Notes:
Following the sun, Alpha Centauri is the closest star to Earth, located approximately 4.367 light years away. It’s a star system consisting of three stars: Alpha Centauri A, Alpha Centauri B, and Proxima Centauri.

Notes:
Eastern European and Balkan countries experience the highest rates of air pollution in the European Union. Particularly, Bosnia and Herzegovina, Bulgaria, Albania, and Ukraine have the most significant mortality rates attributed to air pollution in the region. These countries also record the highest average annual levels of city air pollution, with Bosnia and Herzegovina being the most affected.

Notes:
The word ‘planet’ comes from the ancient Greek ἀστήρ πλανήτης (astēr planētēs), meaning “wandering star”. The large number of stars observed in the heavens were classified into fixed stars and wandering stars. Fixed stars were those with respect to which the movement of the celestial bodies were measured. Wandering stars were those whose relative distances with respect to the fixed stars keep changing. Mars, Venus, Jupiter, Mercury and Saturn belonged to the latter category. Among these, Jupiter was known as Bright Wandering Star.

Ethiopia was in the past known as Abyssinia. The switch to the name Ethiopia happened around the 4th century during the reign of King Ezana, who adopted the name as part of his conversion efforts to Christianity. Historical records suggest that the term ‘Ethiopia’ was derived from the Greek term ‘Aithiops’, meaning ‘burnt face’ or ‘burnt complexion’ – a clear reference to the physical appearance of the country’s inhabitants.

Notes:
China is the world’s leading producer of synthetic industrial diamonds. Industrial diamonds can be used in cutting, drilling, grinding, and polishing.

Notes:
The correct reason for sprinkling salt on icy roads is that “the salt lowers the freezing point of water.” This process is known as freezing point depression. When salt (sodium chloride) is added to ice, it disrupts the formation of ice crystals, causing the ice to melt at lower temperatures. This is why salt is commonly used in winter road maintenance. it helps to keep roads safer by preventing ice formation. In fact, salt can lower the freezing point of water to about -9.5°C (15°F) when used in sufficient quantities.

Notes:
Pemba Island is famous for the cultivation of cloves. The island is part of the Zanzibar Archipelago in Tanzania, which is located in the Indian Ocean. Pemba is known as the “clove island” because it is the world’s main exporter of cloves. The island has 3.5 million clove trees, which is the largest concentration of clove trees in Zanzibar. Pemba’s growing conditions are better than those on Unguja island.  Zanzibar’s main industries are spices, raffia, and tourism. The islands produce cloves, nutmeg, cinnamon, and black pepper. The Zanzibar Archipelago, along with Tanzania’s Mafia Island, are sometimes called the “Spice Islands”.

Notes:
Ranching is the practice of raising livestock on large tracts of land. Ranchers typically raise grazing animals such as cattle and sheep, but some also raise bison, elk, emus, ostriches, and alpacas. Ranches are usually found in parts of the grasslands where rainfall is low and food crops do not grow very well. Ranching is the dominant land use in much of the American West. Ranching can be highly profitable. The ranching and livestock industry is growing faster than any other agricultural sector in the world. In Africa, most ranches are wildlife ranches. Wildlife ranches, also known as game ranches, maintain healthy populations of species such as rhinoceros, elephant, leopard, and antelope. People pay a fee to hunt these animals on the ranch. Wildlife ranches also appeal to ecotourists.

Notes:
Gulf of Thailand is the part of the South China Sea. It is also known as the Gulf of Siam. It is a marginal water body in the western Pacific Ocean. It is surrounded by Cambodia and Vietnam in the northeast, and by Thailand in the rest part.
