How this related to whats happening in earth

Question 1

What two mechanisms move heat in the earth?

Answer 1

Conduction and convection

Question 2

How does conduction move heat?

Answer 2

Conduction moves heat from the inner core to the outer core

Question 3

How does convection move heat?

Answer 3

Convection moves heat from the outer core to the lower mantle and then to the upper mantle

Question 4

Where else does heat release by conduction and advection?

Answer 4

Heat is released by conduction and advection (especially through volcanoes) through the earth’s crust

Question 5

How does heat move in crust?

Answer 5

Mostly heat advection via magma flow, plus some conduction (via vibration of atomic lattices)

Question 6

How does heat move in the mantle?

Answer 6

Mostly thermochemical convection between a hotter core and colder lithosphere, plus some upward heat advection from asthenosphere and conduction (via vibration of atomic lattices). Mantle is a poor electrical conductor

Question 7

How does heat move in the outer core?

Answer 7

Mostly compositional convection, plus some heat conduction (via electron transfer in iron-rich fluid)

Question 8

How does heat move in inner core?

Answer 8

Mostly heat conduction (via electron transfer in iron-rich crystal matrix), plus some thermal convection

Question 9

What else contributes to these mechanisms?

Answer 9

Thermal radiation may further contribute to and enhance these mechanisms
