The right option is; a. the flow of matter

Rheology is best described as the study of the flow of matter.

Rheology is the branch of physics that studies the deformation and flow of matter (liquid, solid, and gas) but usually in a liquid state. Rheology grouped liquids into two classes which are; Newtonian fluids and Non-Newtonian fluids. The Newtonian fluids are the fluids that conform to Newton's theory, and are said to be perfectly viscous while the non-Newtonian fluids, are the fluids that do not conform to Newton's theory. The Newtonian fluids have a constant ratio between their shear rate and shear stress while the non-Newtonian fluids do not have a constant ratio between their shear rate and shear stress.

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.

true. earthquakes are felt whenever there is a slip around a fault in the rocks below the earth. this reorientation of faults create sesmic waves and is known as earthquake, the severity of which is measured in richter scale. these are more prominent in hilly regions as the rocks usually form faults to balance the pressures on it.
