100
I am another name for Earth's crust.
What is Lithosphere?
100
Tectonic Plate movement is recorded in this unit of measurement.
What is Centimeters?
100
This famous scientist is known for his theory on Continental Drift.
Who is Alfred Wegener?
100
Mountain ranges mainly form at this type of boundary.
What is Convergent?
100
Oceanic lithosphere sinks under this type of crust.
What is Continental?
200
Tectonic plates, or lithosphere, float on top of this layer.
What is Asthenosphere?
200
Scientists measure tectonic plate movement using this special equipment.
What is GPS or Sonar?
200
I am the driving force causing Earth's lithosphere to move.
What is Heat?
200
This type of boundary is formed during a Mid – Ocean Ridge.
What is Divergent?
200
What are three boundary types?
What is Convergent, Divergent, and Transform?
300
Earth is covered by lithosphere and is divided into boundaries called
What is Tectonic Plates?
300
This type of crust is more dense and the heaviest.
What is Oceanic?
300
The oceanic lithosphere slides downhill due to gravity during this process.
What is Ridge Push?
300
Earthquakes form at this type of boundary.
What is Transform?
300
Oceanic lithosphere subducts or sinks under continental lithosphere because oceanic lithosphere is more ___________.
What is Dense?
400
Without this layer, a magnetic compass would not work.
What is Inner Core?
400
This type of crust is the thickest yet lightest.
What is Continental?
400
Warm magma rises to the surface while cold lithosphere sinks at subduction zones during this process.
What is Convection?
400
When plates collide, divide, slide, or allow a hot spot to form, this type of landform can result.
What is Volcano?
400
This process occurs when oceanic crust collides with continental crust.
What is Subduction?
500
The inner core is comprised of these two liquid metals.
What is Iron and Nickel?
500
The name of this Tectonic Plate includes both Continental and Oceanic crust.
What is the South American Plate?
500
The denser side of a plate sinks and pulls the rest of the plate deeper underground during this process.
What is Slab Pull?
500
Sea floor spreads when magma rises and solidifies forming young oceanic lithosphere in this landform.
What is Mid - Ocean Ridge?
500
Name three evidences to support the theory of Continental Drift.
