Earth Layers
This layer contains the continental and oceanic crust
Lithosphere
associated with, or form, the boundaries between Earth's tectonic plates
Faults
the shaking of the surface of the Earth
Earthquake
The physical disintegration and chemical decomposition of earth materials
Weathering
a detailed description or representation on a map of the natural and artificial features of an area
Topography
This layer takes up 84% of the earths volume
Mesosphere
plates moving away and a new crust forming
Plate Boundaries
gradual movement of the continents across the earth's surface
Continental Drift
Any of the various weathering processes that cause physical disintegration of exposed rock
Mechanical Weathering
a line on a map joining points of equal height above or below sea level
Contour Lines
This layer is completely solid rock
Asthenosphere
A tectonic boundary where two plates are moving toward each other
Convergent Boundaries
the formation of new areas of oceanic crust, which occurs through the up welling of magma
Sea Floor Spreading
The erosion or disintegration of rocks
Chemical Weathering
A map marked with contour lines
Contour Map
This is the only liquid layer made up of nickel,iron and other metals
Outer core
Where two plates are moving away from each other and new crust is forming from magma that rises to the Earth's surface
Divergent boundary
a long, seismically active submarine ridge system situated in the middle of an ocean basin
Mid-Ocean Ridge
A fold of rock layers that slope upward on both sides of a common low point
Syncline
a change in the Earth's magnetic field resulting in the magnetic north being aligned with the geographic south, and the magnetic south being aligned with the geographic north
Magnetic reversals
This is the hottest layer of the earth
Inner core
Places where plates slide sideways past each other
Transform Boundary
the process of plate tectonics separated
Pangea
A fold of rock layers that slope downward on both sides of a common crest
Anticline
associated with, or form, the boundaries between Earth's tectonic plates
Faults
