher than the surrounding areas and are characterized by a peak, e.g. The Himalayas. Surprisingly, they are more frequently present in the oceans than in land. A mountain is steeper than a hill. Mountains are formed due the tectonic movement such as an earthquake or a volcanic eruption. A few are resulted due to erosion of the surrounding areas by the action of wind, water or ice.
Plateaus: Plateaus are large highland flat areas separated from the surrounding areas by a steep slope, e.g. The Tibetan plateau. Plateaus are formed due to various actions such as collision of the earth’s tectonic plates, uplift of the earth’s crust by the action of magma; some are resulted due to the lava flow from the volcanic eruption.
Islands: Islands are areas that are completely surrounded by water, e.g. The Hawaiian Islands. Islands are formed either as a result of the volcanic eruption or due to the presence of hot spots on the lithosphere.
Plains: Plains are flat areas or low relief areas on the earth’s surface, e.g. prairies, steppes. Plains are formed due to the sedimentation of the eroded soil from the hills and mountains or due to the flowing lava deposited by the agents of wind, water and ice.
Valleys: Valleys are flat areas of land between the hills or mountains, e.g. The California Central Valley. Mostly they are formed by the actions of rivers and glaciers.
Deserts: Deserts are very dry lands with little or no rainfall, for example, The Sahara desert. Mostly deserts are formed in rain shadow areas, which are leeward of a mountain range with respect to the wind direction. Thus, the mountains block the passage of wind resulting in little or sometimes no rain.
Loess: Loess are deposits of silt and with a little amount of sand and clay. Many a times wind action is responsible for formation of loess; however sometimes glacial activity can also form loess.
Rivers: Rivers are natural flowing stream of freshwater, e.g. The Nile. They mostly flow towards lakes or oceans but sometimes they dried up without reaching another water body. River water is collected from the surface water runoffs, groundwater water recharge and sometimes from the water reservoirs such as glaciers. Landforms definitely play an important role in the formation of rivers.
Oceans: Oceans are the biggest form of water and are saline, such as The Pacific Ocean. Oceans of the world covers around 71% of the earth’s surface and control the weather and climate of the earth’s surface.
Glaciers: Glaciers are huge slow moving body of ice. Glaciers are formed due to the compaction of snow layers and moves with respect to gravity and pressure. Mainly there are two types of glaciers- Alpine glaciers, which are formed in high mountains and Continental glaciers, which are formed in cold Polar Regions.
Continents
Land surface of the earth was divided into seven landmasses called continents. Land surface of the earth was divided into seven landmasses called continents. A continent is defined as a large unbroken land mass completely surrounded by water, although in some cases continents are (or were in part) connected by land bridges. The seven continents are North America, South America, Europe, Asia, Africa, Australia, and Antarctica. The islands in the Pacific are often called Oceania.
