Earth's Layers
What is the outermost layer of the Earth?
The Crust
Draw a model of a Transform Plate Boundary.
(Transform Plate Boundaries slide past each other)
What does Pangaea mean?
"All the Earth"
Fossils
Remains of natural life that has been preserved
What type of plate boundary is the San Andreas Fault in California?
Transform Plate Boundary
Iron
Draw a model of a Convergent Plate Boundary (oceanic or continental).
(Convergent Plate Boundaries collide)
What is continental drift?
The idea that Earth's continents once joined together as a single landmass that broke apart.
Asthenosphere
The upper part of the mantle
What type of scientist was Alfred Wegener?
Meteorologist (weather and climate)
What layer of Earth is responsible for the Earth's magnetic field?
Outer Core
Draw a model of a Divergent Plate Boundary (oceanic or continental).
(Divergent Plate Boundaries separate)
Why was Wegener's theory about continental drift rejected by the scientific community?
Wegener could not explain what causes the continents to move.
Subduction
When one plate sinks beneath another
In the Edible Lab, the nougat of the Milky Way represented what part of the Earth?
asthenosphere / mantle
Explain why this statement is true: The greater the depth one goes into the Earth, the warmer the temperature.
The closer you are to the inner core, the warmer it will be.
In what type of plate boundary does one plate subduct beneath another, causing the plate to melt and create volcanoes?
Oceanic-Oceanic or Oceanic-Continental Convergent Plate Boundaries
Explain how coal in Antarctica is evidence for continental drift.
Coal comes from tropical plants. If there is coal in Antarctica, then Antarctica must have once been in a tropical climate.
Convection Current
The transfer of heat and energy by the process of heat rising and cool taking its place
What type of plate boundary is located between South America and Africa? What is the official name of this boundary?
Oceanic-Oceanic Divergent Plate Boundary = Mid-Atlantic Ridge
Explain how the inner core is responsible for movement on the crust.
The inner core is as hot as the sun. This heat creates convection currents in the mantle, which causes the crust to move.
What two plate boundaries produces no volcanoes?
Transform Plate Boundaries & Continental-Continental Convergent Plate Boundaries
Explain how glacial deposits (glacier scratches) in India and Africa are evidence for continental drift.
India and Africa are warm places and are not anywhere near glaciers. For there to be glacial deposits in Africa and India means they must have once been cold climates.
Density (I will accept an image/model)
the quality of having particles that are tightly packed together
If the inner core cooled, what would happen to the outer core, the mantle, and the crust?
The outer core would become a solid, there would no longer be convection currents in the mantle, and thus there would no longer be continental drift on the crust (no more earthquakes or volcanoes).
