It is summer and these grey rocks have turned to a fresh pale green.

This rock turns into the monster that was originally seen on the man's back.

In a week he would have the rock itself turning cartwheels.

"We can tell it by its music, children-the rock has indeed turned to acid."

The rock he faced, which had been yellow-red, turned gray again.

A rock turned under her foot, and she lost her balance.

A hundred and twenty meters up, the rock turned sheer.

She yanked her hand away as if the rock had turned red hot.

Seen in the right light, rocks turn into a kaleidoscope of colors.

Under that titanic violence the rocks turned liquid almost down to the very core of the red world.
