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 types of seismic waves are confined at the surface are
- Rayleigh waves
- Love waves
<u>Explanation:</u>
Rayleigh wave are having the motion of retrograde particle which is confined to the vertical plane of the motion. Love wave are having the motion which is transverse which is confined to horizontal plane of the motion. If we talk about other mentioned waves than P waves, S- waves all travel in different pace from slow to fastest. S-waves travel in slow pace whereas p-waves are called the fastest. Disperse waves also travel in a decent speed
The correct answers are:
1. True;
In the European Union there's members from all parts of the continent, including Central and Eastern Europe.
2. False;
Northern Ireland, even though is located on the island of Ireland, it is actually a part of the United Kingdom of Great Britain and Northern Ireland.
