Name the three layers of the mantle from top to bottom.
lithosphere, asthenosphere, lower mantle

Which statement is true....
1. Heat moves from a warmer area to a cooler area.
2. Heat moves from a cooler area to a warmer area.

When heat is removed from convection currents, what will eventually happen to them?
They will eventually stop.
Another name for earthquake waves.
seismic waves
What is the core mainly made of?
iron & nickel
How many dimples does the average golf ball have?
336
What happens to mantle material (magma) when it cools near the crust? Talk about the molecules
The molecules come closer together, become more dense and sink
Name 3 things needed for convection currents to happen?
temperature + density + gravity
Name the 7 layers of Earth
Inner Core, Outer Core, Lower Mantle, Asthenosphere, Upper Mantle, Lithosphere, Crust
List ALL the layers of the Earth IN ORDER including both crusts
continental crust, oceanic crust, lithosphere, asthenosphere, lower mantle, outer core, inner core
How many minutes does it take sunlight to reach the Earth?
About 8 minutes
Why does hot air or water rise? Talk about the molecules.
The molecules spread out and become less dense and rise when heated.
As the magma in the Asthenosphere heats up what is formed.
Convection Currents
Every _______ mile you decent beneath the crust, the temperature increases by ________ degree farenheit.
1/4 mile
34 degrees farenheit
Name two other metals that make up the core.
oxygen, sulfur, silicon
How many germs can a single sneeze blast out?
around 100,000 germs and travel at speeds up to 100 miles per hour.
What is the relationship between temperature & density?
If there is high temperature, there is low density. If there is low temperature, there is high density.
Where does the heat come from that makes convection currents form in the Asthenosphere?
The inner core and outer core heats the magma in the asthenosphere which causes convection currents to form.
