Why have many people in the region relied primary on radio for news and information?

Few adults of any age  say there main source of news is radio. while many americans certainly tune in to radio for emertainment as well as talk radio.

cuz way back then there wasn't such thing as media and people didn't watch much tv back then

Mantle convection is the process that drives plate tectonics. the theory of plate tectonics states that the crust is divided into plates that float on the semi molten mantle below. the circular motion of the magma as it slowly rises and falls or move though convection cells drags the plates along causing them to move. the heat source in the lamp would represent the earth's core. the core is the source of energy that drives convection in the mantle. the lava represents molten magma under the earth's surface. if the lava lamp had floating pieces they would move as the circular motion of the lava in the lamp as it rises and falls would move them along the surface. these floating pieces would represent pieces of the earth's crust.
