im pretty sure its B.
but i know its not A. or D. because those are nonrenewable
but it is possible that it is C.
Because Earth's outer core is liquid and S waves cannot travel trough liquids
I think it is erosion or deposition
South Africa= around 55,000,000 of total population (based on 2015 data)
Nigeria= around <span>185,000,000 of total population (2015 data)
Angola = around </span><span>25,000,000 of total population (2014 data)
Congo= around </span><span>82,000,000 of total population (2015 data)
Given that there's not an high </span>population growth or <span>birth rate or something like that, I'd say Nigeria </span>
