- A prism refracts light
- Refracting sunlight / light causes sunlight / light to split into different colors
- Hence, a prism can refract light and split the light into different colors

- A prism can refract light and split the light into different colors
- White light is made of all colors of visible light combined
- So, a prism can refract white light and split the light into all colors of visible light

- The statement "A landslide is when water / gravity rapidly moves rocks / soil downhill especially after a rain storm " is irrelevant

Hence, a prism can refract white light and split the light into all colors of visible light
