Q13. Identify the energy transfer in the completed flow diagram and explain why it is not an
energy transformation.

Q14. Like all models, the flow diagram for the
hydro power plant is simplified. Propose one energy transfer or energy
transformation that could be added to the
flow diagram to make it more accurate.

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.

It has more electrons than an neutral object
