Question 3

What are the chemical and physical properties of the solar system that any theory of itsorigin must explain?

Accepted Answer

The inner planets have high densities, m

Question 4

What factor caused different planets to form out of different types of material?

Accepted Answer

A) The angular momentum of the forming planet; faster rotating planets lost the lightestelements. 
B) The quantity of dust particles in the solar nebula; more dust caused some planets to containheavier elements. 
C) The variation in temperature throughout the solar nebula; the higher the temperature, thelower the percentage of light elements in the forming planet. 
D) The angular momentum of the solar nebula pushed the heavy elements towards the outerregions of the nebula. 
E) The innate variation of chemical composition of the original nebula; the outer parts of thenebula contained a greater abundance of heavy elements.
