The Quake that Shakes
Kaboom!
Hard as a Rock
Boundaries Abound
Earth's Layers
100
This is what happens to the difference in time between P and S waves when the distance from the epicenter increases.
What is increase in time?
100
They are two ways volcanoes can form.
What are hot spots and subduction zones? (divergent boundaries also acceptable)
100
They are the three types of rocks.
What are igneous, sedimentary, and metamorphic?
100
They are the three types of plate boundaries.
What are convergent, divergent, and transform?
100
They are the four main layers from inside to outside.
What are inner core, outer core, mantle, and crust?
200
They are the three types of earthquake waves.
What are P (primary), S (secondary), and surface waves?
200
It is molten rock under Earth's surface.
What is magma?
200
They are the three types of sedimentary rock.
What are clastic, chemical, and organic?
200
This is the process that occurs when two oceanic plates diverge.
What is ocean floor spreading?
200
It is the only liquid layer.
What is the outer core?
300
This is the point directly above the focus of an earthquake.
What is the epicener?
300
They are the three stages of a volcanoe.
What is extinct, dormant, and active?
300
The type of igneous rock that is more likely to form crystals.
What is intrusive igneous rock?
300
These form when two continental plates converge and neither subducts.
What is mountains form?
300
This is the semiliquid layer near the upper portion of the mantle.
What is the asthenosphere?
400
It is a scale that rates an earthquake's magnitude based on the size of its seismic waves.
What is the Richter scale?
400
They are the three types of volcanoes.
What are shield, cinder cone, and composite (strato)?
400
It is they type of rock in which fossils can form.
What is sedimentary rock
400
When two continental plate boundaries diverge, they form this.
What is a rift valley?
400
This is made up of the very top part of the mantle and Earth's crust.
What is the lithosphere?
500
The point belos the surface where rocks break under stress and cause an earthquake.
What is a focus?
500
This forms when two ocean plates converge and the more dense plate subducts.
What is an island arc?
500
It is a layer of cooled and hardened lava between layers of sedimentary rock.
What is an extrusion?
500
It is the name of the boundary separating the North American Plate from the Eurasion Plate.
What is the mid-Atlantic Ridge?
500
This is the force that moves the lithospheric plates.
What are convection currents?
