Step-by-step solution for: Formation of Solar System Storyboard by e436a306
The image you provided illustrates the formation of the solar system over billions of years. Below is a detailed explanation of each step in the process, as depicted in the image:
---
- Description: A cloud of gas and dust, known as a molecular cloud, existed in space.
- Key Event: Due to gravitational forces, this cloud began to collapse under its own weight.
- Result: The collapsing cloud formed a rotating disk of material, which would eventually become the solar nebula.
---
- Description: As the cloud collapsed further, it became denser and hotter at the center.
- Key Event: The increasing density and temperature caused hydrogen atoms to fuse into helium through nuclear fusion.
- Result: This fusion reaction released a massive amount of energy, marking the birth of the Sun.
---
- Description: After the Sun formed, the remaining swirling material around it continued to rotate in a disk-like structure.
- Key Event: This disk, called the protoplanetary disk, contained dust, gas, and other particles that would eventually form the planets and other celestial bodies.
- Result: The solar nebula was now a swirling disk of material orbiting the newly formed Sun.
---
- Description: The gravity of the Sun attracted more matter from the surrounding disk.
- Key Event: Hydrogen atoms combined to form helium through nuclear fusion, releasing energy.
- Result: This process stabilized the Sun and allowed it to shine brightly, providing the energy needed for the rest of the solar system to evolve.
---
- Description: Material in the outer regions of the protoplanetary disk began to clump together due to gravitational attraction.
- Key Event: Larger clumps grew into planets, moons, and dwarf planets. Smaller remnants became asteroids, comets, and smaller moons.
- Result: The inner part of the disk formed rocky planets (like Earth), while the outer part formed gas giants (like Jupiter).
---
- Description: Over time, the solar system reached its current state.
- Key Event: All the processes described above resulted in the formation of the Sun, planets, moons, asteroids, comets, and other celestial bodies.
- Result: The solar system as we know it today, with the Sun at the center and planets orbiting around it, was established.
---
1. Initial Cloud: A molecular cloud of gas and dust collapses due to gravity.
2. Formation of the Sun: The densest part of the cloud becomes extremely hot and begins nuclear fusion, forming the Sun.
3. Protoplanetary Disk: The remaining material forms a rotating disk around the Sun.
4. Accretion and Fusion: The Sun stabilizes through nuclear fusion, attracting more matter.
5. Planet Formation: Clumping of material in the disk leads to the formation of planets, moons, and other bodies.
6. Final Solar System: The solar system reaches its current configuration.

The image depicts the formation of the solar system over billions of years, starting from a molecular cloud and ending with the modern solar system. The key steps include:
1. Collapse of a molecular cloud.
2. Formation of the Sun through nuclear fusion.
3. Creation of a protoplanetary disk.
4. Accretion of matter leading to planet formation.
5. Evolution into the current solar system.

Step 1: Formation of the Solar Nebula (13.8 - 4.6 Billion Years Ago)
- Description: A cloud of gas and dust, known as a molecular cloud, existed in space.
- Key Event: Due to gravitational forces, this cloud began to collapse under its own weight.
- Result: The collapsing cloud formed a rotating disk of material, which would eventually become the solar nebula.
---
Step 2: Formation of the Sun (4.6 Billion Years Ago)
- Description: As the cloud collapsed further, it became denser and hotter at the center.
- Key Event: The increasing density and temperature caused hydrogen atoms to fuse into helium through nuclear fusion.
- Result: This fusion reaction released a massive amount of energy, marking the birth of the Sun.
---
Step 3: Solar Nebula and Protoplanetary Disk (4.6 Billion Years Ago)
- Description: After the Sun formed, the remaining swirling material around it continued to rotate in a disk-like structure.
- Key Event: This disk, called the protoplanetary disk, contained dust, gas, and other particles that would eventually form the planets and other celestial bodies.
- Result: The solar nebula was now a swirling disk of material orbiting the newly formed Sun.
---
Step 4: Accretion of Matter (4.5 Billion Years Ago)
- Description: The gravity of the Sun attracted more matter from the surrounding disk.
- Key Event: Hydrogen atoms combined to form helium through nuclear fusion, releasing energy.
- Result: This process stabilized the Sun and allowed it to shine brightly, providing the energy needed for the rest of the solar system to evolve.
---
Step 5: Formation of Planets and Other Bodies (4 Billion Years Ago)
- Description: Material in the outer regions of the protoplanetary disk began to clump together due to gravitational attraction.
- Key Event: Larger clumps grew into planets, moons, and dwarf planets. Smaller remnants became asteroids, comets, and smaller moons.
- Result: The inner part of the disk formed rocky planets (like Earth), while the outer part formed gas giants (like Jupiter).
---
Step 6: Modern Solar System (Today)
- Description: Over time, the solar system reached its current state.
- Key Event: All the processes described above resulted in the formation of the Sun, planets, moons, asteroids, comets, and other celestial bodies.
- Result: The solar system as we know it today, with the Sun at the center and planets orbiting around it, was established.
