THE PROCESS BY WHICH WATER, ICE, WIND, OR GRAVITY MOVES WEATHERED PARTICLES OF ROCK AND SOIL.

THE PROCESS THAT CAUSES ROCK TO DECOMPOSE EITHER CHEMICALLY OR PHYSICALLY.

A FORCE PHYSICALLY BREAKING DOWN A ROCK INTO SMALLER PIECES.

THIS ROCK HAS BEEN FORCED APART BECAUSE A PLANT STARTED GROWING IN IT.

RAIN COLLECTED IN THE ROCK, EXPANDED WHEN IT FROZE, & THEN THAWED, CAUSING THE ROCK TO CRACK.

THIS ROCK RUBBED AGAINST OTHER ROCKS, CAUSING PARTS TO BREAK OFF.

A ROCK BEING CHEMICALLY BROKEN DOWN INTO SMALLER PIECES.

DISSOLUTION IS WHEN ROCKS ARE BEING DISSOLVED BY WATER, LIKE THESE ROCKS.

ACID RAIN HAS CAUSED THIS STONE STATUE TO DECOMPOSE & BREAK DOWN QUICKLY.

OXIDATION HAS CAUSED THIS ROCK TO RUST, OR TO BREAK DOWN ALL ITS LAYERS.

THESE ROCKS ARE UNDERGOING OXIDATION WEATHERING IN MINNESOTA.
