angiosperms used photo

plants do not.
Snow plants can dwell in

Existence

the Jurassic period.
3. AMERICAN
BLACK BEAR
Adaptations
• Larger size
• More brute strength
• Advanced hunting
skills, to be able to
take down various
animals.
• Evolution
• Much bigger than its
ancestors.
• Bears in the past
could run faster.
• Killers of larger prey.

Pleistocene" (Extinct
Short-faced Bear, 2017).

4. CANADIAN
GOOSE
Evolution
"Type:
Bird
Diet:
herbivore
Anseriformes
Family:
Anatidae"
(Canadian
Goose, n.d.).
Adaptations:
Eats grasses, grains, or
berries. Migrates when food
is unavailable. Like cold
regions and native areas.
Geese "threat displays may
involve head pumping, bill
opened with tongue raised,
hissing, honking, and
vibrating neck feathers"
(Canada Goose, 2015).
Along with a special beak
that picks up water. Oldest
goose was older than 70
years old.
Existence
In the fossil record of
North America during the
Miocene era. Fossils
also found in
the Hawaiian Islands.
Oldest dating ancestor of
Anseriformes was the
Anatalavis rex of
the "Late Cretaceous or
early Paleocene" (
Ducks, Geese, and
Swans (Anatidae),
2004).
• Past birds laid more
eggs.
• Polygynous

5. Diorite forms from the
cooling of magma. An
intrusion also occurs
within the series of
events. The magma
gets trapped under the
Earth's crust and
begins to form. Meyers
Diorite Unlike many rocks
diorite has a small
amount of quarts and
is very hard to find.
Diorite is an “igneous rock
composed principally of the
silicate minerals plagioclase
feldspar (typically andesine),
biotite, hornblende, and/or
pyroxene. The chemical
composition of diorite is
intermediate, between that of
mafic gabbro and felsic
granite. Diorite is usually grey
to dark-grey in color, but it can
also be black or bluish-grey,
and frequently has a greenish
cast” (Diorite - Wikipedia,
n.d).
6. Granodiorite
Granodiorite is very
speckly and is very
dense. Certain pressure is
required to break the
rock.
Is an “medium-to coarse-grained rock similar to granite, it has more plagioclase
feldspar than orthoclase feldspar. Granodiorite can be pink or white with a grain
size and texture similar to granite, but the plagioclase generally makes it
appear darker, and the hornblende and biotite that are often present give it a
speckled appearance” (Granodiorite, 2008).
Granodiorite “formed by an intrusion of silica-rich
magma, which cools in batholiths or stocks below
the Earth's surface. It is usually only exposed at
the surface after uplift and erosion have occurred”
(Granodiorite - Wikipedia, n.d).
Many of the rocks are used for construction jobs such as building
roads, the durable strength of the rock makes it useful for bearing
heavy weight. Within the rock is everyday elements like soidum
that is in food. Iniside is even some magnetite, which of course is
obtained by using a magnet. Fallen Leaf Trail
7. Granite
Granite consists of “felsic
intrusive igneous rock that
is granular and phaneritic
in texture. Granites can be
predominantly white, pink,
or gray in color, depending
on their mineralogy. . .
granite is an igneous rock
with between 20% and
60% quartz by volume, and
at least 35% of the total
feldspar” (Granite -
Wikipedia, n.d0Granite -
Wikipedia, (n.d.).
Granite is a very tightly
packed rock. The grain is
very well fitted. The rock
is also dense as other
rocks.
Granite forms by magma
intrusions dropping
temperatures and
turning into
plutons. After a certain
time the rock starts to
harden
and become more stable.

8. Law of
Superposition
The principle of superposition involves
layers of rock, in which the lowest layer is
oldest and the highest layer is the
youngest.
There is a slight disconformity on
highway 50 rock layers represented show
horizontal layers in which the youngest
larger layer is above and the oldest rock is
ground level.

9. “A SURFACE BETWEEN SUCCESSIVE STRATA REPRESENTING A
MISSING INTERVAL IN THE GEOLOGIC RECORD OF TIME, AND
PRODUCED EITHER BY AN INTERRUPTION IN DEPOSITION OR BY THE
EROSION OF DEPOSITIONAL CONTINUOUS STRATA FOLLOWED BY
RENEWED DEPOSITION” (UNCONFORMITY, 2005).
The rock formation to the right
is angular and has different
layers of rock ages. Also, the
rock appears to have been
weathered. At the bottom of
the rock formation is what
looks like a fault.
