EARTH STRUCTURE AND HEAT TRANSFER
RADIATION
Radiation is the transfer of heat transferred through electromagnetic waves.
This type of heat transfer can be observed on sunny days.
Most electromagnetic radiation form the sun is in the form of visible light.
FUN FACT These frequencies are interpreted by our brain as
colors.
CONDUCTION Is the transfer of heat from one molecule
to another within a substance.
When heat is transferred through conduction it flows from warmer to cooler regions and will transfer more rapidly with greater temperature differences.
CONVECTION
Is the transfer of heat through the movement of a fluid.
Convection transfers heat vertically into the atmosphere.
CONVECTION CONTINUED
Convection is due to the sun heating Earth.
The heat absorbs water shown by when there is a drought the water dries up and ground is cracked.
ENERGY BY THE SUN
Energy from the sun will effect the ocean tide.
Also the moon has an effect on the tide and gets its light from the sun.
EARTH LAYERS
CRUST LITHOSPHERE ASTHENOSPHERE MANTLE OUTER CORE INNER CORE
CRUST
The thin outer layer
of the earth is
where we live.
The continental crust is made up of rocks that consist primarily of silica and alumina called the ‘sail”
Mantle is much thicker than the Crust, it is three thousand kilometers deep.
It is made up of slightly different rocks with a lot more magnesium and iron
MANTLE
Magnesium has 12 protons and 12 neutrons
Iron has 26 protons and 30 neutrons
OUTER CORE
The earths outer core is made up of iron and nickel.
it is very hot in the outer core. Ranging from 4400 to 5000+ degrees
Celsius.
INNER CORE
The earths inner core is made up of iron and nickel.
It is under immense pressure.
So much pressure, that even though it is so hot, it is solid.
QUESTIONS CHRIS
What is the very inside of the earth?
What is the transfer of heat through electromagnetic waves?
QUESTIONS LIAM
What is the definition of convection? How does the air transfer energy from one
region to another?
