Convergent Boundaries
+ One plate slides underneath another (subduction) <Types> \+thrust/reverse faults <Outcomes> \+Earthquakes, Tsunamis, Volcanoes, Trenches, Mountains </Outcomes></Types>
Divergent Boundaries
+ Two tectonic plates move apart <Types> \+Normal faults <Outcomes> \+Earthquakes, Mid-Oceans ridges (magma being released), Volcanoes </Outcomes></Types>
Transforming Boundaries
+ Two plates slide against each other <Types> \+Strike- slip fault <Outcomes> \+Earthquakes, and strike-slip fault </Outcomes></Types>
Erosion
+ Physical movement of a rock
Island Arcs
+ The presence of Volcanoes as as a chain that form in the convergent boundaries where one oceanic plate subducts another
Subduction (extra)
+ To move under another structure or plate
Hot spots
+ Located at the bottom of a volcanoes and below the magma + where magma is released from + more hot than the actual magma
Parent Material
+ rock material from which soil derived
Soil Horizons
+ zone or layers of the ground that are built over time
Soil erosion
+ topsoil being wearing away due to wind and water
Porosity
+ Space between particles
Permeability
+ how every water can flow through.
Soil Texture Triangle
+ A map to determine the soil texture type
Watershed
+ An area of high natural erosion activity + Can regulate climate in the area
Insolation
+ the amount of exposure to the sun’s rays
Gyre
+ A large side pattern of surface water circulation that moves clockwise in the southern hemisphere + Driven by atmospheric cells + Redistributes heat
Upwelling
+ the process where cold, nutrient rich water rises from the deep ocean to the surface + replaces the old, hot nutrients with new ones + helps grow surface vegetation such as plankton
Thermohaline
+ a large map of the oceanic circulation based on the density of the water and salinity
Convection
+ the transfer of heat due to the movements of air or water because of the differences with temperature in density
Weathering
+ actively breaking down in a rock ( done by water )
Deposition
+ accommodation of eroded materials (or) + the dropping of sediment into a new place
Albedo
+ the percentage of incoming sunlight reflected from a surface
Weather
+ the cycle of changes in seasons + like daily temperatures
Climate
+ average of these conditions over long periods of time
