Unit 1: A Fragile System
At least 3 earthquake recording stations are required to find the location of the earthquake epicenter. A single recording station can only calculate distance, but not direction; to cover all possibilities, a complete circle is drawn around that station. If only two earthquake recording stations are used, the circles will overlap at two points. Data from a third recording station will eliminate one of these points.
Explain what density is & how it relates to stratification.
Density = mass/volume; how much mass fits into a space. Unit: kg/m3 3
Stratification = less-dense materials float on top of denser materials

Viscosity: measure of how much fluids resist flowing or changing their shape.
Greater viscosity, more resistance. Depends on temperature + chemical structure.
Compressibility: ability to be squeezed/expanded. Results in a change in density because of volume change.
Phases of matter
Solids: Not fluid, not very compressible.
Liquids: Very fluid, not very compressible.
Gases: Very fluid, very compressible.
Be able to diagnose the type of strain by the way a material deforms.
Strain: Change in shape or size of a solid object (deformation)
Elastic: Ability to change shape when forced but spring back to original shape when force lifted
Plastic: Ability to permanently change shape or deform when forced
Ductile = very plastic, Brittle = not very plastic, fractures instead of bending.
Explain how gravity affects motion and energy, list the 5 types of energy, and describe what causes them to vary.
Unit: Newton = 1 (kg * m/s^2) -> F = ma
A 15 km/h breeze = 1 N
Force that attracts matter
G = 9.8 m/s2 = gravitational acceleration
Types of Energy
Work = force x distance in = Joules
Mass * gravity * height (distance against pull of gravity)
