Layers of the Earth
This layer of the Earth is made of MOVABLE SOFT ROCK that moves in cycles
What is Asthenosphere?
One piece of evidence that supports the idea that the continents began as just ONE landmass and then SEPARATED into multiple continents (Think of Pangea map)
What are similar landforms/fossils that fit together like a puzzle?
The Mid-Ocean Ridge is formed along this kind of boundary
What is a divergent boundary?
The place where two plates move TOWARDS each other
What is a convergent boundary?
This most likely causes Earth's inner core to be a solid
What is the pressure at the core is very high?
This layer of the Earth is made of SOLID IRON and NICKEL
What is the inner core?
There is a lot of evidence to support the Theory of Plate Tectonics. Describe one piece of evidence that proves that plates are ACTIVE today (think of natural disasters)
What is an earthquake/volcano
True or False: Oceanic crust NEAR the mid-ocean ridge is YOUNGER than oceanic crust away from the ridge
What is true?
A SPECIFIC place on Earth where there is a DIVERGENT boundary
What is the African Rift Valley?
The order of Earth's layers starting from the INSIDE of the Earth
What is: INNER core, outer core, mantle, crust
This layer of the Earth is part of the upper mantle and crust; it is made of hard pieces of rock that fit together as PLATES
What is the lithosphere?
The process by which an oceanic plate SINKS BENEATH a continental plate
What is subduction?
True or False: The MID-OCEAN RIDGE occurs along a TRANSFORM boundary
What is False? (Earthquake)
The reason why there are so many more earthquakes in California than there are in New England (Hint: a SPECIFIC place on Earth where there is a TRANSFORM boundary)
What is the San Andreas Fault Line is in California?
True or False: The outermost layer of the Earth is called the MANTLE
What is false? (Crust)
This layer of the Earth is a THIN and DENSE layer of rock (type of crust)
What is oceanic crust?
True or False: The tectonic plates are still moving today
What is true?
True or False: Since The Atlantic Ocean is getting WIDER every day; the Earth is getting bigger
What is false? (As the oceans get bigger, the amount of land gets smaller)
A SPECIFIC place on Earth where plates collide and form JUST mountains
What is the Himalayas?
The two types of land forms that may be created during subduction
What are a trench or a volcano?
This layer of Earth is LESS dense - it makes up LAND masses (a type of crust)
What is continental crust?
This is created when one plate moves under another
What is a trench?
Where the NEW crust is formed on the Earth
What is the mid-ocean ridge?
The two types of crust that collide causing subduction (when one crust goes under the other)
What is oceanic crust and continental crust?
The type of boundary that occurs when two plates PASS each other in opposite directions
What is a transform boundary?
