Refraction
Your variable changes in a scientific experiment.
Rainbows disappear when the water droplets in the air evaporate or move out of the sunlight's path, causing the sunlight to no longer be refracted and reflected to create the rainbow. Rainbows can also disappear when the angle between the observer, the sun, and the raindrops changes.
Rainbows appear to move across the sky as the angle of sunlight changes and the water droplets in the air refract and reflect the light, creating the colorful arc.

I have no idea the last person said "they move by air" which is not what the question asks
laws and principle governing changes of matter
geologic changes occur suddenly
Changes in load.
Contenintal Drift theory
If David cannot grasp the principle of conservation, he may struggle with understanding that the quantity of a substance remains constant even when its shape or form changes. This concept is important in various scientific fields, such as chemistry and physics, as it helps explain the behavior of matter and energy.
it changes and has stability
