BONUS 100 pts- What is the the sphere we call the crust?
the crust
BONUS: The lithosphere
In this type of boundary, plates slide against each other
transform plate boundaries
What is the name of the theory that states the earth's crust is made of large sections moving over the mantle.
Plate Tectonics
Where do tectonic plates interact?
at their boundaries
What lies directly beneath the crust
the mantle
What is the liquid part of the earth called
the outer core
What is the most inner solid layer of the earth
the core
Which plates move Side to Side?
Transform
Magma is inside.
Lava is outside.
Earthquakes happen because of
transform boundaries sliding past eachother
How do you make underwater volcanoes
Old oceanic plate boundaries go under New oceanic plate boundaries
What comes out of earth's volcanoes
Lava
When ocean and ocean collide, which one SINKS under the other?
Older sinks under Newer
Transform boundaries create this
earthquakes and fault lines
Divergent plate boundaries create this under water
sea floor spreading
cracks in the earth where plates slide against one another
fault lines
When a plate sinks under another
subduction
