0:44
DID YOU EVER STOP TO THINK THAT THE WHOLE WORLD IS COVERED WITH ROCKS AND EVERY ROCK USED TO BE DIFFERENT? WHEN YOU'RE LOOKING AT A ROCK, YOU'RE LOOKING AT HISTORY. Man: CAREFUL. (<i> crash</i> )
1:01
SEE ALL OF THE ROCKS IN THE WORLD USED TO BE MELTED ROCKS. WHAT WE CALL MOLTEN ROCKS. MOLTEN-- LIKE THIS MOLTEN ROCK IN HERE. CAN YOU SEE THE BUBBLE ON TOP? THAT'S FROM THE HEAT. IT'S JUST LIKE THE ROCKS THAT COME OUT OF VOLCANOES. (<i> explosion</i> ) ROCKS LIKE THIS. ROCKS LIKE THIS. ROCKS LIKE THESE. SEE THESE PITS? THEY WERE FORMED BY BUBBLES IN LIQUID ROCK THAT CAME OUT OF A VOLCANO. SOMETIMES VOLCANIC ROCK WILL COME ONTO THE EARTH'S SURFACE. NOW, WHEN THESE ROCKS GET ON THE EARTH'S SURFACE
1:38
THEY PUSH OTHER ROCKS DOWN. IT PUSHES DOWN ON THE LAYERS BELOW. PUSH THE OLD ROCKS DOWN. PUSH THEM DOWN AND THEY'LL SQUEEZE TOGETHER AND SWIRL AROUND. WHEN THEY BLEND, THEY FORM A NEW ROCK. LIKE THE MINERALS THAT ARE SWIRLED IN THIS PIECE OF MARBLE. WIND AND RAIN MOVING OVER THE EARTH'S SURFACE BREAK ROCK DOWN INTO SAND. SOMETIMES WATER WILL FLOW THROUGH DUST AND SAND MIX THEM TOGETHER IT'LL DRY OUT AGAIN AND TURN BACK INTO ROCK LIKE THESE. GOOD THING I HAVE MY SAFETY GLASSES ON.
2:14
THIS PROCESS WHERE ROCKS ARE FORMED, BROKEN DOWN, REFORMED AS THEY COME OUT OF THE MOLTEN EARTH AND TURN BACK INTO DUST AND ROCKS AGAIN HAS BEEN GOING ON SINCE THE WORLD WAS FORMED-- BILLIONS, BILLIONS OF... BILLIONS OF YEARS AGO. ROCKS... ROCK! ROCKS ROCK! <i> AND NOW, SANDY STONE.</i> ♪ OOH, I LOVE YOU, LAVA BABY... ♪ <i> HE'LL ROLL RIGHT</i> <i> OVER YOUR HEART...</i> ♪ IT MAKES ME HURT WHEN YOU CALL ME DIRT... ♪ <i> BECAUSE HE'S GRITTY.</i> ♪ COULD YOU BE... ♪
2:47
♪ THE MOST BEAUTIFUL GRANITE ON THE PLANET? ♪ <i> ORDER NOW.</i> THIS IS DIRT-- BROKEN DOWN ROCKS AND WHEN MICROSCOPIC LIVING THINGS GET IN IT IT CAN TURN INTO RICH, DARK SOIL THAT PLANTS CAN GROW IN. SOIL COMES FROM DIRT, WHICH COMES FROM ROCKS. IT'S AN IDEA AS OLD AS...
3:13
AS YOU CAN SEE, THERE ARE NO MIGHTY ROCKS HERE NOW. IT'S ALL BEEN REDUCED TO EENIE, TEENY, TINY BITS OF SAND REDUCED BY THE POUNDING SURF THE MERCILESS STORMS, WEAKENED BY THE SUN BUT MOSTLY BY THE POUNDING, POUNDING... Bill: SO THE SAND HAS BEEN POUNDED FROM SOLID ROCK. THAT ROCK WAS ONCE LIQUID, MOLTEN ROCK. HEY, HEY, I'M NOT FINISHED. SO WHAT CAN THE GOVERNMENT DO ABOUT THIS POUNDING POUNDING, POUNDING? IN THE FINAL ANALYSIS, NOTHING. WE'RE TALKING ABOUT THOUSANDS OF YEARS.
3:46
DIFFERENT ROCKS ARE FORMED DIFFERENTLY. ALL THE MATERIAL IN THIS SANDSTONE ONCE BELONGED TO OTHER ROCKS. THAT ROCKS. SCIENTISTS LIKE TO THINK OF THREE TYPES OF ROCK.
3:59
NOW, THE FIRST TYPE YOU MIGHT CALL IGNEOUS ROCK. IGNEOUS ROCK-- WHICH COMES FROM THE WORD FIRE. YOU KNOW HOW YOU IGNITE THE CANDLE AND YOU HAVE IGNEOUS ROCKS. IGNEOUS, IGNITE-- FROM THE WORD FOR FIRE. SO SEE HOW THE CANDLE WAX DRIPS DOWN THE OUTSIDE OF THE CANDLE. WELL, IGNEOUS ROCKS ARE OFTEN FORMED WHEN HOT LAVA DRIPS DOWN THE OUTSIDES OF VOLCANOES AND IT COOLS TO FORM ROCKS LIKE THIS GRANITE. SEE? THE NEXT TYPE OF ROCK, CALLED SEDIMENTARY ROCK... NOW, SEDIMENT, THAT'S SILT.
4:34
MUD, GOOP IN RIVERS. SO IF YOU HAVE A RIVER AND IT'S WASHING SAND, MUD OR SILT-- SEDIMENT-- DOWNSTREAM WELL, EVENTUALLY THE RIVER MAY DRY UP OR DRAIN AWAY LEAVING THE SEDIMENT-- THE SAND, SILT, OR MUD. NOW, THIS SAND WOULD BE HEAVY. IT CRUSHES DOWN ON ITSELF LIKE THIS SQUEEZING ITSELF TOGETHER, TILL EVENTUALLY AFTER THE WATER IS DRAINED AWAY AFTER A FEW THOUSAND YEARS YOU END UP WITH A ROCK LIKE THIS ONE. SEE THE LAYERS? SEDIMENTARY ROCK HAS LAYERS IN IT.
5:09
THAT'S THE WAY SAND WASHES DOWNSTREAM IN A RIVER. THE LAST TYPE OF ROCK IS SORT OF A COMBINATION OF THE OTHER TWO. WE CALL IT METAMORPHIC ROCK. NOW METAMORPHIC MEANS IT'S CHANGED. IT'S METAMORPHASIZED. SO IF YOU LOOK AT THIS, THIS IS ROCK THAT WAS ONCE SAND BUT IT'S BEEN SMUSHED TOGETHER BY HUGE PRESSURES UNDER VERY HIGH HEAT. PRESSURE AND HEAT SMASHING THE ROCK TILL IT'S JUST CRUSHED FLAT LIKE THIS. UH WHOA!
5:43
SEE, HEAT AND PRESSURE FORMED ANOTHER ROCK.
5:50
WHOA! SO YOU THINK ROCKS ARE BORING? YOU THINK ROCKS ARE STUPID? WELL, IT'S MY JOB AS YOUR GUIDANCE COUNSELOR TO SHOW YOU THAT ROCKS ARE YOUR FRIEND. COME ON, I'LL SHOW YOU. COME ON, RIGHT HERE. WHOOPS SORRY. MADE OF ROCK. (<i> groans</i> ) IN FACT, YOUR WHOLE SCHOOL IS MADE OF ROCKS-- THE FOUNDATION, THE FLOOR, THE WALLS, THE CEILING.
6:19
AND GLASS. IT'S MADE OF SAND, WHICH IS ROCKS. ARE YOU LISTENING TO ME? THIS IS GOOD ROCK.
6:30
IN DIFFERENT PLACES, YOU GET DIFFERENT ROCKS. HERE'S GRANITE WHICH IS BLOCKY AND HAS CRACKS IN IT. OTHER PLACES YOU GET SANDSTONE WHICH IS MORE NUBBY AND IT'S A LOT GRITTIER. IT ERODES AWAY MORE. Boy: GRANITE DOESN'T USUALLY CRUMBLE. IT'S PRETTY SOLID ROCK.
6:57
ROCK CLIMBING'S ABOUT JUST GOING UP ON A ROCK FEELING ROCK BASICALLY GETTING A RUSH FOR THE DAY AND HAVING THE BEST TIME OF YOUR LIFE.
7:09
YEAH!
7:14
Bill: HEY, EDWARD, WHAT ARE YOU DOING? HEY BILL. I'M LOOKING AT THE PATTERNS ON THIS METAMORPHIC ROCK. OH YEAH. LOOK AT IT. IT'S THE PRODUCT OF MILLIONS OF YEARS AND TONS AND TONS OF PRESSURE PER SQUARE METER THOUSANDS OF DEGREES CELSIUS CRUSHING THESE MINERALS TOGETHER... BILL!
7:40
EVERY ROCK YOU SEE USED TO BE DIFFERENT. PLEASE CONSIDER THE FOLLOWING.
7:49
ROCKS ARE ALWAYS CHANGING, ALL OVER THE WORLD AS PART OF SOMETHING WE CALL THE ROCK CYCLE. (<i> shatters</i> ) YOU CAN FIND OUT ABOUT THE ROCK CYCLE NEXT TIME YOU GO WALKING NEAR A VOLCANO. YOU'LL SEE HOT LAVA COMING OUT OF THE GROUND AND COOLING OFF TO FORM NEW ROCKS. NOW, THE REASON WE HAVE VOLCANOES ON THE EARTH IS THAT THE EARTH'S SURFACE, THE EARTH'S CRUST IS MADE OF GIGANTIC PLATES OF ROCK CALLED TECTONIC PLATES. AND THE PLATES ARE ALWAYS MOVING, SHIFTING, EVEN TODAY.
8:24
SO AS THE PLATES ON THE EARTH'S SURFACE MOVE AND SHIFT THEY RUN INTO EACH OTHER. NOW, WHEN PLATES BUMP INTO EACH OTHER ONE PLATE GETS FORCED BELOW THE OTHER ONE. TAKE A LOOK AT THIS. THESE ARE OUR TECTONIC COOKIES OF SCIENCE. IF ONE COOKIE RIDES OVER THE OTHER YOU CAN SEE THAT THE COOKIE UNDERNEATH GETS FORCED DOWN. AND IF THAT WERE ROCK IT MELTS DOWN LIKE LAVA BACK INTO MOLTEN ROCK. AND THE ROCKS ON TOP JUST KEEP GETTING OLDER AND OLDER. NOW, BACK HERE, WHERE THE COOKIE CRUMBLES
8:57
THAT'S WHERE NEW VOLCANOES FORM. THE MOLTEN LAVA COMES UP TO THE SURFACE AND MAKES BRAND NEW ROCKS. THE ROCK CYCLE HAS BEEN GOING ON FOR MILLIONS AND MILLIONS OF YEARS. WELL, THANK YOU FOR JOINING ME ON "CONSIDER THE FOLLOWING." Announcer: ...TO UNDERSTAND THE PROCESSES WE SEE ON THE EARTH'S SURFACE. SEE THESE BIG CRACKS? DO YOU KNOW WHERE THEY CAME FROM? IT WAS FORMED WHEN WATER GOT IN THERE AND FREEZES AND EXPANDS SPLIT THE ROCK APART, MAKES THE CRACK GET BIGGER.
9:32
HAPPENS OVER AND OVER, OVER AND OVER AGAIN-- FREEZING AND REFREEZING AND EVENTUALLY THE WHOLE ROCK IS SPLIT RIGHT OPEN.<i> </i> THIS IS LICHEN-- IT'S A PLANT. IT'S A FUNGUS AND ALGAE THAT WORKS ON THE ROCK. BREAKS IT DOWN-- LOOK AT THIS PLANT. ITS ROOTS ARE GROWING IN THERE AND THEY'LL SPLIT THE ROCK OPEN. AND EVENTUALLY THESE BIG ROCKS GET BROKEN DOWN INTO THIS FINE DUST. AND THIS PROCESS GOES ON ALL DAY, ALL THE TIME. ROCKS GET BROKEN DOWN.
10:13
THE STUDENT CONSERVATION ASSOCIATION PROGRAM IS A PROGRAM FOR YOUNG TEENAGERS TO GET A FEELING OF OUTDOORS AND THEY'RE OUT HERE LIVING OUTDOORS AND WORKING OUTDOORS. THIS IS THE SOIL TO FILL IN THE SOCIAL TRAILS. Boy: A SOCIAL TRAIL IS WHEN YOU TAKE SHORTCUTS AND EVERYBODY ELSE WILL FOLLOW YOU AND THE GRASS WILL START WEARING OUT.
10:38
Girl: ROCKS SHOULD JUST BE HERE TO SUPPORT EVERYTHING DOWN LOW. SO PUT THE GRAVEL ON TOP BECAUSE WHEN THE WATER COMES IN IT'LL PUSH THE DIRT THROUGH THE DAMS AND PIN THE GRAVEL HERE SO IT'LL CLOG EVERYTHING UP SO IT'LL STAY IN PLACE LIKE SOLID GROUND.
10:57
AS YOU CAN SEE HERE, THE SOIL WE'RE PUTTING DOWN IS MADE OUT OF LITTLE BITS OF GRAVEL AND VEGETATIVE MATTER. THIS PROCESS IS ABOUT THE FULL CYCLE-- KEEPING THE PLANTS GOING AND THE SOIL HEALTHY. WE DO THIS TO REPAIR THE NATURAL SETTING.
11:14
TRAILWAYS ARE BASICALLY JUST A PASSAGE FOR YOU TO ENJOY NATURE. THE MORE YOU GO OFF THE TRAILS THE MORE YOU'RE DESTROYING NATURE. ROCKS ROCK. EACH HAS A STORY TO TELL-- IF ROCKS COULD TALK. LIKE THIS ROCK. IT'S CALLED A CONGLOMERATE BECAUSE IT'S MADE OF A BUNCH OF ROCKS GLOBBED TOGETHER. THIS IS SANDSTONE. IT BREAKS APART EASILY BECAUSE IT'S A COLLECTION OF SAND SQUISHED INTO A STONE. WHOA! I'VE GOT A CAMERA ON THE END OF THIS POLE AND YOU CAN SEE HOW THE ACTION OF WAVES
11:53
BREAKS ROCKS DOWN INTO SAND-- SAND THAT MAKES SANDY BEACHES AND SAND THAT WILL ONE DAY BECOME SOIL. THIS PROCESS HAS BEEN GOING ON FOR MILLIONS OF YEARS AND THAT'S WHY THESE TINY WAVES CAN SLOWLY, SLOWLY, SLOWLY MAKE ROCKS INTO SAND AND SAND INTO SOIL.
12:18
Man: STRANGE ROCK FORMATIONS ARE OFTEN DUE TO THE CUTTING ACTION OF SAND HURLED AGAINST ROCK BY THE WIND.
12:29
I'M CHUCK NATSUHARA. I'M A SOIL SCIENTIST WITH THE NATURAL RESOURCES CONSERVATION SERVICE. Girl: I'LL TAKE IT OUT. THESE ARE MY TOOLS. I HAVE AN AUGER THAT I USE TO DRILL DOWN THROUGH A PROFILE.
12:48
Girl: STILL SAND? IT'S REDDISH. Boy: RED, BUT IT WENT TO GRAY. I HAVE A SPADE HERE THAT I CAN USE TO DIG. SEE IF YOU CAN GET ALL THE WAY DOWN HERE TO WHERE IT BREAKS OUT. I HAVE MY KNIFE THAT I USE TO PROBE AND DIG OUT SAMPLES.
13:08
IN THIS PROFILE, WE CAN SEE HOW SOIL IS FORMED. WE CAN SEE THE DIFFERENT LAYERS OR HORIZONS. SOILS FORM ALL THE TIME. THESE ROCKS ARE WEATHERING DOWN TO SANDS AND BEING MIXED WITH OLD PIECES OF WOOD AND ROOTS AND AS THEY ALL COMBINE TOGETHER, THEY PRODUCE SOIL. BY STUDYING SOILS, WE FIND THE BEST WAYS TO USE OUR SOILS-- WHETHER IT'S FOR CROP PRODUCTION OR FOREST PRODUCTION. THROUGH INVESTIGATING DIFFERENT PROPERTIES WE FIND THE BEST WAYS TO UTILIZE OUR SOILS.
13:47
THIS IS A SOIL LAB. NOW, SUPPOSE WE COULD DIG STRAIGHT DOWN INTO THE SOIL PICK IT UP AND LOOK AT IT FROM THE SIDE, LIKE THIS. THIS IS CALLED A PROFILE, AND THESE ARE SOIL PROFILES. YOU CAN SEE<i> </i> THAT SOIL HAS LAYERS. LIKE UP HERE, THERE ARE A LOT OF LIVING THINGS. THEN AS WE DIG DOWN, THE SOIL TURNS LIGHTER AND EVENTUALLY WE FIND THIS LAYER OF CLAY WHICH IS RED. PROBABLY HAS IRON IN IT. THIS IS TOPSOIL. IT HAS LIVING THINGS IN IT AND A LOT OF PLANTS WILL GROW UP HERE.
14:22
IF WE GO DOWN, WE SEE DIFFERENT COLORED SOIL AND PLANTS PROBABLY WOULDN'T GROW AS WELL. SO TOPSOIL IS THIN, AND WE HAVE TO TAKE CARE OF IT. NOW, HERE IS DUST AND THE DUST CAME FROM ROCKS. AS WE DIG DEEPER, WE FIND SMALL ROCKS. WE KEEP GOING DOWN, SLIGHTLY LARGER ROCKS THEN SLIGHTLY LARGER-THAN-THAT ROCKS AND THEN, BIG ROCKS. SEE, SOIL COMES FROM ROCKS. IT ALWAYS HAS. SOIL IS EVERYWHERE. <i> NEW SOIL BARS.</i> ♪ THEY'RE CRUNCHY AND THEY'RE NATURAL ♪ ♪ THEY'RE DIRTY ALL THE WAY ♪

15:22
♪ SHE'LL BE FLOODING DOWN THE MOUNTAIN WHEN SHE COMES. ♪ THAT LOOKS LIKE SAND EROSION. HEY, BILL, WHY ARE YOU PLAYING IN THE SAND? OH, I'M GETTING READY TO RECREATE A GREAT FLOOD IN GEOLOGIC HISTORY. THE FLOOD OVER 16,000 YEARS AGO IN EASTERN WASHINGTON STATE WHERE A HUGE GLACIER BROKE AND SPILLED WATER THAT WASHED AWAY MILLIONS OF TONS OF SEDIMENT EXPOSING THE VOLCANIC ROCK UNDERNEATH? YEAH, BOY, YOU SURE KNOW YOUR ANCIENT FLOODS. WHO DOESN'T?
15:58
Woman: A VAST LAKE FORMED BEHIND GIGANTIC WALLS OF ICE. OCCASIONALLY, ICE DAMS GAVE WAY AND FLOODS SCOURED THE VOLCANIC LANDSCAPE DISPLACING TONS OF ROCKS AND SOIL AS THE WATER FLOWED WESTWARD TO THE SEA.
16:13
HEY WHOA! WHOA!
16:17
HEY, LOOK, IT WORKED. Woman: IN WHAT IS NOW WASHINGTON, A HUGE WATERFALL FORMED. THE ROCKS OF THE DRY FALLS REMAIN TODAY A REMINDER OF THE TORRENT'S POWER. Man: THE WIND CAN CHANGE THE LAND.
16:35
IN THE DESERT, IT BLOWS SAND CHANGING THE SHAPE OF THE LOW SANDY HILLS.
16:49
<i> U-NYEVERSAL PICTURES</i> <i> PROUDLY PRESENTS:</i>
16:57
<i> DON'T TAKE IT FOR GRANTED.</i>
17:00
SEE THESE LITTLE PITS? THESE ARE BUBBLES THAT CAME OUT OF VOL-VOL-V-V-V-VOLCANO... SEE THE PITS IN THIS ROCK? THEY STARTED OUT AS BUBBLES IN A VOLCANO.
17:12
THIS ROCK WAS ONCE A LIQUID.
17:28
DIAMONDS ARE FORMED IN THE NECKS OF VOLCANOES. CARBON WILL CRYSTALLIZE AT TERRIFIC PRESSURE AND HEAT. THAT'S HOW DIAMONDS ARE FORMED. AS A DIAMOND CUTTER, I TAKE THE ROUGH CRYSTAL LIKE THIS AND MAKE IT INTO A GEMSTONE LIKE THIS. DIAMOND IS THE HARDEST SUBSTANCE KNOWN TO MAN. ONLY DIAMOND CUTS DIAMOND. THIS IS DIAMOND THAT HAS BEEN GROUND INTO A POWDER. WE PUT THE DIAMOND POWDER ON THE EDGE OF THE BLADE AND NOW WE CAN CUT THE DIAMOND.
18:13
NOW THAT'S... A ROCK.
18:18
THE ONLY DIFFERENCE BETWEEN THIS PIECE OF COAL AND THIS DIAMOND ARE MILLIONS OF YEARS AND TONS OF PRESSURE PER SQUARE METER. THEY'RE BOTH MADE OF CARBON. THE CARBON IN THIS CHARCOAL ABSORBS ALMOST ALL THE LIGHT THAT HITS IT. IT'S BLACK. BUT THE CARBON IN THIS DIAMOND THAT'S BEEN CRUSHED UNDER HOT MOLTEN ROCK HAS TURNED INTO THIS BEAUTIFUL CLEAR GEM THAT SENDS LIGHT BOUNCING IN ALL THESE DIRECTIONS. THAT'S WHY HUMANS HAVE COVETED DIAMONDS FOR CENTURIES FOR ITS FIERY BEAUTY AND HARDNESS.
18:56
YOU CAN MAKE CRYSTALS USING A LID FROM A LARGE JAR SOME CONSTRUCTION PAPER, SOME SCISSORS SOME HOT WATER AND SOME EPSOM SALT. YOU CAN FIND EPSOM SALT AT ANY DRUGSTORE. FIRST, CUT THE CONSTRUCTION PAPER SO IT FITS INSIDE THE LID.
19:20
THERE.
19:23
NOW PUT SOME EPSOM SALT IN SOME HOT WATER.
19:33
LOOKS LIKE I NEED A LITTLE BIT MORE WATER.
19:38
NOW STIR IT.
19:46
POUR SOME OF THE EPSOM SALT WATER INTO THE LID. MAKE SURE IT JUST BARELY COVERS THE CONSTRUCTION PAPER.
19:55
NOW LET IT SIT FOR ABOUT A DAY.
20:01
COOL. SEE? CRYSTALS FORMED BECAUSE MOLECULES IN THE EPSOM SALT MOVED TOWARD EACH OTHER AS THE WATER EVAPORATED. THEY FORMED PATTERNS JUST LIKE ROCKS. SEE? IT'S CRYSTAL CLEAR.
20:23
