1. **Nebular Hypothesis**: The nebular hypothesis explains that the solar system formed from a giant cloud of gas and dust (solar nebula) that collapsed under its own gravity. As it collapsed, it spun and flattened into a disk, with most of the material accumulating at the center to form the Sun, while the remaining material coalesced into planets, moons, asteroids, and other bodies.
2. **Heliocentric Model**: The heliocentric model of the solar system was first proposed by the astronomer Nicolaus Copernicus in the 16th century. This model posits that the Sun is at the center of the solar system, and the Earth, along with other planets, orbits around it.
3. **Planetesimal vs. Protoplanet**: A planetesimal is a small, solid body that forms from the dust and gas in the solar nebula and is a building block of larger bodies. A protoplanet, on the other hand, is a larger, more advanced stage in planetary formation that has accumulated enough mass to begin gravitating towards a spherical shape and can clear out its orbital path of debris.
4. **Nuclear Fusion**: Nuclear fusion is the process by which hydrogen nuclei combine to form helium, releasing a tremendous amount of energy in the form of light and heat. This process is critical for the Sun as it powers the star, providing the energy that sustains life on Earth and governs solar system dynamics.
5. **Asteroid Belt Location**: The asteroid belt lies between the orbits of Mars and Jupiter.
6. **Source of Long Period Comets**: Long-period comets are believed to originate from the Oort Cloud, a distant spherical shell of icy bodies surrounding the solar system at great distances.
7. **Pluto's Classification**: Pluto is no longer considered a planet because in 2006, the International Astronomical Union (IAU) redefined the criteria for planethood. Pluto does not meet the definition because it has not cleared its orbit of other debris, whereas true planets must dominate their orbital zones.
8. **Geocentric vs. Heliocentric Models**: The geocentric model posits that the Earth is at the center of the universe, with all celestial bodies orbiting around it. The heliocentric model proposes that the Sun is at the center, and the planets, including Earth, orbit around it.
9. **Planets with Retrograde Rotation**: Venus and Uranus have retrograde rotation, meaning they rotate on their axes in the opposite direction to their orbit around the Sun.
10. **Gravitational Force in Nebula**: The force that caused matter in the solar nebula to clump together during the solar system's formation was gravity. As materials condensed and collided due to gravity, denser regions formed, eventually leading to the creation of planets and other solar system bodies.
11. **Evidence for the Big Bang Theory**: Evidence supporting the Big Bang theory includes the observed redshift of galaxies indicating the universe is expanding, the cosmic microwave background radiation, and the abundance of light elements such as hydrogen, helium, and lithium, which align with predictions of nucleosynthesis in the early universe.
12. **Kuiper Belt Location**: The Kuiper Belt is located beyond Neptune, extending from about 30 to 55 astronomical units (AU) from the Sun.
13. **Earth's Differentiation**: Earth's differentiation refers to the process by which the planet's materials, such as metals and silicates, settled into layers based on density during its formation. This process is connected to Earth's early history as it allowed for the formation of a solid crust, a molten outer layer, and the core, laying the groundwork for geological activity and the development of the Earth's structure.
14. **Age Comparison of Earth and Sun**: The Sun is generally older than the Earth. The Sun formed about 4.6 billion years ago, while the Earth formed shortly after, around 4.5 billion years ago.
15. **Role of Collisions and Impacts**: Collisions and impacts were critical in shaping the early solar system as they helped to merge planetesimals into larger protoplanets and played a key role in the differentiation of planetary bodies. These events also contributed to the formation of moons and the distribution of materials within the solar system.
