What types of samples do Geologists use to study the Earth’s interior?
What is Rock and Soil
100
List three examples of radiation.
What is Sunlight, heat from a flame, heat from the electric heater.
100
What is Pangaea?
What is the supercontinent that Wegner believed was once made up of all continents.
100
What is a trace of an ancient organism that has been preserved in rock?
What is fossil
100
What are seismic waves? What causes them?
What is Vibrations that travel through Earth, carrying energy released during an earthquake.
200
What are the three main layers of the Earth?
What is Crust, Mantle, Core.
200
Define conduction.
What is the transfer of heat within or between materials.
200
Explain why Wegner’s hypothesis of continental drift was rejected.
What is he did not have satisfactory evidence proving the force that pushes or pulls the continents.
200
What is a plate?
What is a section of the lithosphere that slowly moves over the asthenosphere, carrying pieces of crust.
200
How does convection occur in the mantle?
What is The cooler, denser mantle rock sinks, as the hotter less dense mantle rises. As this hot mantle rises, it cools and sinks, creating a convection current.
300
Where is crust the thickest?
What is Under mountains
300
The movement of heat in soup while it is cooking is an example of which type of heat transfer?
What is Convection
300
What does the theory of plate tectonics explain?
What is the formation, movement, and subduction of Earth’s plates
300
The result from a force pressing on an area.
What is pressure.
300
Explain why the temperature of the Earth increases the deeper you go.
What is The temperature of the Earth increases the deeper you go into the Earth due to the intense pressure.
400
What are the three main layers of the mantle?
What is Lithosphere, Asthenosphere, Lower mantle
400
What is the theory of continental drift?
What is the idea that continents slowly move over Earth’s surface.
400
List the evidence that supports sea-floor spreading.
What is Eruptions of molten material, magnetic stripes in the rock of the ocean floor, and the ages of the rock.
400
Define subduction.
What is the process by which ocean floor sinks beneath a deep-ocean trench and back into the mantle.
400
The mantle of the Earth is 1800 miles thick. The lower mantle is 1400 miles thick. How thick is the upper mantle?
What is 400 miles thick.
500
This layer of the mantle is the softest and can be compared to softened road tar.
What is the asthenosphere
500
What did Alfred Wegner study to support his theory of continental drift?
What is Land features, fossils, and climate change
500
What is a mid-ocean ridge?
What is An underwater mountain chain where new oceanic crust is formed.
500
What are convergent, transform, and divergent boundaries?
What is Divergent boundaries are boundaries that occur when two plates move apart from one another along the mid-ocean ridge.
Convergent boundaries are boundaries that occur when two plates collide.
Transform boundaries are boundaries that occur when two plates slide past each other.
