Step-by-step explanation:
The geographical location of Southwest Asia makes it positioned at the crossroads of three continents: Africa, Asia, and Europe. This strategic positioning has historically made the region a hub for trade, cultural exchanges, and the spread of religions. Southwest Asia is characterized by its dry or arid type B climate, with the Type H highland climate in the mountainous regions and the more moderate Type C climate along the coastal areas.
Southwest Asia's climate and topography significantly influence the human activities within the realm, which extends from the Atlantic Ocean along the Moroccan coast to the western border of China. The region encompasses diverse geographical features such as mountain ranges, deserts, and coastal areas, but is united by common traits like its predominantly arid climate, the influence of Islam, and the export of petroleum. While hurricanes and typhoons do impact parts of Asia, they are more frequently experienced in areas like Southeast Asia and the surroundings of the Indian Ocean, not typically within Southwest Asia itself.
