Convection Currents and the Mantle

3 Types of Heat transfer

• Radiation- transfer of heat through empty space

• Conduction- transfer of heat by direct contact

• Convection- transfer of heat involving the movement of fluids-liquids and gases

The DEEPER you go inside the earth, the GREATER the TEMPERATURE becomes

Lithosphere and Asthenosphere

Lithosphere: Rigid surface shell that includes upper mantle and crust ( here is where "Plate tectonics" work), cool layer

​

Asthenosphere​: Layer below the Lithosphere, part of the mantle, weak and deformable (Can be reshaped). This layer deforms as plates move, partially melting of the material happens here. (Deeper so this layer is getting hotter in temperature).

Some text here about the topic of discussion

Asthenosphere

• Heat from Earth’s core and mantle cause hot columns of mantle material to rise

• Hot material spreads and forces the cooler material to sink 

Density

A measure of how much mass there is in a volume of a substance.

​

m/V=p​

Quick review of Mass and Volume

• Volume- amount of space something takes up

• Mass- amount of matter in an object

Therefore...

• Mass- how heavy/full something is

• Volume- how much space it takes up
