Essays on Metallic Hydrogen

Chapter Five

The Snow line which is situated in the disc next to the star like Sun called Hydrae tells astronomies and people on the formation of comets and planets, the origin of the solar system and the factors which determined the composition of comets and planets (Mackey, 2013).

Question Sixteen

Chapter 6 Question six Plate tectonic refers to the sideways movement of big portions of the earth’s crustal plates propelled by convectional currents when heat energy is transferred from the core to the crust, spreading the seafloor along the middle of oceanic ridges. The hot magma cools and forms a ...

Question 1

Jupiter was the first giant planet formed.

Question 2

According to the Nice theory where did the Kuiper belt objects and Oort cloud objects come from?

Kuiper belt objects come from the out edge of Solar System where huge spheres made of rock and ice that circle around Pluto’s orbit. The objects took their name from Gerard Kuiper who suggested that comets may come from the Kuiper belt. This group of planetoids is called Kuiper belt objects (KBO). The first KBO named “1991 QB1” was discovered in 1992. The plant Pluto also belongs to the group of KBO. Some ...

1.Jupiter was the first. Giant lies just beyond the frost line. As the frost line accumulated great amounts of water via evaporation from infalling icy material, it created a zone of lower pressure that increased the speed of orbiting dust particles and halted their motion toward the Sun. As a result , the frost line acted as a barrier whice lead material to accumulate. This excess material coalesced into a huge embryo of around 10 Earth masses, which then began to grow rapidly by swallowing hydrogen from the surrounding disc, reaching 150 Earth masses in only another 1000 years and finally topping out at ...
