Heat In The Core And The Mantle Cause Chemistry. there are three main sources of heat in the deep earth: (1) heat from when the planet formed and accreted, which has not yet been lost; (2) frictional heating, caused by denser core. From the geothermal gradient it is also obvious that the outer core mantle boundary is a big insulater. since these two are separate heat transfer from the outer core to the mantle is also mainly by conduction. for the mantle it is a story of both convection and conduction. i dont think the final answer is known here. as an extra note.
Heat In The Core And The Mantle Cause When the mantle convects, heat is transferred through the mantle by physically moving hot rocks. mantle convection is the result of heat transfer from the core to the base of the lower mantle. as with a pot of soup on a hot stove (figure 3.12), the material near the heat source (the soup at the bottom of the pot) becomes hot and expands, making. By the time you get to the boundary between the mantle and the outer core, which is 1,800 miles (2,900 kilometers) down, the temperature is nearly 5,000 f (2,700 c). then, at the boundary between. This radioactive decay in earth’s crust and mantle continuously adds heat and slows the cooling of the earth. after 4.5 billion years, the inside of the earth is still very hot (in the core, approximately 3,800°c – 6,000°c), and we experience phenomena generated by this heat, including earthquakes, volcanoes, and mountain building. The heat in the outer core results from residual energy from the earth's formative events and the energy generated by decaying radioactive elements. this heat warms the base of the mantle to an estimated 7,230°f. at the mantle crust boundary. the mantle's temperature is an estimated 392°f.

The mantle is the mostly solid bulk of earth’s interior. the mantle lies between earth’s dense, superheated core and its thin outer layer, the crust. the mantle is about 2,900 kilometers (1,802 miles) thick, and makes up a whopping 84 percent of earth’s total volume. as earth began to take shape about 4.5 billion years ago, iron and. Over the past decade, estimates of the heat flow across the core–mantle boundary, or across a chemical boundary layer above it, have generally increased by a factor of 2 to 3. the current total.
