Is responsible for the development of earth's crust, mantle, and core. the core is responsible for creating earth's magnetic field. 2. debris that orbited earth after a giant impact accreted and contributed to the formation of the . 3. created an atmosphere that ultimately enabled the development of higher life forms. 4. without , elements with a higher atomic number than iron would not exist. 5. is the process by which the planets formed from material in the solar nebula and the process by which the moon formed from impact debris?

1. Density Differentiation is responsible for the distinct layers of the Earth. Denser materials (Iron, Nickel, and other elements) sunk deeper and formed the core while less dense materials(aluminum, calcium, oxygen, silicon, etc.) formed the crust and mantle.    

2. The debris which were orbiting the Earth from an impact accreted together to form the Moon.

3. Volcanic Eruptions which spewed large amounts of gasses (carbon dioxide, nitrogen, and other gasses) were attributed for the creation of the first atmosphere here on Earth. This process is also known as Volcanic Outgassing. 

4.  All elements which are heavier than Iron (Fe) are formed from Supernova explosions.

5. The process involved in the formation of planets and the moon from materials in the solar nebula and debris is called Accretion.

The answer is cultural
