100
This volcanoe has a large surface area and is mostly flat.
What is a sheild volcanoe?
100
This plate is the densest, but the thinnest.
What is an ocean plate?
100
In this boundary, you can find subduction zones.
What is a convergent boundary?
100
Along this sea boundry, you can find mid ocean ridges.
What is a divergent boundary?
100
This is the densest and hottest layer.
What is the inner core?
200
This type of lava comes out of a cone volcanoe.
What is bassalt tephra or scoria?
200
this force is what causes most ovean plates to move.
What is ridge push or slab pull?
200
This boundry forms the Himilayan Mountains.
What is a convergent boundry.
200
This happens as the layers get closer to the center of earth.
What is getting hotter and denser?
300
These two volcanoes are formed at convergent boundries.
What are cinder cone and compsite volcanoes?
300
This force in the mantle moves the plates atop them.
What are convection currents?
300
This boundry is not creating or destroying any new crust.
What is a transfrom boundry?
300
This is where new floor and volcanoes are formed in the oceans.
What is a convergent boundry and mid ocean ridges?
300
The layers of crust and uppermost mantle make up this layer.
What is the lithosphere.
400
This volcanoe has the largest eruptions.
What is a composite volcanoe?
400
This is what the early model of Earth was called.
What is Pangea?
400
These boundries form the Ring of Fire.
What are Convergent boundries?
400
this is the youngest type of crust, because it is constantly being destroyed.
What is Ocean floor crust?
400
This is the only liquid layer.
What is the outer mantle?
500
This volcanoe produces mostly rhyolitic lava.
What is a composite volcanoe?
500
These are some of the reasons to bvelieve the continents were one at the begining.
What are fossils, climate similarities, continental fit, or terrain similarities?
500
This boundry is causing South Africa to "drift" away from the other part of Africa.
What is a rift or divergent boundry?
500
This is the reason humans can't dive down to explore the sea floor.
What is excessive pressure increase?
500
This layer may differ in density or depth depending on where it is measured.
