Tina had a mixture of sand, gravel, pebbles, and clay. she placed the mixture on a fine wire screen. then she shook the screen. what will fall through the screen? a) clay b) gravel c) pebbles d) sand

The particles that would be able to be shifted through the screen would be the finest or smallest particles.

The correct answer would be D. Sand.

Because sand has the finest particles, it would be able to be sifted through the screen. Clay has high density and would just goop up on the surface of the screen, unable to go through. Both gravel and pebbles are too large to be sifted.

Hope this helps! :)
