What is the study of earth exactly?




Earth science is going to cover a lot of things.
The earth has lots of different systems that we
will go through.
The four main branches of earth science are
Astronomy, Meteorology, Geology, and
Oceanography
Pretty much all Earth science can be put into
one of these four branches



To go along with the four main systems of the
Earth Science, There are four systems that go
as follows: the lithosphere, the hydrosphere,
the atmosphere, and the biosphere.
Lithosphere: crust and mantle
Hydrosphere: water system
Atmosphere: gases surrounding the earth
Biosphere: All living organisms

Stars, Aliens, Planets, Out of this world
The study of astronomy might not deal with
aliens (we have not come up with evidential
proof yet) but it does include everything that is
not on our current planet.
Gotta use special instruments to study: space
ships, telescopes, etc.


The study of knowing with its going to rain
(among other weather elements)
Meteorologists study the forces and processes
that cause the atmosphere to change to produce
weather.
They also try to “predict” what will happen
next.



Rocks! More and more rocks.
Geology is the study of the materials that
make up Earth and the processes that form and
change these materials.
Any rock collectors out there?

You guessed it. This is the study of the ocean.
Why not though, it takes up 3/4ths of Earth’s
surface
This is the study of the ocean in all that that
encompasses (animal/plant life, chemical
issues, currents, etc.)
Why are these important?

SI stands for Systeme International d’Unites
Internationally, this is the system that we will
use measure anything in science.
There are several things that get measured
Length, Mass, Volume/Area, Density, Time,
Temperature


Measured in Meters
(m)
How long something
is or the distance
between two objects



Measured in grams
(g)
The amount of matter
in an object
Not the same as
weight but similar




Area is measured in
m2
It is the amount of
space on the surface
something takes up.
Volume is measured
in the milliliter (mL)
or cm3
About of space
something takes in 3D





Amount of matter that
occupies a given space
Doesn’t have a special
unit to itself.
Labeled g/mL or
g/cm3
Aka mass/volume
No tool to measure


Internationally time is
measured by seconds
(s)
Usually is going to be
measured by a watch
or a timer



In science we do no
use the Fahrenheit
scale. We use Celcius
(C°)
We could also
measure in Kelvin but
that’s less important
at the moment
Use a thermometer






There are bigger and
smaller units of each
base units
Length-meter(m)
Mass- gram (g)
Volume- Liter (L)
Time- second (s)
Temperature- Celcius
(C°)

HINT!
If you are getting
bigger divide.
If you are getting
smaller multiply
