What is crust?
The type of rock where fossils are found.
What is sedimentary rock?
The rim of the Pacific plate, where 75% of Earth's earthquakes are found.
What is the Ring of Fire?
An earthquake underwater can produce a giant wave, called this.
What is a tsunami?
These plate boundaries involve two plates moving AWAY from each other.
What are DIVERGENT boundaries?
The type of fossil that preserves an impression of the outside of an organism's body.
What is a mold fossil?
The term for molten rock that is found inside the Earth.
What is magma?
The largest earthquakes tend to happen along these plate boundaries, where two plates collide with each other.
What are convergent boundaries?
These plate boundaries involve plates moving TOWARD each other.
What are CONVERGENT boundaries?
The type of fossil that creates a replica of the original organism or body part.
What is a cast fossil?
A broad, flat volcano that is formed by gentle flows of lava.
What is a shield volcano?
The type of fault that forms along a transform plate boundary.
What is a strike-slip fault?
These plate boundaries involve plates moving PAST each other.
What are TRANSFORM boundaries?
Two of the three substances that can preserve a whole organism.
What are tar, amber (tree sap), and ice?
A small, short-lived volcano that spews thin lava straight into the air, which falls back down as cinders.
What is a cinder cone volcano?
Of the three waves produced by an earthquake, these waves tend to cause the most damage to surface structures?
What are surface waves?
Convection currents in this upper, plastic-like layer of the mantle cause tectonic plates to move.
What is the asthenosphere?
The process where organic matter is replaced by minerals, creating fossils made of rock.
What is petrification?
A volcano that erupts violently and produces both lava flows and ash clouds.
What is a composite volcano?
Of the waves produced by an earthquake, these are the fastest, and can move through both solids and liquids.
