Water is boiled in a pan on a stove at sea level. during 10 min of boiling, it is observed that 200 g of water has evaporated. then the rate of heat transfer to the water is 225.7 kj/min 45.1 kj/min 53.5 kj/min 0.84 kj/min 41.8 kj/min

+10 that is always the common denominator

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.
