Earth's Layers and Plates
The innermost layer of the Earth
What is the Inner Core?
The name for molten rock found underground
What is Magma?
This natural disaster occurs when a rock breakage underground releases energy in the form of seismic waves.
What is an Earthquake?
This process breaks rocks down into sediment
What is Weathering?
This type of volcano is formed when thin lava spreads out along the ground after eruptions
What is a shield volcano?
Tectonic plates are parts of this layer
What is the Lithosphere?
The arrangement of atoms and molecules within a mineral
What is Crystalline Structure?
Usually caused by an underwater earthquake, this natural disaster is a massive wave.
What is a Tsunami?
When water containing dissolved minerals flows through compacted sediment, this process occurs.
What is Cementation?
This event is the boundary between the Paleozoic and Mesozoic Eras, and killed 95% of ocean dwelling lifeforms.
What is the Permian Extinction?
This layer sits between the outer core and the asthenosphere.
What is the mesosphere?
The group of processes that form and transform the rocks of Earth
What is the Rock Cycle?
Resulting in falling ash, toxic fumes, and possible additional effects, this natural disaster results from pressure building inside a volcano
What is an explosive eruption?
What is Clastic?
This is the point on the surface directly above an earthquake's focus
What is the Epicenter?
A process occurring at Convergent Boundaries which produces Magma by destroying oceanic crust.
What is Subduction?
The concentration of this mineral determines which family an igneous rock belongs to
What is feldspar?
What is the Richter Scale?
Weathering creates sediment, Erosion moves it, but this process occurs when the sediment reaches its final location
What is Deposition?
The San Andreas Fault is the most famous example of this phenomena that occurs at Transform Plate Boundaries
What is a Transform Fault?
A kind of mineral which supports Continental Drift Theory by the direction its magnetic pole points
What is Magnetite?
Sedimentary Rock which contains material which was previously alive
What is Organic Detrital Sedimentary Rock?
Caused by large scale explosive eruptions, this natural disaster buried the city of Pompeii in ash when it rushed down Mount Vesuvius after an eruption
What is a Pyroclastic Flow?
These two materials are the most common sediment found in Organic Detrital Sedimentary Rock
What are Lithified Coral Bodies and Seashells?
This weatherman/adventurer was the creator of Continental Drift Theory
Who is Alfred Wegener?
