Ppt Chapter 1 Section 2 Convection Currents And The Mantle Remember from section 1: the earth’s molten outer core is nearly as hot as the surface of the sun. this heat affects the mantle through heat transfer: the movement of energy from a warmer object to a cooler object. 7 convection currents & the mantle. when you are roasting marshmallows, the stick can heat up and burn your hand when you touch it due to conduction. 8 convection currents & the mantle. 5. convection heat transfer by the movement of a heated fluid; heated particles of fluid begin to flow, transferring heat energy from one part of the fluid to.
Ppt Chapter 1 Section 2 Convection Currents And The Mantle Convection currents are circular currents or movement within a liquid (or gas) due to different densities of the hotter and cooler parts. density is the amount of anything in a certain space; the quantity of a matter in a given area. hot liquids are less dense than cold liquids. currents are a flow of water, air, or any liquid (or gas). Convection current the combination of three things start convection currents moving in the mantle… 1.heating and cooling of a fluid 2.changes in the fluid’s density 3.the force of gravity 17. convection in earth’s mantle the heat from the core creates convection currents that flow through the asthenosphere. Chapter 1 section 2: convection currents and the mantle. chapter 1 section 2: convection currents and the mantle. remember from section 1:. the earth’s molten outer core is nearly as hot as the surface of the sun. this heat affects the mantle through heat transfer: the movement of energy from a warmer object to a cooler object. 858 views. 12. convection in earth’s mantle just like soup in a pot on the stove, earth’s mantle responds to heat. the heat source for the currents in earth’s mantle is heat from earth’s core and from the mantle itself. hot columns of mantle material rise slowly through the asthenosphere as it is heated. at the top of the asthenosphere, the hot material spreads out and pushes the cooler material.

Heat is transferred within the earth's mantle primarily through convection currents. convection currents are caused by differences in temperature within the mantle, causing the denser cooler material to sink and less dense warmer material to rise, creating circulating fluid motions. these convection currents transfer heat from the earth's core outward through the mantle.
