What is the correct order (starting from the surface) of Earth's layers?

• crust, mantle, outer core, inner core

• inner core, outer core, mantle, crust

• crust, inner core, outer core, mantle

• crust, mantle, inner core, outer core

The transfer of energy through empty space is called

• radiation

• conduction

• convection

• magic

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

• layers

• continents

• ridges

• trenches

Which of Earth's layers is the thickest?

• mantle

• crust

• inner core

• outer core

Which part of Earth contains most of it's mass?

• geosphere

• atmosphere

• biosphere

• hydrosphere

Earth's inner core is

• a dense ball of solid metal

• a layer of molten metal

• hot rock

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

Particles of a hot soup rise slowly on a pot simmering on a stove. As the hot soup nears the surface it begins to cool. The cooler soup sinks, forming a constant movement of soup that moves energy towards the surface of the pot. The constant movement of soup in the pot is called a __________.

• convection current

• radiation

• conduction current

• magnetic field
