Convection & the Mantle

Holes drilled several kilometers into Earth's crust provide evidence about Earth's interior in the form of

• Seismic waves

• Rock samples

• Liquid iron

• Volcanic eruption

Geologist obtain indirect evidence about Earth's interior by

• Measuring pressure differences at Earth's surface

• Estimating temperature inside of Earth

• Directly looking under Earth's layers

• Recording and studying seismic waves

Earth's Inner Core is

• A dense ball of solid metal

• A layer of molten metal

• A layer of hot rock

• A layer of rock that forms Earth's outer skin

When you touch a hot pot or pan, energy moves from the pot to your hand

• Magnetic energy

• Indirect Evidence

• Subduction

• Heat Transfer

The transfer of energy through empty space

• Conduction

• Convection

• Radiation

• Subduction

Heat transfer within a fluid takes place by

• Convection currents

• Radiation

• Conduction

• Density

Most geologist think that the movement of Earth's plates are caused by

• Conduction

• Earthquakes

• Convection currents in the mantle

• Earth's magnetic field

Using data from seismic waves, geologist have learned that Earth's interior is made up of several

• Continents

• Layers

• Ridges

• Trenches

Earth's mantle is

• a layer of molten metal

• a layer of hot rock

• a dense ball of solid metal

• a layer of rock that forms Earth's outer skin

Earth's magnetic field result from movements in the

• Mantle

• Outer core

• Inner core

• Crust
