Crust,Core, or Mantle
This has an oceanic and continental part
Crust
What type of evidence was used to support the idea of continental drift?
Fossils and/or rock layers in mountains
Name the three types of plate boundaries
Convergent
Divergent
Transform
deformation
What type of fault is the San Andreas Fault?
Strike-slip fault
This is made of mostly iron and nickle
Core
What was the name of the single huge continent that existed about 245 million years ago?
Pangea
These tectonic boundaries push towards each other
Convergent
When rock layers are folded so that both ends of the fold are horizontal
Monocline
What is it called when a oceanic crust is sliding underneath a continental crust
Subduction
This has an inner and outer portion
Core
These travel at different speeds through the Earth which allowed scientists to identify the layers of the Earth.
Seismic waves
These tectonic boundaries push away from each other
Divergent
When rocks form upward-arching folds (like the hump on a camel).
Anticlines
What types of features are found near tectonic plates?
Mountain ranges, volcanos, earthquakes
This is where the asthenosphere is
Mantle
These are pieces of lithosphere that move around on top of the asthenosphere
Tectonic plates
These tectonic boundaries slide horizontally past each other
Transform
When the hanging wall is moved down relative to the foot wall.
Normal fault
What type of scientist studies seismic waves?
Seismologists (size - moll - O - gists)
This is where we believe there are convection currents
Mantle
Pacific, Nazca, Australian, and North American are all examples of
Different tectonic plates
The mid ocean ridge (the mountain range in the Atlantic ocean) is an example of this type of boundary
Divergent
When rocks are pushed together and the hanging wall is pushed up compared to the foot wall.
Reverse fault
What evidence was used to prove sea-floor spreading is happening?
Changes in the direction of magnetic minerals in the ocean floor.
