Layers of the Earth
This is the thin, outermost layer of the Earth where we live
Crust
Where 2 plates move away from each other
Divergent boundary
Paleomagnetism studies the magnetic material in...
Rocks
The crust is the thinnest layer of the Earth
True
This hot, thick layer lies just below the crust and moves slowly.
Mantle
Convergent Boundary
Seafloor spreading
Normal polarity points _____ and reversed polarity points ______
North, South
Convergent boundaries are where 2 plates move away from each other
False
Core
Where 2 plates slide past each other horizontally.
Transform boundary
This type of plate boundary creates a mid ocean ridge
Divergent boundary
The magnetic patterns on both sides of a mid ocean ridge provide evidence for this process
Seafloor spreading
New oceanic crust is created at mid ocean ridges
The movement of this semi-solid layer causes tectonic plates to move
Asthenosphere
Area where one plate slips under the other
Subduction Zone
Rocks closer to the mid ocean ridge are _______ and rocks farther away are ________
younger, older
When magnetic minerals in lava align with Earth's magnetic field, this is recorded
Polarity
Paleomagnetism provides evidence that the continents have NOT moved over time.
False
This type of crust is thick and more dense
Continental crust
The Andes and the Himalayas are a result of this type of boundary
Convergent boundary
The material that rises from the mantle to create new crust at a mid ocean ridge is called...
Magma
Theory that suggests that plates move.
Theory of plate tectonics
Cooler, Warmer
