2. This is the Box Springs
Mountains located in Riverside,
CA near my home. Mountains
are caused by sliding plates.
This mountain range is
characterized by granite rock
outcrops and large boulders
and has underlying granitic
bedrock. (GEOLOGY AND
SOILS) Also there was once an
inland sea here and many more
ecosystems. These mountains
were formed in the Pliocene
epoch (GEOLOGY AND SOILS)
3. This is a Limestone rock,
which is a sedimentary
rock. It is made made
from calcite (12
Common Sedimentary
Rocks) . This would
imply that some type of
lake or water area used
to be in this area
because these rocks
come from sea shells
and evaporated seas.
These rocks come with
time and accumulation
of sediments.
4. This is an example of the
many boulders on Box
Springs Mountain. This
boulder is sedimentary
rock and more specifically
sandstone. It was fine-
grained as well. Boulders
are a sign of erosion
(Boulder).. Boulders can be
evidence of glaciation as
well given that many
boulders are glacial
erratic's which were picked
up by ice sheets and
deposited later in time.
This could be why these
boulders do not fit with a
lot of the other rocks here.
5. This is an Igneous rock or more
specifically granite. This rock is
different from the other
sedimentary rocks I have observed.
This rock in particular is not fine
grained like the others and is
igneous. This rock most likely
contains quartz like most of the
other rocks here however igneous
rocks come from lava so this rock
would have came from deep down
under us (Granite)! This rock
originally came from magma which
then cooled down and broke off.
Overtime and breaking down, it
finally gained the appearance it has
today.
6. These are Eucalyptus trees. What is
so important about these trees is
that it marks a water source
originally existing here! (Box
Springs Mountain). These trees
give rise to many life forms and
show that even though these
mountains may look dead now
there was lots of inhabitants here
in earlier times and especially in
the Pleistocene. Eucalyptus can
take the form of trees and shrubs
as shown. These trees were
originally called gum trees. These
Eucalyptus trees are not as
common today but in the
Pleistocene there were many of
them.
