Plate Tectonics
The theory that Earth's outer shell is divided into large, moving plates
What is Plate Tectonics
Rock formed when magma or lava cools and solidifies
What is Igneous Rock?
Molten rock that has erupted onto Earth’s surface.
What is lava?
The process that breaks down solid rock into smaller pieces through wind, rain, or chemical action.
What is Weathering?
The dark, organic material in soil created by decaying plant and animal matter.
What is Humus?
The type of boundary where two tectonic plates pull away from one another, creating a new crust.
Rock formed from layers of compacted particles and fossil remains
What is Sedimentary Rock?
Sedimentary Rock is made from these two processes.
What are Weathery and Erosion?
The process of moving broken rock and sediment from one place to another by wind, water, ice, or gravity.
What is Erosion?
Fossils are almost always found in this specific class of rock.
What is Sedimentary?
The process where a denser plate sinks beneath a lighter plate
What is subduction?
Rock transformed deep underground by extreme heat and pressure without melting.
What is Metamorphic Rock?
Any rock must undergo this process before it can turn into an igneous rock.
What is Melting?
The process where carried sediments settle down and drop in a new location.
What is Deposition?
Any rock must undergo this process before it can turn into an igneous rock.
The transform boundary line in California that is famous for causing frequent earthquakes
What is the San Andreas Fault?
Igneous rock that cools slowly beneath Earth’s surface, forming large crystals like granite.
What is Intrusive Igneous Rock?
Small pieces of rock, sand, minerals, and organic material created by weathering.
What are Sediments?
Plant roots growing into a crack in a boulder and splitting it apart over time is an example of this type of weathering.
What is Physical Weathering?
The two processes that press sediments together into solid sedimentary rock over time.
What is compaction & cementation?
The heat-driven movement within Earth's Mantle that causes tectonic plates to shift.
What are convection currents?
The distinct banded or layered appearance found in some metamorphic rocks like slate or gneiss.
What is Foliation?
True or False: Any rock type (Igneous, Sedimentary, or Metamorphic) can turn into any other rock type given the right path in the rock cycle.
What is True?
A landform created at the mouth of a river where sediment drops out as water slows down entering a sea or ocean.
What is a Delta?
The name of naturally occurring crystal substances. Rocks are generally made of one or more of these.
What are Minerals?
