Answer:
(A) The Coriolis force is the force that acts on an object due to the rotation of the earth. The basic rule of this force is that it causes the deflection of wind when it blows from one place to another. The magnitude of this Coriolis force directly depends upon the latitude at which the object is located. This force is maximum at the poles and minimum at the equator.
(B)- Correct answer is Option (2) i.e this force can indicate the wind direction in the northern and southern hemisphere,
When the air in a particular area becomes warm due to heating, then it becomes less dense and rises up. This area forms a low pressure zone. This low pressure zone is filled with the air from the high pressure zone. The wind that blows from the region of high pressure to the region of low pressure does not move in a straight line. Due to the Coriolis force, this wind gets deviate and reaches the low pressure zone.
<u>Thus, this force indicates the direction from which a wind blows in both the southern and the northern hemisphere. In the southern direction it moves in anticlockwise direction, whereas in the northern hemisphere it moves in clockwise direction.</u>
Actually, the increase in life expectancy in Botswana happened in the past (between 2000 and 2010 - in any case, the major reason was the decrease in infant mortality).
In the last years, since 2010 it has fallen again, mostly due to an increase in the occurence of AIDS and violent deaths such as road accidents.
Aliens or illegal immigrants is when Mexicans cross the border illegally and can pay a hefty fine. Close to 11.6 million immigrants in the USA. They can do this for drugs, sexual things that aren't allowed in the USA or maybe just for a better and healthier life. Donald J trump is planning to build a border to prevent these things. (not saying I agree just facts and research I've gathered).
