Fun Facts
What generates from a transform boundary/
an earthquake
Thinnest layer and holds the land and oceans.
crust
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 tectonic plates located?
Everywhere in the crust
What can plate tectonics cause?
Earthquakes
What forms at a continent-continent convergent boundary?
mountains
The thickest layer that is often broken into upper and lower; molten lava
mantle
The lithosphere (crust) is broken up into
Tectonic Plates
At an ocean-continent convergent boundary, which plate will always go under the other?
Oceanic will always go under continental
How many boundaries are there including sub-types?
6
3 types of plate boundaries
convergent, divergent, transform
This layer is the liquid layer below the mantle and is responsible for generating Earth's magnetic field.
outer core
What are the two types of tectonic plates; meaning what do they hold?
oceanic and continental
Can plate tectonic movement be predicted?
Yes
What are the three types of convergent boundaries?
ocean-ocean
ocean-continent
continent-continent
What forms at a divergent boundary in the ocean?
ocean ridges
This is the solid most inner layer of the Earth and is mainly iron and nickel
inner core
Why do tectonic plates not sink into the mantle except at the subduction zone?
They are less dense than the mantle
T/F tectonic plates move constantly
true
What is it called when one plate sinks under another and recycles itself in the mantle?
subduction
How many different plates are there?
2
In which layer does convection occur?
mantle
Plate Tectonic Movements are generated by the rotation of the globe and the tidal forces of the ?
Sun and Moon
What causes Plate tectonics to move?
Magna flowing beneath the Earth/ convection
Describe what convection is.
At the subduction zone the crust sinks into the mantle where it is reheated and rises to the surface again creating a current in the mantle.
