3 Redistribution of the earth's heat
Conduction, Convection, Radiation
13
Heat transfer occurs between objects by direct contact
Conduction
14
Heat transfer where in the less dense or warmer rises and the cooler sinks
Convection
15
Heat transfer occurs through electromagnetic waves and force without involving particles
Radiation
16
This process occurs when solid materials such as rocks and minerals are melted due to an increase in temperature, pressure, and volatiles
Magmatism
17
3 special conditions required for the formation of magma
Temperature, Pressure, Volatiles
18
Where does magma form
Mid-ocean ridge, Mantle plumes (hot spot), Subduction zone
19
The rising magma in mantle convection cell brings heat to the surface, transferring heat to the overlying rocks.
Mid-ocean ridge
20
These work promoting the partial melting of rocks along the spreading center
Mid-ocean ridge
21
The source of heat for _______ is much deeper compared to mid- ocean ridges
Mantle plumes (hot spot)
22
The presence of water during generation results to the formation of hydrous or watery minerals, which when paired with the change in temperature and pressure conditions, brings about mineral instability, and the formation of the surrounding hot rocks into magma.
Subduction zone
