Journey to the Center of the Earth
Thinnest layer
Crust
What type of evidence came from rocks and mountains found on different continents?
Geological evidence
Type of plate boundary where two plates move towards each other
Covergent
Formed from convergent boundaries (continental crust to continental crust)
Mountains
Source of heat for convection cycles in the Earth
Earth's hot interior (or more specifically outer and inner core)
Biggest layer
Mantle
Evidence from different plant and animal remains found on different continents.
Fossil Evidence
Type of plate movement where two plates slide past one another
Transform
Divergent plates in the ocean typically create this.
Seafloor spreading, underwater volcanoes, mid oceanic ridge, etc
Mountain range in the middle of the ocean where two oceanic plates separate
Mid-oceanic ridge
Where convection mostly occurs
Mantle
On what plate is Eugenia B Thomas located on?
North American Plate
Plates that move away from each other
Divergent
Transform plates typically cause this
Earthquakes
What two things increase as we go deeper into the Earth?
Pressure and Temperature
Two types of crust are ____
continental and oceanic
Why was continental drift theory not accepted?
Did not explain how the continents moved
What drives (creates) plate motion?
Convection cycle
Usually created by convergent plate boundaries between oceanic and continental crust.
Volcanoes
Only liquid layer of the Earth
Outer Core
The inner core is mostly composed of _____.
Iron
One good thing that came from people's skepticism of Plate tectonic theory was _______
Describe what happens in the convection cycle in your own words
Hot, less dense material rises and cold, more dense material sinks over and over
Why are there so many earthquakes and volcanoes along the Ring of Fire?
It is located on plate boundaries or borders
Name of the area where one plate slides under another one, typically causing volcanic activity
