Name the two types of earth's crust
continental and oceanic
What is the plate in Africa called
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 tectonic plates located
All around the world
What can plate tectonics cause at transform boundaries?
Earthquakes
What is the longest continuous mountain chain on earth?
Mid- ocean (Mid-Atlantic) Ridge
What is the plate in Europe called
European Plates
True or false, Tectonic plates are always moving
True
How many tectonic plate boundaries are there in Australia?
0
Name the 3 types of plate boundaries
convergent, divergent, transform
What is the plate in Antarctica called
Antarctic Plate
How many major plate tectonics are there?
7
Name 2 pieces of evidence that scientists use to justify the plate tectonic theory
Fossil similarities between continents
Matching rock formations across continents
Climate evidence of past glacier activity
What is the plate in Eastern Europe called
Eurasion Plate
The driving force behind plate tectonics
Convection
T/F plate tectonics move several feet per year
False
Who first suggested the theory of continental drift?
Alfred Wegener
What is the plate in America called
American Plate
Plate Tectonic Movements are generated by the movement of what?
Convection currents in the mantle
What causes Plate tectonics to move?
Convection currents in the mantle
The area around the Pacific Ocean where there are many volcanoes and extensive seismic activity
What is the Ring of Fire?
What is Pangaea?
as new crust is created at a mid-ocean ridge magnetic rocks are deposited. Over time as the poles reverse, these rocks will change their direction
these are considered constructive zones where crust is created
What are divergent boundaries or mid-ocean ridges?
What is a tsunami?
these are found around transform faults and are large expansive areas of seafloor
What are abyssal plains?
