Which 3 things increase as depth increases into the Earth?
time
Pressure
temperature
density
What is the thinnest layer of the Earth?
Mantle
inner core
outer core
crust
Why is the core more dense than the mantle or crust?
It has more aluminum
it has more iron
it has more tin
it has more basalt
How do scientists know the Earth has layers?
Drilling into the mantle
Volcanoes
Seismic waves data
ocean waves
What process is the pictures showing?

subduction zones
What kind of energy moves the molten rock in Earth's mantle?
thermal energy
chemical energy
personal energy
solar energy
wind energy
What phenomena takes place that results in the formation of new crust at mid-ocean ridges?
Earthquakes
Inner Core turbulence
plate tectonics
erosion of mountain ridges
magma rising to the surface
What evidence is there of Earth's magnetic field changing directions?
Earth moving through seasons
Minerals aligned to magnetic north in hardened crust
Crust hardening at mid-ocean ridge
magma erupting through mid-ocean ridge
Earth's rotation around the Sun
The speed of a seismic wave (from earthquakes) depends on the material it is traveling through.
This has helped us learn about:
Earth's layers
Rotation of the planet
Rock cycle
Fault lines
Subduction zones
The theory of plate tectonics is supported by the fact that
The oldest rocks are on the bottom of layers of rock
Glaciers move very slowly
Ocean currents have changed over time
Weathering and erosion are very common
Magnetic reversals can be seen in the rock of the ocean floor
