I have a mixture of rocks,
sand, and water. I pass it
through a screen. What is left
on top of the screen and what
has fallen through the screen?

Respuesta :

The Rocks have remained on top of the screen, while the sand and water have passed through it.
The rocks are on top of the screen while the sand and water have passed through due to the fact that they can pass through the meshing of the screen
