Review of discussion questions:

Elaboration on the planetary differentiation: what are processes of differentiation?

When did these processes occur and what is their product?

All these processes dependent on heat and T distribution. What are sources of heat for accreting and differentiating planetary bodies?

Sources of radiogenic heat?

Importance of size in differentiation process?

Did early meteorites go thud or splat?

Discussion question for next time: What processes can modify meteoritic material after condensation from the nebulaic gases?
