The International Date Line, established in 1884, passes through the mid-Pacific Ocean and roughly follows a 180 degrees longitude north-south line on the Earth. It is located halfway round the world from the prime meridian—the zero degrees longitude established in Greenwich, England, in 1852.
The International Date Line functions as a “line of demarcation” separating two consecutive calendar dates. When you cross the date line, you become a time traveler of sorts! Cross to the west and it’s one day later; cross back and you’ve “gone back in time."

Since the 1990’s South Africa has moved more toward foreign corporations contributing more economic output. South Africa is greatly impacted by globalization through its import-export trading. During apartheid, <span>industrial firms were prevented by engaging with the global economy, meaning that manufacturers of the country’s economy were used to produce solely for the country’s domestic market. Globalization has enabled many manufacturers to open their markets further, however, it is due to the sheer number of foreign companies in SA that limit the country's ability to be competitive in the global market.</span>
A comet, often known as a filthy snowball, is an ice mass coated with dust and tiny rocky fragments. The comet heats up and emits gases as it approaches the sun, a process known as outgassing. The so-called comet tail results from this.
There are 5 parts of a comet:
- The Nucleus, also known as the core, is a solid mass that is largely formed of ice and dust with a little black biological stuff thrown in. It is just a few kilometers broad.
- A comet's nucleus is surrounded by a spherical envelope of gas called the Coma, which is around a million kilometers large.
- The comet releases hydrogen as it absorbs UV radiation, which escapes the comet's gravity and forms the hydrogen cloud.
- the Dust Tail: The sun's radiation drives dust particles out of the coma. The tail so constantly faces away from the sun. The length of this tail might reach 10 million kilometers.
- the Ion Tail: Some cometary gases become ions when charged solar particles interact with them, creating an ion. The ion track, which is often smaller than the dust path, can be 100 million kilometers long.
