the layer of rock that forms the Eath's outer skin
What is the crust?
100
the hypothesis that the continents slowly move across Earth's surface
What is continental drift?
100
A section of the lithosphere that slowly moves over the asthenosphere, carrying pieces of continental and oceanic crust
What is a plate?
100
a force that acts on a rock to change its form or volume
What is stress?
100
a weak spot in the crust where molten material, or magma, comes to the surface
What is a volcano?
200
a layer of hot rock under the crust
What is the mantle?
200
the name of a single land mass that broke apart 200 million years ago and gave rise to today's continents
What is Pangea?
200
explains the formation, movement, and subduction of Earth's plates
What is the theory of plate tectonics?
200
stress that pushes a mass of rock in two opposite directions
What is shearing?
200
a major volcanic belt formed by many volcanoes that rim the Pacific Ocean
What is the Ring of Fire?
300
a sublayer that is made up of the crust and the upper mantle
What is the lithosphere?
300
the scientist who thought of continental drift
Who is Alfred Wegener? (last name only is acceptable)
300
breaks in the Earth's crust where rocks have slipped past each other
What is a fault?
300
Normal, Reverse and Strike-Slip are all types of these
What are faults?
300
an area where material from deep within the mantle rises and then melts, forming magma
What is a hot spot?
400
the inner most part of the Earth
What is the core?
400
three ways that Wegener tried to prove continental rift
(you need to name all three ways)
What is evidence from land features, fossils and climate?
400
when plates move apart or "diverge"
What is a divergent boundary?
400
the point on the surface directly above the focus of an earthquake
What is the epicenter?
400
a wide, gently sloping mountain made of layers of lava and formed by quiet eruptions.
What is a shield volcano?
500
the movement of liquid metals from the outer core create this
What is Earth's magnetic field?
500
any trace of an ancient organism that has been preserved in rock
What is a fossil?
500
a place where two plates slip past each other, moving in opposite directions
What is a transform boundary?
500
***DAILY DOUBLE*** How much will you wager?
It carries energy from an earthquake away from the focus, through Earth's interior, and across the surface.
What is a seismic wave?
500
a steep, cone-shaped hill or small mountain made of volcanic ash, cinders, and bombs piled up around a volcano's opening
