Convection & the Mantle

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

• Continents

• Layers

• Ridges

• Trenches

Earth's magnetic field results from movements in the

• Mantle

• Outer Core

• Inner Core

• Crust

Scientist think that convection currents flow in Earth's

• Mantle

• Outer Core

• Inner Core

• Crust

____________ occurs when heat is transferred into an object through motion or movement; an example would be boiling water.

• conduction
• convection
• radiation

NGSS.MS-PS3-4

____________ occurs when heat is transferred to an object through direct contact with particles; an example would be the heat from a stove transferring to your hand through the handle on a pot or pan.

The transfer of heat by the movement of heated fluid is called conduction.

• True
• False

Mantle material rises in convection currents because heated materials become more dense.

• True
• False
