Earthy Mysteries
100

The theory that Earth's outer shell is divided into large, moving plates

What is Plate Tectonics 

100

Rock formed when magma or lava cools and solidifies

What is Igneous Rock? 

100

Molten rock that has erupted onto Earth’s surface.

What is lava? 

100

The process that breaks down solid rock into smaller pieces through wind, rain, or chemical action.

What is Weathering?

100

The dark, organic material in soil created by decaying plant and animal matter.

What is Humus? 

200

The type of boundary where two tectonic plates pull away from one another, creating a new crust. 

What is Divergent Boundary 
200

Rock formed from layers of compacted particles and fossil remains

What is Sedimentary Rock? 

200

Sedimentary Rock is made from these two processes. 

What are Weathery and Erosion?

200

The process of moving broken rock and sediment from one place to another by wind, water, ice, or gravity.

What is Erosion?

200

Fossils are almost always found in this specific class of rock.

What is Sedimentary?

300

The process where a denser plate sinks beneath a lighter plate

What is subduction? 

300

Rock transformed deep underground by extreme heat and pressure without melting.

What is Metamorphic Rock?

300

Any rock must undergo this process before it can turn into an igneous rock.

What is Melting?

300

The process where carried sediments settle down and drop in a new location.

What is Deposition?

300

Any rock must undergo this process before it can turn into an igneous rock.

What is Melting?
400

The transform boundary line in California that is famous for causing frequent earthquakes

What is the San Andreas Fault? 

400

Igneous rock that cools slowly beneath Earth’s surface, forming large crystals like granite.

What is Intrusive Igneous Rock?

400

Small pieces of rock, sand, minerals, and organic material created by weathering.

What are Sediments?

400

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?

400

The two processes that press sediments together into solid sedimentary rock over time.

What is compaction & cementation? 

500

The heat-driven movement within Earth's Mantle that causes tectonic plates to shift. 

What are convection currents? 

500

The distinct banded or layered appearance found in some metamorphic rocks like slate or gneiss.

What is Foliation? 

500

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?

500

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?

500

The name of naturally occurring crystal substances. Rocks are generally made of one or more of these. 

What are Minerals?
