Earthly parts
Not the plates you eat from
Know your boundaries
Collision Course
It's all about the plates
100
The part of the Earth that is a ball of hot, solid metals.
What is the inner core
100
many large and small slabs of rock that include both continental crust and oceanic crust.
What is (are) tectonic plates
100
Most are found in the oceans.....these are boundaries that occur where plates move apart
What is/are divergent boundaries
100
Occurs when one plate sinks beneath another
What is subduction
100
In what direction do plates move in transform boundaries?
What is horizonally
200
Part of the Earth that is less dense near the crust more dense near the core.
What is the mantel?
200
Comes from Greek word meaning "all lands" ...a once huge supercontinent
What is the Pangaea
200
These boundaries occur where plates push together
What is convergent boundaries
200
Mountains are formed when two _______________ plates push together
What is continental plates
200
Give two proofs that continental drift occured since the pangaea
What is discovery of like fossils and rocks on different continents.
300
The hotter, softer layer of rock on which the lithosphere rests
What is the asthenosphere.
300
Energy transfered by the movement of material
What is convection
300
These occur where plates scrape past each other
What are transform boundaries
300
In oceanic-oceanic subduction the older plate sinks because it is ______________ and _____________ than the younger plate.
What is cooler and denser
300
Earth's thickest layer
What is the mantle
400
The Earth's crust is the thinnest ........
What is under the oceans
400
In the asthensophere, heated rock constantly rises, cools, sinks and is heated again. ________________ current
What is convection current.
400
Continents split apart at __________ boundaries
What is divergent
400
As ocean crust moves it often causes underwater _____________________
What are earthquakes
400
What is the thin layer of cool rock that surrounds the Earth sort of like an egg shell
What is the crust
500
This layer remains liquid and is heated to about 4400-6100 degrees C
What is the inner core?
500
Earth's _______________________ is made up of moving plates.
What is the lithosphere
500
Volcanic actrivity that develops above a plume, which is a stream of magma rising from the mantle.....they offer a way to measure plate movement.
What are hot spots
500
The largest transform boundary in the US
What is the San Andreas fault
500
This is the name of the scientist who came up with the hypothesis of continental drift.
Who is Alfred Wegener
