Plate Tectonics
This process drives tectonic plate movement
convection in the mantle
We in Florida live in what hemisphere?
Northern Hemisphere
This process contributed to the accumulation of water for the early oceans
convection (heating and cooling)
This feature defines a divergent boundary
mid ocean ridge
These features are characteristic of a convergent boundary
mountains and trenches
The difference between oceanic and continental crust is
composition and density
This is the reason why the northern and southern hemispheres have opposite seasons
The earth's tilt
These are 3 pieces of evidence for continental drift
similar geography, fossils, continents fitting together
The switching of the earth's poles is recorded how?
Direction of crystallization of new ocean floor at the mid ocean ridge
When we have oceanic-continental collision, this happens
subduction of the oceanic plate due to higher density
Crust is created at ________________ and destroyed at___________________
mid ocean ridge; subduction zones
This point on earth indicates 0 degrees longitude
Prime meridian
This early version of the continents is called
Pangea
If you were to walk to the Atlantic mid ocean ridge, what features would you come across before reaching the abyssal plain?
Continental shelf, shelf break, slope, rise
When we have continental-continental collision, this feature forms
mountains
The west coast of south america is considered a(n) ______________________ boundary
The five oceans are
Atlantic, Pacific, Indian, Southern, Arctic
As humans, we live on the layer of the earth called the_____________________
lithosphere
The continental rise forms by
accumulation of sediment from the continental slope
short
This feature of the ocean helps us track the movement of tectonic plates (hint: Hawaiian islands)
volcanoes and island hot spots
The seven continents are
North America, South America, Asia, Australia/Oceania, Africa, Europe, Antarctica
The layers of the ocean, in order, are
epipelagic, mesopelagic, bathypelagic, abyssalpelagic, hadopelagic
These are things that you might observe in the abyssal plain
seamounts, guyots, mountains, volcanoes
This area of this ocean is famous for its active margins
ring of fire; pacific
