Earth's Layers
Metamorphic rock is formed thanks to these factors of force and energy.
What is heat and pressure?
the scientific theory that explains how the Earth’s surface is divided into large plates of rigid rocks that move with respect to each other; each plate moves over Earth’s hot mantle
What is the theory of plate tectonics?
vibrations in the ground that result from the movement along breaks in the Earth’s lithosphere; it occurs rapidly as a release of energy that produces waves of energy that radiate through the Earth in all directions
What are earthquakes?
These are the three types of plate boundaries.
What are convergent, divergent, and transform?
A scientific _______________ explains "why" something happens.
What is theory?
This process creates small pieces of rock that can later become sedimentary rock.
What is weathering?
this is the idea that the continents are in constant motion on Earth’s surface; they have slowly moved apart over time to their current positions
What is continental drift?
a vent in Earth’s crust through which molten rock flows; these can occur at divergent and convergent boundaries, when magma flows up to fill the space between the moving plates
What are volcanoes?
This boundary is capable of the strongest tsunamis and earthquakes, due to its higher potential for vertical land movement.
What is a convergent boundary?
Homer notices that his shower is covered in a strange green slime. His friend Barney tells him that coconut juice will get rid of the green slime. Homer decides to check this this out by spraying half of the shower with coconut juice. He sprays the other half of the shower with water. After 3 days of "treatment" there is no change in the appearance of the green slime on either side of the shower. What is the controlled variable/control?
"He sprays the other half of the shower with water."
This is the "dropping" of sediment that can become sedimentary rock.
What is deposition?
This causes the movement of plates.
What is convection?
a type of volcano that forms from a column of mantle away from a plate boundary in an area that is hotter than the surrounding material, so it is less dense and rises to the surface and forms a volcano
What is a hot spot?
the action that occurs at a convergent boundary where the denser plate sinks below the less dense plate.
What is subduction?
This is the solid layer that is somewhat flexible in the upper mantle that is located just below the lithosphere; lithospheric plates "float" and move on this layer.
What is the asthenosphere?
This is the scientific law that states that in undisturbed rock layers, the oldest rocks are at the bottom.
What is the law of superposition?
the shape of the ocean floor that resembles land and is influenced by plate tectonics
What is an ocean basin?
These are the divergent boundaries that occur "above ground", rather than beneath the ocean.
What are rift valleys?
Bart hypothesizes that root beer will produce taller hamsters if they drink it. In the experiment he’s planning, what would be the dependent variable?
What is height (taller hamsters)?
These are the various physical properties that distinguish the layers of earth.
Earth's layers are distinguished by physical properties like density, temperature, pressure, and state of matter (solid, liquid).
This plate boundary is most likely to form mountains.
What is Convergent?
the process by which new oceanic crust is formed along a mid-ocean ridge and older oceanic crust moves away from the ridge
What is seafloor spreading?
These are some known locations of each type of plate boundary (convergent, divergent, and transform).
