Read the given paragraph and anwer the following questions.

Cyclones, formidable atmospheric systems, consist of large air masses rotating around a centre of low pressure. Characteristically, their rotation direction differs based on hemisphere—clockwise in the Southern Hemisphere and anticlockwise in the Northern. Essential to their formation are factors like wind speed, direction, temperature, and humidity, which foster the development of these systems characterized by high-speed winds encircling a calm core known as the eye of the storm. Cyclones, vary in nomenclature globally; in the Americas, they are termed 'hurricanes,' while in the Philippines and Japan, 'typhoon' is the preferred term. Interestingly, in Australia, these phenomena are called 'willy-willies.' Despite their different names, the intrinsic violent and rotating nature of these air masses remains a common thread, emphasizing their immense impact on the environment and human activities.
