Layers of the Earth
The innermost layer of the earth.
What is the inner core.
Boundaries where tectonic plates move towards each other.
What is convergent?
This type of rock is formed when lava/magma cools and hardens.
What is igneous?
The area around the Pacific Ocean where many tectonic events occur.
This scientist came up with the Theory of Continental Drift.
Who is Alfred Wegner?
The outermost layer of the earth.
What is the crust?
Boundaries where plates move away from each other.
What is divergent?
This type of rock is formed when heat and pressure cause one kind of rock to change into a different kind of rock.
What is metamorphic?
A major tectonic event that took place in the US in 1980.
What is the eruption of Mount St Helens?
Wegner used this as his first piece of evidence for his Theory of Continental Drift when he looked at a world map?
What is the continents look like puzzle pieces?
The layer directly under the crust.
What is the mantle?
Boundaries where plates slide past one another.
This changes igneous and metamorphic rocks to sedimentary rocks.
What are weathering and erosion?
Officials might do this to lessen the effects of the catastrophic event if they knew a volcano was close to erupting.
What is alert the public, monitor the site, or evacuate the area>?
Wegner used this as his second piece of evidence for his Theory of Continental Drift.
What are Mesosarus fossils in both South America and Africa?
The layer between the mantle and the inner core.
What is the outer core?
What are divergent boundaries?
These two things cause sedimentary and igneous rocks to change into metamorphic rocks.
What are heat and pressure?
Based on data from previous tectonic events, humans have used technology to lessen the effects by doing this.
What is creating earthquake proof buildings/bridges or sending out mass alerts to cell phones.
The name of the large land mass Wegner said must have existed millions of years ago if his Theory of Continental Drift is correct.
What is Pangaea?
The two parts of the mantle.
What are the lithosphere and the asthenosphere?
These type of boundaries create mountain ranges and volcanoes.
What are convergent boundaries?
This causes sedimentary and metamorphic rocks to change into igneous rocks.
What is melting?
This singer recorded the song "Ring of Fire."
Who is Johnny Cash?
In modern vernacular, what most other scientists thought about Wegner's Theory of Continental Drift.
What is "That's cap!"
