Earth
Which Layer of the Earth is described as the outermost layer, composes less than 1% of Earth’s mass, and is 5-100 km thick
crust
The Earth is composed of numerous rigid plates that move and interact along boundaries. This is known as
Plate Tectonics
A plate boundary in which plates move away from each other due to heat upwelling is
Divergent
area where sea-floor spreading takes place
mid-ocean ridges
the bending of rock layers due to stress
folding
Which layer of the Earth is described as being the center of the Earth, consists of 33% of Earth’s mass
Core
Plates move due to heat flow produced by
Geothermal meltdown
two plates collide at what boundary?
convergent boundary
Hanging wall moves down relative to footwall
The process by which the shape of a rock changes because of stress is
deformation
The solid, outer layer of the Earth that consists of the crust and rigid upper part of the mantle is the
lithosphere
The idea that states the continents once formed a single landmass, broke up, and drifted to their present locations is called
where two plates are moving horizontally past each other
transform boundary
hanging wall moves up relative to footwall
reverse fault
An arch shaped fold
anticline
The solid, dense center of the planet is the
Inner Core
process of Earth's magnetic poles changing places
magnetic reversal
sets of deep cracks that form between two tectonic plates that are pulling away from each other
rift zones
What is stress that occurs when forces act to stretch an object?
tension
fold where both ends of the rock layer are horizontal
monocline
How can the deep interior of the Earth be mapped?
Seismic waves
The process by which new oceanic lithosphere forms as magma rises toward the surface and solidifies is called
Sea Floor Spreading
One plate is less dense so the lighter one overrides the other
Subduction zone
Name one other fault other than reverse and normal
strike-slip
transform
a downward troughlike fold
syncline
