What process is the pictures showing?
comprehension
mantle
Earth's layers
convection
melting
What processes causes tectonic plates move?
mountain building
earthquakes
convection currents
water cycle
subduction zones
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
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 exists that proves that Earth has layers?
They can be seen from special locations on the Earth
observations of earthquakes and buildings swaying
seismic data from earthquakes on the other side of the Earth
tsunami data from other countries and the impact on the land
rock samples from deep layers
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 Earth's inner core is solid but the layer around it, the outer core, is a liquid.
Turbulence or movement in that layer can allow the inner core to turn upside down. When this happens:
Earthquakes occur
The tides change
The tectonic plates converge
Magnetic North switches to south
Polar bears hibernate
Earth's layers are not all the same temperature or ________________. This is what causes them to form layers.
age
size
depth
radioactive decay levels
density
Radioactive isotopes decay in the Earth's core. What process does this decay cause?
Earth's rotation to slow down every couple of millions of years
Convection cells to have the heat needed from the core for convection movement
Day and night diurnal sequences
Solar eclipses
Whales to beach themselves every 10 years on the east coast above Florida
The heat from the interior of the Earth is very, very slowly being lost. Where is it losing this thermal energy?
Earth's surface
Earth's oceans
Earth's moon
Earth's poles
Earth's equator
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
Heat inside the Earth's core is maintained due to
Heat and pressure from gravitational pull
Decaying radioactive isotopes in the core
Core layers slowly changing over time
Liquid outer core turbulence
Daylight savings time changing once a year
