The World

The World is the common name for the planet Earth as seen from a human perspective, considered to be a place where humans live. It is often used to refer to the sum of human experiences and history, or the sum of countries, or the conditions of humanity in general.

In some expressions, the word "world" is used to mean the universe, but there is a significant difference between the two as we see it, and it is not permissible to confuse them. The intended meaning here is the planet Earth that humans inhabit and other living organisms.

The surface of the world consists of water and land, surrounded by layers of the gaseous envelope extending into outer space. Most of the water is in oceans that cover a large area of the Earth's surface. These oceans separate vast masses of solid earth called continents, and smaller masses called islands. Most countries in the world are located within the boundaries of these continents.

The Earth is the only place in the known universe where human life exists. Scientific evidence shows that this planet was formed about 4.6 billion years ago. It appears that life on its surface emerged in the primordial oceans. Through the ages, the Earth's living organisms have been affected by changes in the climate and the oceanic environment. The oceanic environment has had a significant impact on life on Earth, as has the changing climate.

The oceanic environment includes the origin and development of all forms of life on Earth, including plants and animals. Over millions of years, there have been significant changes to the Earth's surface and other conditions unrelated to living organisms, such as volcanoes, earthquakes, plate tectonics, mountain formation, ocean and sea creation, and atmospheric composition. These changes have enabled the spread of light, airborne organisms like pollen and primary cells, in addition to forming the ozone layer.

The Earth's magnetic field works to deflect harmful particles from living organisms and the planet itself into outer space. The ozone layer also absorbs harmful ultraviolet radiation that is damaging to living organisms and humans. The continents were formed as large tectonic plates floating on a molten mantle of the Earth's crust. These massive tectonic plates are in constant motion, causing them to collide with each other, resulting in the formation of mountain ranges like the Himalayas, which exceed 8,000 meters above sea level.

Scientific studies indicate that all continents were once part of a single supercontinent, which later broke apart into large regions and separated from one another. As a result, new continents emerged. This process is still ongoing today, with continents moving away from each other at a rate of millions of years. They also collide and interact with each other in certain areas.

This movement between tectonic plates continues to be active today, resulting in earthquakes where two plates meet.

Usage

The term "world" has been used in Arabic since the beginning of Arab journalism in Lebanon, Egypt, and Algeria. The world distinguishes inhabitants of the planet as a whole or from any specific country or region: global affairs refer not only to one place or one country but to the world.
