“WEATHERING PRE-VIEW PICTOGRAM PRACTICE”
DIRECTIONS: PLEASE COMPLETE YOUR DRAWINGS FOR EACH NUMBERED TOPIC IN DETAIL. USING
COLOR IS NOT REQUIRED, BUT IS ACCEPTABLE.
1. DRAW A PICTURE SHOWING THE BREAKING DOWN OF ROCK INTO SMALLER PIECES WHICH IS
CALLED WEATHERING.
2. DRAW A PICTURE OF THE MOVEMENT OF SEDIMENT TO ANOTHER LOCATION BY WIND, WATER,
ICE, GRAVITY, ETC…THIS IS CALLED EROSION.
3. DRAW A PICTURE OF THE BREAK DOWN OF ROCK INTO SMALLER PIECES BY PHYSICAL MEANS.
THIS IS CALLED MECHANICAL WEATHERING.
4. DRAW A PICTURE OF ICE WEDGING, AN EXAMPLE OF MECHANICAL WEATHERING. FOLLOW
THESE STEPS.
STEP 1- WATER SEEPS INTO A CRACK DURING WARM WEATHER
STEP 2- WHEN TEMPERATURES DROP, THE WATER FREEZES AND EXPANDS.
STEP 3- THE ICE THEN PUSHES AGAINST THE SIDES OF THE CRACK.
STEP 4- THIS CAUSES THE CRACK TO WIDEN
5. ABRASION IS THE GRINDING AND WEARING AWAY OF ROCK SURFACES THROUGH THE PHYSICAL
ACTION OF OTHER ROCK OR SAND PARTICLES. DRAW A PICTURE OF WATER ABRASION.
FOLLOW THE STEPS BELOW.
STEP 1- ROCKS AND PEBBLES ROLL ALONG THE BOTTOM OF FAST MOVING RIVERS.
STEP 2- THE ROCKS AND PEBBLES BUMP INTO EACH OTHER AND SCRAPE AGAINST EACH OTHER.
STEP 3- WEATHERING OCCURS AND CAUSES THE ROCKS TO BECOME ROUNDED AND SMOOTH.
6. DRAW A PICTURE OF WIND ABRASION, A TYPE OF MECHANICAL WEATHERING.FOLLOW THE
STEPS BELOW.
STEP 1- WIND BLOWS SAND AGAINST ROCK.
STEP 2- THE SAND EVENTUALLY WEARS AWAYTHE ROCK’S SURFACE.
7. DRAW A PICTURE OF GRAVITY ABRASION, A TYPE OF MECHANICAL WEATHERING. FOLLOW
THE STEPS BELOW.
STEP 1- A ROCK BEGINS TO TUMBLE DOWN A MOUNTAINSIDE.
STEP 2- THE ROCK FALLS ON TOP OF ANOTHER ROCK.
STEP 3- ONE ROCK HITS ANOTHER ROCK, AND ANOTHER AND ANOTHER AS THEY TUMBLE
DOWN.
STEP 4- THE ORIGINAL ROCK HAS NOW BEEN BROKEN DOWN INTO SMALL SEDIMENTS AS IT
REACHES THE BOTTOM OF THE MOUNTAIN.
8. DRAW A PICTURE OF A GIGANTIC TREE’S ROOTS BEING STRONG ENOUGH TO BREAK OR CRACK
ROCK. THIS IS AN EXAMPLE OF MECHANICAL WEATHERING.
9. DRAW ANIMALS BURROWING INTO THE SOIL BREAKING DOWN THE SOIL PARTICLES AND
GROUND. THIS IS ANOTHER EXAMPLE OF MECHANICAL WEATHERING.
10. DRAW A PICTURE OF ROCKS BEING BROKEN DOWN AS A RESULT OF CHEMICAL REACTIONS.
THIS IS CALLED CHEMICAL WEATHERING.
11. DRAW A PICTURE OF ACID RAIN HITTING A STATUE WEARING AWAY SOME OF THE FEATURES
ON THAT STATUE. THIS IS AN EXAMPLE OF CHEMICAL WEATHERING.
12. DRAW A PICTURE OF ACID RAIN HITTING TOMBSTONES IN A GRAVEYARD BREAKING DOWN THE
ROCK IN THE TOMBSTONES. THIS IS AN EXAMPLE OF CHEMICAL WEATHERING.
13. DRAW A PICTURE OF AN OLD CAR RUSTING SITTING IN THE DRIVEWAY. THIS IS AN EXAMPLE OF
CHEMICAL WEATHERING DUE TO THE AIR. THE OXYGEN IN THE AIR IS REACTING WITH THE
IRON IN THE CAR, CAUSING THE CAR TO RUST.
14. DRAW A PICTURE OFAN OLD BIKE RUSTING FASTER BECAUSE IT HAS RAINED ON IT FOR MANY
DAYS AS IT SITS OUTSIDE ALONG THE STREET. THIS IS AN EXAMPLE OF CHEMICAL WEATHERING
AND WATER SPEEDS UP THIS KIND OF WEATHERING.
15. DRAW A PICTURE OF A MOUNTAIN PEAK BEING WEATHERED AWAY FASTER THAN THE
BOTTOM PART OF IT. THE MOUNTAIN PEAK IS EXPOSED TO DIFFERENT TYPES OF WEATHER
MORE THAN THE BOTTOM.
16. DRAW A PICTURE OF A MAILBOX RUSTING MORE IN A WARM, HUMID CLIMATE THAN IN A
DRY DESERT CLIMATE. THE WARM, HUMID CLIMATE HAS A FASTER RATE OF CHEMICAL
WEATHERING.
17. DRAW A PICTURE OF A BEACH AREA BEING ERODED FASTER THAN A FOREST. THE FOREST HAS
MORE PLANTS AND TREES THAT PROTECT THE SOIL THAN AN OPEN BEACH AREA.
18. DRAW A PICTURE OF A MARINE ANIMAL’SFOSSIL FOUND NEAR THE TOP OF A MOUNTAIN.
19. DRAW A PICTURE FROM MILLIONS YEARS BEFORE WHEN THAT MOUNTAIN DIDN’T EXIST BUT
THAT AREA WAS ALL OCEAN AND COVERED BY WATER.
20. EXPLAIN WHY A MARINE ANIMAL’S FOSSIL COULD BE DISCOVERED NEAR THE TOP OF A
MOUNTAIN.
21.****BONUS- DRAW A PICTURE OF THE REPEATED FREEZING AND THAWING OF SOIL AND ROCK,
BREAKING DOWN AND CRACKING THE ROCK, CALLED FROST ACTION, A FORM OF MECHANICAL
WEATHERING.
