Geology
- Crust
- Oceanic crust
- Ocean-Ocean divergent
- Land separate and lava spew out
- New ocean crust is formed
- Known as mid ocean ridges
- Mid atlantic range
- Ocean-Continental convergent
- Subduction zone, creates a trench
- Also creates Volcanoes
- Ocean-Ocean convergent
- Subduction happens over here
- The upper crust has volcanoes form onto it, creating a volcanic
arc
- Continental Crust
- Continent-Continent convergent
- Can create mountain such as himalayas
- Continent Continent
Transform, Strike slip
- Produces the largest Earthquakes
- San Andreas; Haiti
- jasons notes
- Convergent boundaries
- Usually where all the big and frequent
earthquakes happen
- Subduction generally takes place over here
- Divergent boundaries
- EARTHQUAKES
- Body
- P waves
- Primary waves, fastest to reach
- Are recorded in vibration
- Harder to read the the power of the earthquake
- Parallel to the direction of travel
- S waves
- Shaped like S
- Second waves to reach
- (S wave time - P wave time) * velocity = distance of earthquake
- perpendicular
- Surface
- Rayleigh
- Love
- Conditions for earthquakes
- Cold, brittle rocks
- warm, strong rocks
- Rocks deformation
- Elastic deformation
- Rocks are stretched and respond by elastic rebound and store energy
- Can result in Brittle failure
- Happens when the rocks break and cant return to how they were before
- Liquification
- When pressure squeezes out the water out of lose particles
- Generally bad
