They really help in the process of Africa's state building, creating commercial networks between parts of the continent, and introducing literacy ( especially on northern part of Africa)
They also controlled the sea route between Asia and Africa and managed to maintain the relationship between Africa and the middle east
Answer:
They can blow from one direction in the morning, and from the opposite direction in the evening, and they are caused from differences in temperature of the land and the ocean.
Explanation:
The coastal breezes are breezes that occur near the coastlines. The general rule for the direction of the wind implies here as well as in any other place in the world, the wind blows from an area with higher air pressure toward an area with lower air pressure. When it comes to the coastal regions, because they have two contrasting landscapes, the wind changes direction during the day.
The land and the water have different properties, with the land heating up much faster and cooling off much faster, while the water heats and cools off slowly. This leads to larger oscillations in the temperature on land and with it larger oscillations in air pressure, while the temperature oscillations in the water are small and with it, the air pressure has much lower oscillation. When the land heats up, the wind blows from the ocean toward land because the air pressure is higher above the water, but when the land is cooler, the wind blows from the land toward the ocean because the air pressure is higher above the land.
Nevertheless, the unifying influence of the monsoons on the Indian subcontinent is quite perceptible. ... These monsoon winds bind the whole country by providing water to set the agricultural activities. Thus, in view of the above the monsoon is considered as a unifying bond for this subcontinent.
Drainage basin - the area of land drained by a river.
Catchment area - the area within the drainage basin.
Watershed - the edge of highland surrounding a drainage basin which marks the boundary between two drainage basins.
Source - the beginning or start of a river.
Confluence - the point at which two rivers or streams join.
Tributary - a stream or smaller river which joins a larger stream or river.
Mouth - the point where the river comes to the end, usually when entering a sea.
Hope this helped :)
