EARTH`S MATTER THE THREE STATES OF MATTER: SOLID : STONES, ICE. LIQUID: WATER. GASEOUS: AIR, SMOKE SOLID LIQUID GASEOUS
PHYSICAL CHANGES OF THE MATTER SOME EXAMPLES OF PHYSICAL CHANGES ARE CHANGES OF STATE, MOVEMENT AND FRAGMENTATION FOR EXAMPLE LIQUID LAVA BECOMES SOLID WHEN REACHES THE SURFACE THE MOVEMENTS OF AIR AND WATER BREAK UP THE MATTER FOR EXAMPLE, THE MOVEMENT OF WAVES BREAKS UP ROCKS, ANSD WIND ERODES SOFT ROCKS, LIKE LIMESTONES
THE WATER ON EARTH IS CONSTANTLY CHANGING STATE AND PLACE. THE WATER IN OCEANS, RIVERS AND LAKES EVAPORATES AND FORMS CLOUDS. WATER VAPOR IN CLOUDS CONDENSES OR SOLIDIFIES. IT FALLS TO THE GROUND AS RAIN, SNOW OR HAIL.
CHEMICAL CHANGES
SOME CHEMICAL CHANGES OCCUR VERY QUICKLY. SUCH AS PAPER COMBUSTIONS. HOWEVER, CHEMICAL CHANGES IN EARTH`S MATTER OCCUR VERY SLOWLY. W E ONLY SEE THE EFFECTS AFTER HUNDREDS OF YEAR
THE EROSIVE ACTION OF WATER FORM UNDERGROUND CAVES WATER TRANSFORM ROCK MATTER BY DISSOLVING ROCK PARTICLES CREATING A CAVE. CRUDE OIL IS COMPOSE OF REMAINS OF LIVING THINGS. THESE REMAINS WERE BURIED DEEP UNDER THE GROUND THOUSAND OF YEARS AGO.
