Earths Layers
This is the thin, outermost layer of Earth, ranging from 6 to 70 km thick.
What is the crust?
This type of crust is thicker and less dense, usually made of granite.
Continental Crust
At this boundary, plates move apart and magma rises to create new crust.
What is a divergent boundary?
This is the term for one tectonic plate sinking beneath another.
What is subduction?
In the sea-floor spreading model, this substance rises between the crackers to mimic magma.
→ What is cool-whip?
How old is Mr. H?
26
This layer makes up 83% of Earth’s volume and lies beneath the crust.
What is the mantle?
This type of crust is thinner and denser, usually made of basalt.
What is oceanic crust?
This boundary occurs when plates collide, sometimes creating mountains.
What is a convergent boundary?
What type of boundary are the Himalayas?
Convergent boundary
During the transform boundary model, the cracking of the graham cracker represents this natural disaster.
→ What is an earthquake?
How tall is Mr. H?
6 ft
Made mostly of iron and nickel, this is Earth’s deepest and hottest layer.
What is the core?
When oceanic and continental crust collide, this crust subducts because of its greater density.
What is oceanic crust?
At this type of boundary, plates slide past each other horizontally.
What is a transform boundary?
When two continental plates converge, this giant landform is created.
→ What are mountains? (or What is a mountain range?)
In the convergent collision model, wetting the crackers helps simulate the bending and folding that forms these landforms.
→ What are mountains?
What was Mr. H job before teaching?
Head coaching A college program
This process at divergent boundaries creates new oceanic crust as magma rises between separating plates.
→ What is sea-floor spreading?
Sea-floor spreading forms new crust mainly between these two types of crust.
What are two oceanic plates?
The San Andreas Fault is an example of this type of boundary.
What is a transform boundary?
In a subduction zone, the plate that sinks is pushed into this layer of the Earth.
→ What is the mantle?
The graham crackers in the lab represent these large pieces of Earth’s lithosphere.
→ What are tectonic plates?
What Sport did Mr. H play in college?
