The Rock Cycle
How many types of rock are there? (number)
3
What law states that oldest rocks and fossils are lower in Earth's layers?
The Law of Superposition
What is the name of the new unit that we learned that explains how things sink or float?
Density
What specifically do we call Wegner's Theory?
Continental Drift
What 4 geologic hazards did we research in class?
Floods, Landslides, Earthquakes, Tsunamis.
Rock formed through the compressing and cementing of smaller pieces of rock.
Sedimentary Rock
How long does the rock cycle take?
Millions of Years
What is the equation for Density?
Density= Mass/Volume
What is the name of the supercontinent that Wegner taught us?
Pangea
What causes geologic hazards?
Tectonic Plate Movement
Rock formed from the cooling and crystallization of magma.
Igneous Rock
Name the two types of tectonic plates and name which is most dense.
Continental and Oceanic
Oceanic is most dense.
Which layers are solid?
Crust, Mantle, Inner Core
Define a convergent boundary and list what you would expect to find there.
A place where two tectonic plates move toward each other.
Mountains, volcanoes, earthquakes.
True or False, geologic hazards are created in the center of tectonic plates.
False
Rock formed when intense heat and pressure changes one rock type into another.
Metamorphic Rock
At which type of plate boundaries does the Earth's crust grow the most?
Divergent Plate Boundaries
What state of matter is the inner core?
Liquid
Define divergent boundary and share what you expect to find there.
A place where plates move away.
Volcanoes
True of False: Tornadoes are a type of geologic hazard.
(Hint: they are made by the mixing of winds)
False
Sedimentary -
Igneous -
Metamorphic -
For mountains to form, what type of tectonic plates must be involved? What type of boundary is this?
Continental Plates, Convergent Boundary
Which layer is the most dense?
Inner Core
Define transform boundary and share what you would expect to find there.
A place where two tectonic plates slide passed each other.
Earthquakes.
Where do earthquakes and volcanoes appear?
At the edge of plate boundaries
