Final answer:
The main components of the Nebular Hypothesis for the origin of the solar system and Earth include the rotating cloud of vapor and dust called the solar nebula, its collapsing under gravity, planetesimal formation, and the heating and differentiation of planets.
Step-by-step explanation:
The main components of the Nebular Hypothesis for the origin of the solar system and Earth include:
- A rotating cloud of vapor and dust called the solar nebula
- The collapse of the solar nebula under its own gravity, leading to the concentration of material at the center
- The vaporization of most solid material in the shrinking nebula due to increasing temperatures
- The formation of planetesimals from condensation in the disk
- The accretion of infalling materials, heating the planets and leading to their differentiation
- The attraction and holding of gas from the solar nebula by the giant planets
- The violent impacts and debris clearing, leaving behind asteroids and cometary remnants
