Question

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

Explanation:

To determine the order of solar system formation, we analyze the stages:

1. First Stage (Middle Image): A nebula (cloud of gas/dust) collapses under gravity. The middle image shows a nebula with matter clumping, representing the initial nebular collapse.
2. Second Stage (Left Image): A protostar forms at the center, and a protoplanetary disk (with planetesimals) develops. The left image has a central star and a disk with planetesimals.
3. Third Stage (Right Image): Planets orbit the formed sun, with a stable solar system. The right image shows the sun and orbiting planets (like Saturn, Jupiter) with asteroid belts.

So the order (from first to last) is:

1. Middle image (nebular collapse)
2. Left image (protostar + protoplanetary disk)
3. Right image (mature solar system)

If we label the images as Image 1 (left), Image 2 (middle), Image 3 (right), the order is Image 2 → Image 1 → Image 3.
