A __________ is a natural, solid mixture of minerals or grains.
Rock
The __________ is a series of processes that change one type of rock into another.
Is a thin, outher layer of Earth.
Crust
Earthquakes occur at this type of boundary.
transform boundaries
This type of fossil is formed when minerals and sediment replace the organism completely and it is turned to stone.
Petrified
As rocks are broken down into smaller pieces or eroded by water, __________ forms.
sediments
This type of rock forms by small rock fragments compacting and cementing together.
sedimentary
This layer is at the center of Earth and is mad up of solid iron and nickel.
Inner Core
The Himalayan Mountains range was formed by plates that move toward each other. These plates are known as ____________________.
Convergent Boundaries
When a fossil dissolves and leaves an empty space it creates a _____ which can be filled in with sediments to create a replica of the fossil called a ______.
Mold, Cast
A rock that forms as magma solidifies into a __________ rock.
igneous
You would find this type of rock near a volcano.
Igneous
This layer of Earth is made up of molten and solid rock.
Mantle
Volcanoes and Rifts occur at this type of boundary.
Divergent Boundaries
Preserved footprints, tracks, or burrows.
Trace Fossils
A rock that forms from smaller bits of broken-down rock is a __________ rock.
sedimentary
Gneiss is an example of this type of rock, and it forms when granite is exposed to heat and pressure.
Metamorphic
As you move closer to the center of the Earth these conditions increase.
Temperature and Pressure
Type of Convergent Boundaries where the Oceanic Crust sinks underneath the Continental Crust.
Subduction
When whole organisms become frozen, trapped in tar or amber it creates this type of fossil.
Preserved Fossil
__________ rock is formed when an existing rock is exposed to extreme heat or pressure.
Metamorphic
All rocks can be turned into sediment by this process.
weathering and erosion
Magma move in the mantle in circular motions. This motion is called _________________.
convection currents
Tectonic Plates rest on this layer of Earth. (specific)
Lithosphere
Which type of rock contains fossils?
Sedimentary
