Layers of the earth
Below the crust; has 3 parts-upper, middle, and lower; largest layer; made of mostly silica, iron and magnesium.
What makes up the mantle?
To move around an axis inside the object (internal axis); the axis can be real or imaginary.
Describe rotating.
The measure of the energy released during an earthquake.
What is magnitude?
The block of rock that forms the upper half of a fault.
What is a hanging wall?
Effects on convergent bounders because of compression.
What causes Mountain building, subduction and Earthquakes?
The very deepest part of the Earth; in a solid state, due to pressure; made of iron and nickel.
What is the inner core?
To move around an axis outside the object (external axis); the axis can be real or imaginary.
Describe revolving.
A type of seismic wave that moves the crust below the surface up and down or side to side.
What is a S-wave?
The block of rock that forms the lower half of a fault.
What is a foot wall?
Stress that squeezes rock until it folds or breaks
What is Compression?
The outer portion of the core of the Earth; in a liquid state; made of iron and nickel.
What is the outer core?
the separation of Earth's interior materials based on density.
What is differentiation?
The point on the Earth's surface directly above where the rock breaks below the surface causing an earthquake.
What is the epicenter?
A type of fault where the hanging wall slides downward; caused by tension in the crust.
What is a normal fault?
Stress that moves rock in two opposite, horizontal directions.
What is shearing
Middle mantle; flows like hot asphalt; reason the crustal plates move (convection currents).
What makes up the asthenosphere?
The amount of mass in a given space; mass per unit volume.
What is density?
The point beneath Earth's surface where rock breaks under stress and causes an earthquake.
What is the focus?
A type of fault where the hanging wall slides upward; caused by compression in the crust.
What is a reverse fault?
Stress that stretches rock so that it becomes thinner in the middle.
What is tension?
Consists of the earth's crust and the upper mantle.
What makes up the lithosphere?
The transfer of heat by movement of a fluid.
What is convection?
A type of seismic wave that compresses and expands the crust below the surface in a straight line motion.
What is a P-wave?
A type of fault where rocks on either side moves in opposite, horizontal directions.
What is a strike-slip fault?
Effects on Divergent bounders because of Tension.
What causes earthquakes, seafloor spreading and, rift valleys.
