An atom of an element that has the same atomic number but additional neutrons is called an isotope. This isotopes are usually........

radioactive

unstable

changing to a more stable form

all of the above

The basic steps of planet formation(in order) would be.......

geological activity on the surface, condensation and collapse of dust and gases in space, condensation and collapse of dust and gases in space, accumulation of additional material due to collesions and gravitational attraction(accretion)

geological activity on the surface, condensation and collapse of dust and gases in space, accumulation of additional material due to collesions and gravitational attraction(accretion),repeated heating and melting due to radioactivity which causes the planet to develop layers(differentiation)

How does the density of materials in the Earth affect how seismic waves move through them?

The density does not affect how the waves move

Seismic waves move faster through more dense material

All seismic waves will move through all materials at the same speed no matter of their density

Seismic waves move slower through more dense materials

___________is the process of separating out different materials of a planetary body as a consequence of their physical or chemical behavior, where the body develops into distinct layers based on composition; the denser materials of a planet sink to the center, while less dense materials rise to the surface.

accretion

gravitational attraction
