Suppose you have two locations (Stations A and B) that are 200 km apart from each other. Station A is reporting a surface air pressure of 1020 mb while Station B is reporting a surface air pressure of 1012 mb. The pressure gradient between the two cities would be: a. 200mb/8km
b. 8mb/200km
c. 50mb/4km
d. 4mb/50km

Explanation:

what is mb to km please explain

there's multiple reasons why the conquistadors were so successful in colonizing central america, and some of them are:

- they were seen as gods;

at the beginning, the spanish settlers were seen by the natives as gods, and this was mainly due to their white skin, and the way they came with their boats.

- possessed superior weaponry;

the spanish had gunpowder and guns, as well as cannons, while the natives did not had any fire weapons.

- made cleaver alliances;

they used the situation of tribes hating each other, so they made alliances with some of them which served them very well.

- brought diseases;

the native people were not immune to certain diseases the europeans brought with them, so they were dying from seeming harmless things for european standards.
