Answer to Question 1

Planetary development in the solar nebula began with the formation of dust grains by condensation. A particle grows by condensation when it adds matter one atom or one molecule at a time, producing a larger body called a planetesimal that contains both rock and metal. A planet grows from accretion and collision of the uniform planetesimals, resulting planet is of homogenous composition. Heat from radioactive decay and planetesimal in-fall causes differentiation, resulting planet has a metal core and low-density crust.

Answer to Question 2

True
