Slide 1
The Formation of the Solar System Since time immemorial, scientists have worked and conducted numerous researches to find out how the universe came into being. Up to today, there is no single model that can be singled out to explain exactly how the universe formed. However, scientists have agreed on a model that attempts to explain how the universe was formed. Notably, this is termed as the most popular model. The latter is commonly known as the nebular theory hypothesis.

The nebular theory presupposes that the solar system came into being around 4.6 billion years ago. A part of the molecular cloud from the interstellar gas that was full of particles of ice particles, dust particles, rocks, and so forth …show more content…
This part is subjected to very high pressure to an extent that it is always in a solid state despite the fact that there are very high temperatures. The diameter of inner is around 1,000 mi. The outer core is comprised of molten metal and it is has a diameter of around 1,130 mi. There are magnetic currents in the core which are caused by the electric currents that circulate within the outer core. The crust is a hard rock that measures around 390mi in diameter. It is made up of asthenosphere with its base being lithosphere.

Other Terrestrial Planets' Geology and Atmosphere Other terrestrial planets are inclusive of Mercury, Venus, and Mars. Mercury is believed to be the closest planet to the sun with an orbit that has a semi-major axis of 57.9 million kilometers. It takes 87.969 days to complete a single orbit. Mercury lacks real atmosphere and the nearness to the sun makes it very hot. Venus is almost the same size as earth and has a density of 5.2 gm/cm3. It further has intense radiation and very dense atmosphere. Mars is the second smallest planet and its surface gives a red appearance and therefore referred to as the red planet.
