 What is Earth Science?
 Earth Science:
The study of the Earth and of the universe around it.

Examples:
◦ Earthquakes
◦ Volcanoes
 Geology
 Oceanography
 Meteorology
 Astronomy

Study of the origin, history, and structure of
the solid earth and the processes that shape
it.

The study of Earth’s oceans

The study of Earth’s Atmosphere

The study of the universe outside of Earth

Describe TWO reasons that make Earth
Science important to study.

Scientific investigation
Question/purpose
Simple statement of what is being tested.
Scientific investigation
Hypothesis=educated guess
One possible solution to the question that is clearly
testable.
Scientific investigation


A derived unit is a SI unit
of measurement comprised by multiplication or
division between 2 or more base units.
Force = M* A (kg*m/s2)
or
 Density= M/V (g/mL)
 Ex.


Place in a known quantity of water
(100mL,200mL… whatever)
Difference between initial and final
volumes is the volume of unknown

Take the mass and divide it by the unknowns
volume.
 Density=
M/V (g/mL)
