|
Inner Core |
The sphere of solid Nickel and Iron at the center of Earth; surrounded by the liquid outer core |
|
|
Outer Core |
The outer layer of Earth's core; surrounds the inner core and is made of liquid nickel and iron |
|
|
Mantle |
the solid layer of Earth between the crust an the core; made of dense silicates |
|
|
Crust |
The thin, solid outermost layer of Earth; made of less dense silicates and is either continental (landmasses) or oceanic (ocean floors) |
|
|
Lithosphere |
The cool, rigid, outermost layer of Earth that consists of the crust and the uppermost part of the mantle; broken into pieces or segments called plates |
|
|
Asthenosphere |
The solid layer with plasticity in the upper mantle that is located just below the lithosphere; lithospheric plates "float" and move on this layer |
|
|
Plasticity |
a characteristic of the material in the asthenosphere; existing in a solid state yet having the ability to flow without being a liquid |
|
|
Earth's layers |
the division of the composition of Earth determined by either chemical composition or by the physical state of matter |
|
|
Chemical composition |
the types, quantities, and arrangements of elements that make up a substance |
|
|
Physical Properties |
Measurable characteristics that describe the physical state of something, including mass, magnetism, temperature, density, shape, volume and conductivity` |
|
|
Temperature |
a measure of the amount of heat energy |
|
|
States of Matter |
Distinct forms of matter known in everyday experience: solid, liquid, and gas; also referred to as phases of matter |
|
|
Pressure |
force exerted on matter through contact with other matter; affects melting and boiling points |
|
|
Density |
the amount of matter in a given space or volume; it is a relationship between mass and volume. Less dense matter will form layers above dense matter. |
