Sharecropping varied from state to state, but it was common in many places.

Explanation:

With the Civil War having ended slavery, Southern states still needed cheap labor to work on their farms and so they turned to sharecropping. As most of the South was plantation based, sharecropping took hold in many places.

Sharecropping however varied from state to state based on local laws and norms. In some areas, the sharecroppers were more at a disadvantage due to the laws passed by the state and this led to a lot of them living in abject poverty.

radiative zone

explanation    

radiative zone is the layer of the sun which energy is transferred away from the core by radiation. although, the core is the only part of the sun that produces an appreciable amount of heat through fusion. in fact, 99% of the energy produced by the sun takes place within 24% of the sun's radius.
