It is true that - the Tigris and Euphrates Rivers both flow through Mesopotamia.
Explanation:
Mesopotamia lies at the intersection of three tectonic plates. Both the rivers - The Tigris and Euphrates flow through this region, join to form the Shatt al-Arab and flow into the Persian Gulf. They have many small tributaries which originate from shallow freshwater lakes, swamps and marshes. Due to the rich soil of the rivers, this area developed and an urban civilization emerged in the Uruk period. The people who lived in this river valley created irrigation systems to save water. This was used by farmers to cultivate crops. Plus, the trade via both the rivers flourished which made Sumerian civilization one of the famous among the ancient river valley civilizations.
Answer:
Cyclones are centred on areas of low atmospheric pressure, usually over warm ocean waters near the equator. The warm moist air over the ocean rises from the surface in the upward direction, resulting in the formation of the low-pressure zone over the surface. Air from the surrounding region, with higher pressure, pushes into the low-pressure area.
Cyclones, also known as hurricanes or typhoons, are primarily caused by high ocean temperatures, broad-scale wind systems and clustered thunderstorms, which liberate the heat energy from the ocean surface and transfer it to the cyclone. Ocean temperatures must be higher than 80 degrees Fahrenheit to a depth of at least 150 feet.
