100
A light colored, high silica, volcanic rock that can erupt explosively.
What is a Rhyolite.
100
Rocks are made of these:
What is Minerals.
100
Rocks formed by high heat, pressure and chemically active fluids.
What is metamorphic rocks.
100
The most common rock forming mineral
What is quartz
100
The type of rock that usually has fossils.
What is Sedimentary.
200
A dark colored, high Fe and Mg, volcanic rock - the type that is found in Hawaii
What is a Basalt.
200
This is how rocks are classified:
What is how they were formed (their origin).
200
This metamorphic rock shows bands of different minerals.
What is gneiss.
200
Forms rectangular shaped, twinned, crystals and is common in volcanic rocks.
What is feldspar
200
When a plant or animal leaves marks in the earth that are preserved.
What is Trace Fossil.
300
A very course grained rock that cooled slowly from magma.
What is an Intrusive Rock.
300
These are rocks formed from the solidification of magma.
What is Igneous Rocks.
300
This metamorphic rock will fizz under a dilute acid.
What is Marble.
300
Commonly known as "fools gold"
What is pyrite
300
Creepy crawly bug from 500 million years ago (arthropod).
What is a Trilobite
400
This rock cooled so fast it turned to glass.
What is a Obsidian.
400
These rocks are formed through compaction and cementation.
What is Sedimentary Rocks.
400
Exposing sandstone to extreme heat and pressure without melting will make this rock.
What is Quartzite.
400
The most common mineral in Indiana
What is calcite
400
Marine animals that have hard "valves" (shells) on the upper and lower surfaces.
What is a Brachiopod
500
This rock cooled deep within the earth and contains plagioclase feldspar and pyroxene.
What is a Gabbro.
500
Metamorphic rocks can be naturally made from these types of rock.
What is Igneous, Metamorphic and/or Sedimentary.
500
This forms the layers or banding in a metamorphic rock.
What is Pressure.
500
A mafic mineral, often bright green, with poor cleavage, found in volcanic rocks. Usually the first mineral to form in a magma.
What is Olivine
500
A geologic period and system of the Paleozoic Era, spanning 60 million years from the end of the Silurian Period, about 419.2 million years ago.
What is Devonian.
