This solar system consists of four inner rocky planets and four outer gas giant planets as well as an asteroid belt, containing thousands of huge rocks, dwarf planets and comets. Our solar system contains a central star with eight planets, dwarf planets, moons, comets and asteroids.
What are the four key features of our solar system?
Four major features provide clues: (1) The Sun, planets, and large moons generally rotate and orbit in a very organized way. (2) With the exception of Pluto, the planets divide clearly into two groups: terrestrial and jovian. (3) The solar system contains huge numbers of asteroids and comets.
What features of our solar system provide clues to how the solar system formed?
The orbits, spins and motions in the Solar System also provide clues to its formation. As we saw when discussing the night sky, the Solar System has a lot of regularity to it. Most of the planets (and Sun) orbit and spin in the same direction (counterclockwise as viewed from above the Ecliptic).

What are the four major categories of materials in the early solar system?
Composition. The ingredients of the solar nebula fell into 4 categories based on their condensation temperatures: metals, rocks, hydrogen compounds (water, methane, ammonia), and light gasses (hydrogen and helium). Distance of a planet from the Sun determined the temperature and thus the materials which condensed first …
What were the three major components of the solar nebula?
The solar nebula, like most things in the universe, was 98% Hydrogen and Helium, with small amounts of hydrogen compounds (1.4%) and traces of rock and heavy metals (0.6%). All elements heavier than Iron were created in supernova explosions of prior high-mass stars. You just studied 12 terms!
What are the three major stages of planet formation and how do they happen?
Scientists believe that terrestrial planets, like Earth, formed by clumping together from dust and gas into into hot blobs of molten metal and rock several billion years ago. After becoming distinct planets, they went through four stages of formation: Differentiation, Cratering, Flooding and Surface Evolution.

What are the unique features of the earth which are important to life?
Earth is special because it is an ocean planet. Water covers 70% of Earth’s surface. Earth’s atmosphere is made mostly of nitrogen and has plenty of oxygen for us to breathe. The atmosphere also protects us from incoming meteoroids, most of which break up before they can hit the surface.
What are the 3 characteristic of the Earth making it the only livable planet in the solar system?
What makes the Earth habitable? It is the right distance from the Sun, it is protected from harmful solar radiation by its magnetic field, it is kept warm by an insulating atmosphere, and it has the right chemical ingredients for life, including water and carbon.
