Question

identifying the formation of the solar system
use the drop-down menus to identify the order of these images for the formation of our solar system.

Explanation:

1. The first stage of solar system formation is a large, diffuse cloud of gas and dust (the solar nebula) collapsing under gravity, shown in the middle image.
2. Next, the nebula flattens into a rotating protoplanetary disk, with planetesimals (small rocky bodies) forming in the disk, shown in the left image.
3. Finally, the central protostar ignites to become the Sun, and planetesimals accrete into full planets that settle into stable orbits, shown in the right image.

Answer:

1. Middle image (collapsing solar nebula)
2. Left image (protoplanetary disk with planetesimals)
3. Right image (mature Sun with orbiting planets)

Ordered from first to last: Middle → Left → Right
