Fun Facts
Two types of the most common elements found in the crust and the mantle
What are silicon, magnesium, oxygen, calcium, carbon, aluminum, sodium, iron, nickel
Plate that Africa is on
African Plate
A theory explaining the structure of the earth's crust and many associated phenomena as resulting from the interaction of rigid lithospheric plates that move slowly over the underlying mantle.
Plate Tectonics
Where are plate tectonics located on Earth
Everywhere at the surface, all over the surface of Earth
What occurs at all tectonic plate boundaries?
Earthquakes
Two types of crust
Oceanic and Continental
The plate that is off the west coast of South America
Nazca Plate
The lithosphere is broken up into
Tectonic Plates
When and how would you describe the movement of tectonic plates
Constantly, all the time and SLOWLY
Does Florida experience earthquakes and volcanoes due to tectonic plate movement
NO
The 3 types of plate boundaries
convergent, divergent, transform
Plate in Antarctica
Antarctic Plate
The tectonic plates of the lithosphere float slowly on the
asthenosphere
Yes or No: Can plate tectonic movement be predicted, do we know the directions of movements?
Yes
Sea Floor Spreading occurs under the ocean water at what type of plate boundary?
Divergent at mid ocean ridges
Evidence of Continental Drift Theory
Fossil Evidence
Climate change evidence, tropical plant fossils found in Antarctica
puzzle piece fit of the continents
Rock formations and layers are the same but moved apart
Mountain Chains that use to be connected
Glacial Striations (Grooves)
Plate that has the largest ocean in the world
Pacific Plate
What discovery led to the "how" that Alfred Wegener was missing when he released his Theory of Continental Drift?
Sea Floor Spreading at mid ocean ridges
True or False: Tectonic plates move many meters per year
False 1-2 inches
Subduction of a denser plate under a less dense plate happens at (?) plate boundaries and the melted magma will be released at near by volcanoes
Convergent
Who first suggested the theory of continental drift in 1912?
Alfred Wegener
Plate between North and South America
Caribbean plate
Plate Tectonic Movements are generated by the movement of what in what layer of Earth
Convection currents in the mantle
What causes earthquakes to happen at convergent and divergent plate boundaries
magma moving upward
What major land feature is formed at continental to continental convergent plate boundaries
mountains like the Himalayans where Mt. Everest is located.
