Radiation
|
The transfer of heat in the form of electromanetic waves
|
The tranfer of heat by moving air
|
Convection
|
Conduction
|
The transfer of heat through a solid metal
|
Convetion Currents
|
The transfer of heat by the mass movement of heated particles into an area of cooler fluid
|
Direct Evidence
|
evidence of a witness who testifies to the truth of the fact to be proved (contrasted with circumstantial evidence ).
|
Indirect Evidence
|
Proof of facts offered as evidence from which other facts are to be inferred
|

Lithosphere
|
The Lithosphere is solid and rigid. It is the uppermost part of the mantle.
|
Asthenosphere
|
The Asthenosphere is below the Lithosphere. t is less rigid then the Lithosphere and it can bend like a spoon, but it's still rock solid.
|
Mesosphere
|
The Mesosphere is at the bottom of the mantle. It has high pressure. It's hot and rigid.
|
Outer Core
|
The outer core is a layer of liquid molten metal surrounding the inner core.
|
Inner core
|
The inner core is a dense ball of solid metal.
|
Continental Crust
|
It formed the continents. It contains many different types of rocks. It is much like Granite.
|
Oceananic Crust
|
It's the crust that lies beneath the ocean. It's overall composition is like Basalt with small amounts of ocean sediment on the top.
