Once a terrestrial planet had formed from a large number of planetesimals, additional thermal energy from could have melted it and allowed it to differentiate into a dense metallic core and a lower density crust.

radioactive decay

Explanation:

Radioactive decay occurs as the nucleus of a set of unstable isotopes is disrupted as a result of great atomic instability. The nuclear breakdown releases a large amount of thermal energy, which has a very high temperature. An example of radioactive decay occurs when terrestrial planets form through a group of planetesimals. The thermal energy released in this process can even melt this planet.

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.
