JOAN CARTAN-HANSEN, HOST: 
GEOLOGISTS STUDY THE FORCES

2
00:00:03,433 --> 00:00:04,734
THAT HELP SHAPE OUR WORLD.

00:00:04,734 --> 00:00:07,900
FIND OUT MORE ABOUT THE ROLE 
GEOLOGY PLAYS IN YOUR LIFE...

00:00:08,333 --> 00:00:12,100
(MUSIC)

5
00:00:13,800 --> 00:00:15,333
>> WHAT ARE YOU READING?

6
00:00:15,333 --> 00:00:18,100
>> A BOOK ON GEOLOGY.

7
00:00:18,100 --> 00:00:18,900
>> GEOLOGY?

8
00:00:18,900 --> 00:00:21,633
WHY WOULD YOU WANT TO KNOW ABOUT 
GEOLOGY?

9
00:00:21,633 --> 00:00:24,500
>> BECAUSE IT PLAYS A IMPORTANT 
ROLE IN YOUR LIFE.

10
00:00:24,500 --> 00:00:28,633
A GEOLOGIST STUDIES HOW THE 
EARTH'S CRUST IS FORMED AND WHAT

11
00:00:28,633 --> 00:00:34,166
MATERIALS IT'S MADE UP OF 
WITHOUT GEOLOGISTS YOU WOULDN'T

12
00:00:34,166 --> 00:00:36,433
HAVE A LOT OF THINGS YOU USE 
EVERY DAY.

13
00:00:36,433 --> 00:00:40,967
LIKE WHAT?

14
00:00:40,967 --> 00:00:44,533
>> LIKE THE FLUORITE IN YOUR 
TOOTHPASTE OR THE FELDSPAR IN

15
00:00:44,533 --> 00:00:46,433
YOUR DISHES.

16
00:00:46,433 --> 00:00:50,433
LOOK AROUND YOUR HOUSE, ALL OF 
THESE ARE MADE UP OF MINERALS.

17
00:00:50,433 --> 00:00:54,734
MINERALS ARE MADE UP OF THE 
BASIC ELEMENTS OF EARTH.

18
00:00:54,734 --> 00:00:58,367
GEOLOGISTS STUDY THE SURFACE 
FORMATIONS AND TYPES OF ROCK TO

19
00:00:58,367 --> 00:01:00,433
FIND MINERALS.

20
00:01:00,433 --> 00:01:05,533
ONCE THEY IDENTIFY A DEPOSIT, 
THEY'RE EXTRACTED AND PROCESSED

21
00:01:05,533 --> 00:01:08,000
AND MADE INTO THINGS IN YOUR 
LIFE.

22
00:01:08,000 --> 00:01:10,700
IDAHO IS CALLED THE GEM STATE 
FOR A GOOD REASON.

23
00:01:10,700 --> 00:01:14,900
YOU CAN FIND MORE THAN 240 
DIFFERENT MINERALS IN IDAHO.

24
00:01:14,900 --> 00:01:19,900
EVERYTHING FROM ACANTHITE TO 
ZOISITE.

25
00:01:19,900 --> 00:01:23,433
EVEN THE STATE GEM IS A MINERAL.

26
00:01:23,433 --> 00:01:24,700
THE STAR GARNET.

27
00:01:24,700 --> 00:01:27,333
>> WHAT ELSE DO GEOLOGISTS DO?

28
00:01:27,333 --> 00:01:30,533
>> THEY HELP TO DEVELOP MAPS AND 
STUDY ROCKS TO LEARN MORE ABOUT

29
00:01:30,533 --> 00:01:33,867
PLANTS AND ANIMALS THAT WERE 
ALIVE MILLIONS OF YEARS AGO.

30
00:01:33,867 --> 00:01:37,100
AND RESEARCH THE IMPACT OF 
FORCES LIKE EROSION AND

31
00:01:37,100 --> 00:01:40,867
INVESTIGATE HOW VOLCANOS FORM 
AND ANALYZE FAULTS IN THE GROUND

32
00:01:40,867 --> 00:01:44,633
TO LEARN HOW TO PREDICT 
EARTHQUAKES AND THEY DON'T JUST

33
00:01:44,633 --> 00:01:45,800
STUDY THE EARTH.

34
00:01:45,800 --> 00:01:49,600
THEY STUDY ROCKS ON OTHER PLANET 
TO LEARN MORE ABOUT OUR

35
00:01:49,600 --> 00:01:50,166
UNIVERSE.

36
00:01:50,166 --> 00:01:52,100
>> HOW DOES THAT AFFECT ME?

37
00:01:52,100 --> 00:01:55,333
>> WELL, COME SEE.

38
00:01:55,333 --> 00:01:56,900
>> IT'S COLD!

39
00:01:56,900 --> 00:01:59,900
>> LOOK AROUND, WHAT DO YOU 
THINK WOULD HAPPEN IF A DAM

40
00:01:59,900 --> 00:02:04,600
FAILED?

41
00:02:04,600 --> 00:02:07,266
>> THAT WOULD BE TERRIBLE!

42
00:02:07,266 --> 00:02:11,166
>> GEOLOGISTS FIGURE OUT WHERE 
TO PLACE DAM AS BUILDINGS AND

43
00:02:11,166 --> 00:02:12,066
OTHER THINGS.

44
00:02:12,066 --> 00:02:13,367
PLACES WHERE THE GROUND IS 
STABLE.

45
00:02:13,367 --> 00:02:15,367
THEY WORK TO KEEP US SAFE.

46
00:02:15,367 --> 00:02:16,700
THAT'S COOL.

47
00:02:16,700 --> 00:02:19,600
SPEAKING OF COOL -- 
>> OH, YEAH.

48
00:02:19,600 --> 00:02:20,266
>> WHOA!

49
00:02:20,266 --> 00:02:23,266
BECOMING A GEOLOGIST CAN REALLY 
BE INTERESTING.

50
00:02:23,266 --> 00:02:23,967
>> YEAH.

51
00:02:23,967 --> 00:02:28,433
>> HEY, YOU TWO COULD BE AMATEUR 
GEOLOGISTS RIGHT NOW.

52
00:02:28,433 --> 00:02:31,600
GO OUTSIDE AND EXPLORE, LEARN 
ABOUT THE LAND AROUND YOU.

53
00:02:31,600 --> 00:02:38,500
IT'S JUST THE BEGINNING OF THE 
GREAT ADVENTURE IN GEOLOGY.

54
00:02:38,500 --> 00:02:40,700
