plates

100
Most mountains are formed in groups called these

About this number of earthquakes happen every year
What is one million?
100
in a quiet eruptions, this flows slowly out of the volcano
What is lava?
200

this layer is at the very center of Earth

inner core

200

The plates do this on the hot liquid rock of the mantle below them

rest

Dome-shaped mountains are usually these types of mountains
What is low?

A fault is the place where two of these meet
What is plates?
200
This type of volcanoes are formed when lava spreads out around the vent in a quiet eruption

What is toward each other, away from each other, orpast each other?

300
Mountains in a range have about the same of this
What is size?
300
When the plates move, the crust near this is squeezed and stretched

300
This type of volcano is formed when when a volcano erupts violently and throws cinders out the top
What is cinder cones?
400

This is the thickest layer of Earth

mantle

400
This is the longest mountain range in the world
What is Andes?
400
This is usually less than 25 miles below the surface
What is the focus?
400
This type of volcano is formed when cinders make up some layers and lava flows make up other layers
What is composite volcano?
500

This is the outer layer of Earth

crust

500
These are three of the major plates on Earth
What is Eurasian, the Africa, and The South American?
