Answer:
The Coriolis Effect is a very interesting phenomenon that occurs on Earth. It is a force that was studied by Gaspard-Gustave de Coriolis, a mathematician and mechanical engineer of French origin interested in understanding the circulation of winds on the planet.
The Coriolis Effect is the invisible force by which the path of the wind or any moving object is modified due to the rotation of the Earth. As an example, the case of firing a projectile is frequently mentioned. At the time of aiming at the target, this effect must be taken into account since the point of impact will deviate slightly to the right of the direction in which we set our gaze and initially direct the projectile.
As a result of this phenomenon, in the northern hemisphere, in low pressure areas winds blow counterclockwise, and clockwise in high pressure. The opposite happens in the southern hemisphere.

Explanation:There are basically 4 factors that affects a settlement pattern. They are
1. Climatic factor
2. Economic factor
3. Physical factor
4. Traditional factor
Climatic factors includes wet or dry seasons, presence of shelter, and availability of drainage. All of theservice helps to determine if a settlement is well situated.
Physical factors such as shelter or accommodation, soil quality, water supply and the presence of resources can also determine if a location is suitable for establishing a settlement.
Economic factors like nearby markets for buying and selling, local ports for exchange of goods etc are also important before establishing a settlement.
Traditional factors such as rivers, mountains, hills etc that serve as natural defence mechanisms should also be put into consideration
