Layers of the Earth
There are _______(#) layers of the Earth.
What is six?
Places where tectonic plates meet.
What is a boundary?
Tectonic Plates move at this speed.
What is 0.6-10cm per year?
Transform faults occur at this boundary
What is a transform boundary?
The liquid layer of the Earth found below the Mantle. Made of liquid iron and nickel.
A block of lithosphere that consists of the crust and the rigid, outermost part of the mantle. HINT: They move.
What is a tectonic plate?
The boundary formed by the collision of two tectonic plates.
What is a convergent boundary?
_________________ are a result from the build up of stress at a transform boundary.
What are earthquakes?
A force that acts on a rock to change its shape or volume.
What is stress?
Although the hottest layer of the Earth, this layer is solid metal.
What is the inner core?
This theory describes how fast plates move and states that plate movement affects many geologic structures and processes
What is the theory of plate tectonics?
The boundary between two tectonic plates that are moving away from each other.
What is a divergent boundary?
The occurs between two tectonic plates that are scraping past each other horizontally and rocks begin breaking
What is a fault?
This is a very active area for earthquakes and volcanoes.
What is the Ring of Fire?
This layer of the Earth has an inner and outer layer of solid rock with a layer of melted (molten) rock in between.
What is the Mantle?
The Earth's crust is composed of this many tectonic plates
What are 8 main plates and many smaller plates?
The boundary where two plates slide past each other
What are transform boundaries?
The term that describes the downward bending of rock during a fold
What is a syncline?
The difference between a fold and a fault.
Fault = Breaking
The name of the layer that is composed of the upper mantle
What is the astenosphere?
This is the name of the scientist that first published the idea of plate movement
Who is Antonio Snider-Pellegrini?
This is an area that occurs at convergent boundaries when one plate sinks and one plate gets pushed up
What is a subduction zone?
These two landforms are created at subduction zones
What is a trench and a volcano/mountain.
These are the four types of mountains
What is volcanic, domed, folded, and fault-block?
