• Continental crust
• Mountain Ranges
• Plate Tectonics

• lithosphere
• asthenosphere
• hydrosphere
• Atmosphere

NGSS.5-ESS2-1

What is the upper layer of Earth's mantle that bends like plastic?

• lithosphere
• asthenosphere
• atmosphere
• hydrosphere

What do scientists study about seismic waves to determine the structure of the Earth?

• speed
• path
• direction
• All of these

What happens to the temperature and pressure as you go deeper into Earth?

• They both decrease
• They both increase
• Temp. increases and pressure decreases
• Temp decreases and pressure increases

What is the inner core made of?

• solid iron and nickel
• liquid wood
• gasses
• liquid iron and nickel

What is the Earth's outer core made of?

• liquid iron and nickel
• solid iron and nickel
• gasses
• solid wood

Heat from the core makes material in the mantle rise up, then when it cools it falls back down and this is called a convection current. 

• True
• False

Why does the core produce heat?

• radioactive elements in the core decay and produce heat
• Melting produces heat
• convection currents
• radioactive isotopes are formed

In terms of seismic waves, what is a "shadow zone"?

• a specific spot inside Earth where waves can't reach
• It is very dark there
• A place where waves can go where ever they want
• There is no such thing as a "shadow zone"
