Question
I really ned help defining all these terms. I partiularly need to tie the concept back to the term in the bold above it. Please describe EACH as much as possible.
Plate Tectonics
How different mountain ranges form? How do islands compare? What goes on in faults versus?
Pangea: evidence
Magnetic evidence
Sea floor spreading: what drives it
Lithospheric plates (do not memorize the plate names);
Relationship to earthquakes,
How seismology reveals the earth’s interior (S & P waves),
Oceanic vs continental crust: isostatic adjustment.
Plate boundaries:
Divergent: constructive plate boundaries: spreading centers: stages of ocean formation
Convergent: destructive plate boundaries: subduction, trenches
Oceanic-continentalàcontinental mountain arc
Oceanic-oceanicàisland mountain arc
Continental-continentalàmountain range
Transform plate boundaries: faults and fracture zones
Wilson cycle: (puts it all together)
Hot spots: formation of Hawaiian islands and contributes to Iceland
Before Pangea: Rodinia & SWEAT
Bathymetry
Mapping the ocean floor: echo soundings & its many variations; seismic reflection profiling; satellite altimetry
Provinces: active vs. passive
Continental shelves: variations; continental slopes with submarine canyons from turbidity currents- turbidites & deep-sea fans; continetal rise; abyssal plain.
Spreading centers: ridges and rises: form volcanic islands, guyots, seamounts & abyssal hills
Hydrothermal vents
Transform faults and fracture zones
Trenches: “ring of fire” + other areas of subduction
Sediments
Classifying sediments
Size & texture: how they transport, settle and erode (Please do not memorize the size of each)
Sorting
Maturity
Origin: Litho-, bio- hydro- or cosmogenous Know formation & examples
How do sediments get to their locations?
Water, wind, ice rafting, stromatolites (fossils), turbidity currents, slumping
Oozes: Si & Ca: solubility; carbonate compensation depth
Fecal pellets
Explanation / Answer
Answer for following question
How different mountain ranges from?
Answer: Mountain rages forms by the tectonic boundary movements like convergent boundaries. In these convergent boundaries, plates can be colliding each other then form the mountains with high elevation.
