How will you charge a metal sphere by the process of induction?

A Conducting Sphere Is On Top Of An Insulating Stand. So A Negatively Charged Tube Is Brought Near The Neutral Sphere Then It Forces Electron Movement From The Left To The Right Side Of The Sphere. Once Touched By The Ground, The Electrons Leave The Sphere. When The Tube Is Moved Away, There's An Overall Positive Charge Left On The Sphere.

B) erini just took the test and it is correct

Answer;

hot magma rises and pushes up toward the lithosphere, and as it cools it cycles back down toward the core to be heated again.

explanation; convection currents are the circular pathways taken by a fluid that enhances heat transfer by the process known as convection which occurs in fluids.convection currents transfer heat from one place to another by mass motion of a fluid. earth mantle is in a semi-liquid state and behaves like any other fluid, rising up from the bottom of the mantle after becoming hotter and less dense from heat of the earth's core, as the rock loses heat into the earth's crust it becomes cooler and more dense, then sinking back down to the core, then repeating the cycle.
