Term
What makes up the Earth's Structure
Definition

Crust:

Mantle: Lower and Upper Layer

Core: Solid inner portion

 


Solid portions of crust and upper layer mantle make up litosphere

Asthensophere is under it

 

Term
Earth Chemical Composition
Definition

 

  1. Earth core consist of hot iron and forms of nickel
  2. Mantle consists of iron, magnesium, and calcium
  3. Crust covers the mantle, lighter rock

 

Term
Folding
Definition

 

  1. When layers of sedimentary rock are pressed together by continental plate movements
  2. Folds upwards are anticlines, downwards are synclines

 Alps and Himalayans

Term
Fault Block Mountains
Definition
Created when tectonic plate movement produces tension that result in displacement. Southwest US
Term
Tectonic Convention
Definition
Like boiling water, heating things rise up when they cool and slowly go back down. A cycle to reach equilibrium
Term
Plate Tectonic Theory
Definition

 

  1. That the lithosphere, solid portion of mantle and earth crust) consists of Major and minor plates
  2. These plates are on top of and move with the viscous upper mantel  because of the heating below

 

Term
Transform Plate Boundary
Definition
two plates slide horizontally with each other, San Andreas Fault
Term
Divergent Boundary
Definition
Plates that spread apart and form new crust
Term
Convergent Boundary
Definition
Process of subduction that causes one plate to go under another
Term
Volcanic Activity at Divergent Boundary
Definition

 

  1. Magma rises to the surface cools and forms a ridge
    1. Mid atlantic ridge

 

Term
Volcanic Activity at Convergant Boundary
Definition

 

  1. Lots of volcanic activity, can create volcanos.
  2. How hawaii was made

 

Term
Types of Volcanoes
Definition

 

  1. Shield
    1. Long term gentle eruption
  2. Cinder Cone
    1. Explosive Erruption
      1. As lava cools creates a cone
  3. Composite
    1. A mixture of both

 

Term
Dynamnic Deformation
Definition

 

  1. Dynamic Deformation
    1. Take the form of P (Primary/Shear) or S(Secondary)
    2. P Waves
      1. Travel fastest
    3. S waves
      1. Shake perpedicularly or transverse to the direction of propagation

 

Term
Types of Faults
Definition

dip-slip: vertical movement along the fault long (wall above fault plane moves down)

strike-slip: horizontal movement across the plane

Oblique-Slip: Both vertical and horizontal

 

Term
Water Cycle
Definition

 

  1. Precipitation
    1. Condensed water vapor falls to earth
  2. Canopy Interception
    1. Lands on plants
  3. Snow Melt
    1. Runoff from melting snow
  4. Infiltration
    1. Water flows from surface into the ground
  5. Subsurface flow
    1. Water that flows underground
  6. Evaporation
    1. When water in a liquid state changes to a gas
  7. Sublimation
    1. When water in a solid state changes to water vapor
  8. Advection
    1. Movemnt of water through the atmosphere
  9. Condensation
    1. When water vapor changes to liquid water
  10. Transpiration
    1. When water vapor is released from plants into the air

 

Term
Major Exctinctions in Earth
Definition
Ordcovician-Silurian, Permian-Triassic, LAte Devonian, Triassic-Jurrasic, Cretaceous-Tertiary
Term
Uniformitarianism
Definition
Gradualism,  that laws have existed throughout geologic time
Term
Catastrophism
Definition
Earth was shaped by sudden catastrophic stuff
Term
Superposition
Definition

 

  1. Law of Superposition
  2. Underground layers closer to the surface were deposited more recently

 

Term
Time Periods of Earth & Current Time
Definition

Eons - > Era -> Periods - > Epoch

We are in Cenozoic

Term
Atmospheric Layers of Earth
Definition

 

  1. Troposphere (Lowest)
  2. Stratosphere
  3. Mesosphere (Coldest)
  4. Thermosphere
  5. Exosphere (Highest)

 

Term
Atmosphere of Earth
Definition

 

  1. Troposphere (Lowest)
    1. weather occurs here
  2. Stratosphere
    1. ozone layer
  3. Mesosphere (Coldest)
  4. Thermosphere
  5. Exosphere (Highest)

 

Term
Hydrosphere
Definition
Earth mostly coegerd by a layer of water/ice called hydrosphere.
Term
Paleozolic Era
Definition

 

  1. Start of Pannotia then ends with Pangaea
  2. Leads to Permian Exctinction, 90% exctinction rate
  3. First land plants, and fish ambian and reptile fossils

 

Term
Cenozoic Era
Definition
Present Day Era, marked after extinction of dinosaurs
Term
Mesozoic Era
Definition

 

  1. Age of Dinosaurs
  2. Large sea levels pangea drifting apart

 

Term
Elkman Transport
Definition
Winds make surface water go and earth rotating move the lower portions which allow dead things to rise to the top for nutrients
