Nebular Theory diagram illustrating the formation of the solar system.

It looks like you've uploaded an image of a worksheet titled "Nebular Theory – Origin of the Solar System", but I currently cannot view or access images directly. However, based on your description and the visible text in your message, I can help you solve the task if you provide the details.

From what I can see:

- The worksheet asks students to explain how the solar system formed using Kant’s nebular hypothesis.
- It mentions that Earth's origin has been debated, but many scientists now accept Kant’s theory (which is actually part of the modern nebular theory).
- Students are asked to place the correct labels in a diagram showing the stages of solar system formation.
- There are six blank boxes, likely representing different stages of the process.

Typical Stages of the Nebular Theory:

Here’s the standard sequence of events in the nebular theory of solar system formation:

1. Interstellar Cloud (Nebula)
A large cloud of gas and dust (mostly hydrogen and helium) begins to collapse under gravity.

2. Gravitational Collapse
The cloud contracts due to gravitational forces, spinning faster as it collapses (conservation of angular momentum).

3. Formation of a Protostar
The center becomes dense and hot, forming a protostar (the early Sun).

4. Accretion Disk Forms
Material around the protostar flattens into a rotating disk (protoplanetary disk), where planets will form.

5. Planetesimals Form
Dust particles collide and stick together, forming larger bodies called planetesimals.

6. Planets Form
Planetesimals grow by accreting more material, eventually forming planets.

How to Fill in the Diagram:

If the worksheet has six boxes arranged in order (from top to bottom or left to right), label them in this sequence:

1. Interstellar cloud (nebula)
2. Gravitational collapse
3. Protostar forms
4. Accretion disk forms
5. Planetesimals form
6. Planets form

You might also be asked to include key terms like:
- *gravitational attraction*
- *spinning disk*
- *accretion*
- *dust and gas*

Example Answer (if labeling):

Assuming the boxes go from left to right or top to bottom:

1. Interstellar Cloud (Nebula)
2. Gravitational Collapse
3. Spinning Disk Forms
4. Accretion of Dust and Gas
5. Planetesimals Form
6. Planets Form

✔ Explanation:
The nebular theory explains that the solar system formed from a giant cloud of gas and dust. Gravity caused the cloud to collapse, forming a spinning disk. The center became the Sun, while material in the disk clumped together to form planets through accretion.

👉 If you can describe the exact layout or provide the missing parts (like the labels available or the diagram structure), I can give a more precise answer tailored to your worksheet.
