This is Shana and Lilies, National Parks, road trip presentation
- 00:06 - 00:07
and starting from Pella, Iowa.
- 00:08 - 00:10
Our first stop is the Badlands in South Dakota.
- 00:11 - 00:18
Um, the Badlands is a good example of sedimentary rock.
- 00:18 - 00:22
It is formed by the accumulation of the deposition of
- 00:22 - 00:27
mineral or organic particles of the Earth's surface, much like
- 00:27 - 00:27
the Batman.
- 00:28 - 00:34
So it's made of typically made of silk, shale and
- 00:35 - 00:41
sand. Yeah, And then here are some pretty cool pictures
- 00:41 - 00:42
that I found of the Badlands.
- 00:48 - 00:52
So going from the Badlands will travel to Devil's Tower,
- 00:53 - 00:57
and this is a good example of indigenous rock.
- 00:59 - 01:04
This rock is formed through the cooling and solidification of
- 01:04 - 01:06
magma or lava, much like Devils Tower.
- 01:07 - 01:13
Yeah, so the devils tower is made up of very
- 01:13 - 01:14
rare rock.
- 01:15 - 01:17
Um, it's a funnel light, which is like a fine
- 01:17 - 01:21
grain volcanic rock, and it's composed of alkali feldspar airs
- 01:21 - 01:24
and Neff line and then pour free.
- 01:25 - 01:29
It's a rock that contains crystals, usually a feldspar in
- 01:30 - 01:32
a fine grain, typically reddish ground mass.
- 01:37 - 01:39
And then here are some pictures of Devils Tower.
- 01:40 - 01:43
Yeah, Okay.
- 01:45 - 01:50
Okay. So our next stop is Mount Rainier National Park,
- 01:50 - 01:53
and this park has a lot of examples of convergent
- 01:54 - 01:54
plate boundaries.
- 01:55 - 02:01
So convergent plate boundaries, um, they are usually like an
- 02:01 - 02:04
old material, um, is pushed together and taken into the
- 02:04 - 02:05
earth's interior somewhere else.
- 02:06 - 02:09
Um, it's a place where two plates are coming together.
- 02:09 - 02:13
One place sinks beneath another to form a subduction zone,
- 02:14 - 02:16
and the plate is subjected or taken beneath.
- 02:17 - 02:20
In this way sinks down to rejoin the mantle material
- 02:21 - 02:22
from which it came.
- 02:26 - 02:30
Mount Rainier is 14,000 ft volcano in the Cascade Range,
- 02:31 - 02:34
Um, and it's developed above the place where the Subject
- 02:34 - 02:39
Inc Juan de Fuca plate, reaches sufficient depth to release
- 02:40 - 02:43
hot fluids into the overriding North American plate.
- 02:47 - 02:51
Mhm. So our next stop is Death Valley, and this
- 02:51 - 02:53
will be our ecosystem part.
- 02:53 - 02:56
So Death Valley is the hottest and driest and lowest
- 02:57 - 02:57
national park.
- 03:00 - 03:01
So what is an ecosystem?
- 03:02 - 03:05
It's a place of living for a biological community of
- 03:05 - 03:08
interacting organisms, and the picture I provided is like a
- 03:08 - 03:14
picture of an ecosystem and where things live, yeah, and
- 03:14 - 03:16
then some animals that live there.
- 03:16 - 03:19
There's a coyote, and they like to hunt mainly rabbits
- 03:19 - 03:22
and rodents and then a desert tortoise and their diet
- 03:23 - 03:27
mostly consists of herbs, grasses, shrubs and flowers and then
- 03:28 - 03:28
a rosy boa.
- 03:29 - 03:35
And their diet consists, or of rodents, chickens, lizards, amphibians
- 03:35 - 03:36
and other snakes.
- 03:37 - 03:46
Okay, so the next stop is Yosemite National Park, and
- 03:47 - 03:50
a big part of Yosemite National Park is Yosemite Valley.
- 03:51 - 03:55
So it's, um, located in Yosemite National Park, like I
- 03:55 - 03:58
said, and we're going to talk about the hydraulic cycle
- 03:59 - 04:00
for this national park.
- 04:01 - 04:06
And, um, Yosemite Valley is actual is actually a glacial
- 04:07 - 04:12
valley, and the hydro hydraulic cycle is the combination of
- 04:12 - 04:16
processes by which water moves from respiratory to respiratory above,
- 04:16 - 04:18
below in on Earth service.
- 04:18 - 04:23
So the first part of the water cycle is evaporation.
- 04:24 - 04:26
Um, evaporation is a process of a liquid turning into
- 04:27 - 04:27
a gas.
- 04:27 - 04:30
Water can come from the ocean lakes or rivers and
- 04:31 - 04:33
evaporates and then becomes water vapor into the air.
- 04:34 - 04:36
Um, this is made possible by the sun.
- 04:36 - 04:39
Evaporation is also influenced by wind and the temperature.
- 04:40 - 04:43
Yeah, so the next part of the water cycle is
- 04:44 - 04:47
condensation, and condensation is when a gas turns into a
- 04:47 - 04:51
liquid and water vapor becomes a liquid, Um, condensation can
- 04:51 - 04:54
happen high in the atmosphere or even down at ground
- 04:55 - 04:58
level. Um, clouds can form in the sky, and then
- 04:58 - 05:01
fogger miss kind of forms down low, and then when
- 05:01 - 05:04
water vapor cools down, it reaches a dew point.
- 05:05 - 05:06
As you can see the dewdrops on the window in
- 05:06 - 05:11
the picture, the next part is precipitation, and that has
- 05:12 - 05:14
any liquid or solid that falls to the earth that
- 05:14 - 05:15
happens from condensation.
- 05:16 - 05:22
Precipitation can be rain, snow and hail and a glacial
- 05:22 - 05:28
valley. Actually, Yosemite Valley is glacial valley, and water is
- 05:28 - 05:29
always changing the three states.
- 05:30 - 05:32
It changes into our solid liquid and vapor.
- 05:33 - 05:35
Most of Earth's fresh water is ice, and it's locked
- 05:36 - 05:38
in massive glaciers, ice sheets and ice caps.
- 05:39 - 05:42
When ice melts, it turns into a liquid the melting
- 05:42 - 05:45
of glaciers in erosion caused by water or two of
- 05:45 - 05:45
the ways.
- 05:46 - 05:50
The water cycle helps create Earth's physical features, and when
- 05:50 - 05:54
glaciers expand, they leave valleys, create mountain peaks and lay
- 05:54 - 05:55
behind rebel.
- 05:55 - 05:58
And then Yosemite Valley is a glacial valley.
- 05:59 - 06:03
Um, that kind of shows in the picture there you
- 06:03 - 06:04
should look like.
- 06:05 - 06:09
So next we'll be traveling to Courtesan Mountain.
- 06:10 - 06:13
Um, it is a good example of the metamorphic rock.
- 06:14 - 06:17
It is the metamorphic is a transition of existing rock
- 06:17 - 06:18
to new types of rock.
- 06:19 - 06:23
The original rock is, uh, subjected to temperatures greater than
- 06:23 - 06:25
1 50 to 200 degrees Celsius.
- 06:25 - 06:28
And often Evelyn are evaluated pressure.
- 06:28 - 06:30
Uh, yeah.
- 06:30 - 06:32
So courtesan is a good example of that.
- 06:33 - 06:36
What's it made up of?
- 06:36 - 06:41
Mostly high heat, high pressure and hot mineral rich fluids.
- 06:42 - 06:44
Or, more commonly, some combination of these factors.
- 06:45 - 06:48
And that picture kind of like explains how it happens.
- 06:51 - 06:54
And then here are some pretty pictures of Catoctin Mountains,
- 06:56 - 07:01
Okay? And our last stop of the road trip is
- 07:01 - 07:04
the Hawaii Volcanoes National Park, which is in Hawaii.
- 07:05 - 07:08
Um, the volcanoes in this park are actually an example
- 07:09 - 07:10
of divergent plate boundaries.
- 07:10 - 07:15
Um, we've previously talked about convergent plate boundaries, and then
- 07:15 - 07:17
these are pictures of the actual park, the volcanoes in
- 07:17 - 07:17
the park.
- 07:19 - 07:22
So a divergent plate boundary plates lie above the zone
- 07:23 - 07:24
where magma comes out of the surface.
- 07:24 - 07:25
They form a chain of mountains.
- 07:26 - 07:28
Magma pushes the plates further away from each other.
- 07:29 - 07:32
Molten material cools to rock and becomes new plate material.
- 07:33 - 07:36
Earthquakes of low energy can occur, and then the C
- 07:37 - 07:40
four spreads and then lava erupts from the newly created
- 07:40 - 07:45
fish years, and plates are pushed apart, and any continents
- 07:45 - 07:47
that might be located on other portions of those plates
- 07:48 - 07:49
are pushed apart as well.
- 07:51 - 07:55
Um, the park is actually 45 minutes from, uh, Hilo
- 07:56 - 08:00
and extending from the sea level to 13,677 ft.
- 08:01 - 08:03
The park encompasses the summit of two of the world's
- 08:04 - 08:10
most active volcanoes, and so the actual volcanoes are examples
- 08:11 - 08:15
of the divergent plate boundaries, and then, lastly, we have
- 08:15 - 08:16
our sources.
