00:00:00.000 --> 00:00:04.683
- You have an elevator ride
with one of these students.

2
00:00:06.100 --> 00:00:08.720
You're gonna tell them,
what's important about caves,

3
00:00:08.720 --> 00:00:10.620
in sort of a quick, condensed version.

4
00:00:11.720 --> 00:00:12.553
Can you help us with that?

5
00:00:12.553 --> 00:00:13.386
- I got this one.

6
00:00:13.386 --> 00:00:14.219
- Okay, sweet.

7
00:00:14.219 --> 00:00:15.470
- So we talked about water all along,

8
00:00:15.470 --> 00:00:17.220
we've kind of mentioned water.

9
00:00:17.220 --> 00:00:21.830
In 40 percent of the US and
25 percent around the world,

10
00:00:21.830 --> 00:00:23.640
water comes from cool places like this,

11
00:00:23.640 --> 00:00:25.540
where there are caves called karst areas,

12
00:00:25.540 --> 00:00:26.780
which was one of our glossary words

13
00:00:26.780 --> 00:00:28.400
from the first CavesLIVE.

14
00:00:28.400 --> 00:00:30.930
And so, caves are super
important to protect

15
00:00:30.930 --> 00:00:33.080
because our drinking
water comes out of caves,

16
00:00:33.080 --> 00:00:34.864
as well as water for recreation,

17
00:00:34.864 --> 00:00:37.884
and water for unique plants
and animals that depend on

18
00:00:37.884 --> 00:00:40.254
water beneath the surface
of the earth or at springs

19
00:00:40.254 --> 00:00:43.100
where that water from the subsurface

20
00:00:43.100 --> 00:00:44.510
comes out at the surface.

21
00:00:44.510 --> 00:00:47.500
So, water's a big, big part of why caves,

22
00:00:47.500 --> 00:00:49.760
cave systems, and karst areas as a whole

23
00:00:49.760 --> 00:00:51.177
are very important.

24
00:00:53.040 --> 00:00:54.780
- [Host] I'd like to ask
that question of all of you.

25
00:00:54.780 --> 00:00:59.670
- Yeah, so they're important
because they hold sediments,

26
00:00:59.670 --> 00:01:02.520
as you can see, there's
sediments in the caves.

27
00:01:02.520 --> 00:01:04.560
Speleothems, are also a type of sediment,

28
00:01:04.560 --> 00:01:07.230
so those sediments are records for us

29
00:01:07.230 --> 00:01:09.410
to study the climate in the past.

30
00:01:09.410 --> 00:01:11.170
So we learn about the temperature,

31
00:01:11.170 --> 00:01:12.850
we learn about the rainfall,

32
00:01:12.850 --> 00:01:14.310
and we can make predictions

33
00:01:14.310 --> 00:01:16.420
of what's going to happen in the future.

34
00:01:16.420 --> 00:01:18.920
They are comparable to tree ring records.

35
00:01:18.920 --> 00:01:20.950
I'm sure you guys have
heard about tree rings,

36
00:01:20.950 --> 00:01:23.671
or deep sea sediments
or even glacier records.

37
00:01:23.671 --> 00:01:26.870
So we can find the similar type of signs,

38
00:01:26.870 --> 00:01:28.010
and then correlate it

39
00:01:28.010 --> 00:01:30.123
with what's happening outside the cave.

40
00:01:31.290 --> 00:01:33.460
- And Lima, that is very important,

41
00:01:33.460 --> 00:01:35.030
because with the sediments,

42
00:01:35.030 --> 00:01:38.700
that's what protects
the animals that died,

43
00:01:38.700 --> 00:01:40.300
and then preserved them

44
00:01:40.300 --> 00:01:43.820
so that we can find them
later and study them.

45
00:01:43.820 --> 00:01:46.880
Usually, the animals, maybe
that are found in caves,

46
00:01:46.880 --> 00:01:49.580
may not have been preserved anywhere else.

47
00:01:49.580 --> 00:01:52.980
And so, we've got this cave
that helps preserve and

48
00:01:52.980 --> 00:01:56.570
promote science and gives
us a lot more information

49
00:01:56.570 --> 00:01:58.820
about what the climate was like,

50
00:01:58.820 --> 00:02:01.753
and what was influenced
by the caves, yeah.

51
00:02:03.326 --> 00:02:04.159
- Thank you.

52
00:02:04.159 --> 00:02:04.992
- Yeah.

53
00:02:04.992 --> 00:02:05.990
- Alright, I appreciate
that elevated speech

54
00:02:05.990 --> 00:02:07.310
because 'cause we wanted
you all to remember

55
00:02:07.310 --> 00:02:09.453
all the things that are
important about caves.
