Lesson 8.5: The Earth's Internal Heat Flashcards
1
Q
it is the internal heat energy accumulated by dissipation in a planet during its first few million years of evolution
A
primordial heat
2
Q
the heat generated by the decay of radioactive isotopes of elements
A
radiogenic heat
3
Q
it is the process by which heat energy is transmitted through collisions between neighboring atoms or molecules
A
conduction
4
Q
a thermally driven process where heating at depth causes material to expand and becomes less dense, causing it to rise while being replaced by complimentary cool material that sinks
A
convection
5
Q
