Classify That!
The three types of rocks.
What are igneous, sedimentary, and metamorphic rocks?
This rock contains sediment.
What is a sedimentary rock?
This is formed when molten, liquid rock cools down to become solid rock.
What is igneous rock?
This is a geological concept detailing the transitions through time of the three rock types (i.e. the relationships between the rock types).
What is the rock cycle?
Rocks are classified by their ___________ .
What is formation?
This rock has a close relationship with magma.
What is a intrusive metamorphic rock?
This is formed when biological material gets compressed over millennia and becomes rock.
What is biologic/organic sedimentary rock?
The formation of a rock tells us about this important subject - so we can learn from the past.
What is Earth's history?
Two types of sedimentary rock.
What are clastic and biologic (organic)?
This rock pressures other rocks into submission to be "one of them".
What is a metamorphic rock?
This is formed when minerals in rocks are compressed so hard they become flat, elongated, and visibly aligned.
What is foliated metamorphic rock?
This rock requires both heat and pressure to form.
What is metamorphic rock?
Two types of igneous rock.
What are intrusive and extrusive?
Limestone is a rarity because it falls into these two categories.
What are clastic and biologic sedimentary rocks?
This is formed by slow-cooling magma, which creates large mineral crystals within the rock.
What is intrusive igneous rock?
This rock cycles from liquid (not a rock) into solid through the melting and cooling process.
What is igneous rock?
Two types of metamorphic rock.
What are foliated and non-foliated?
These rocks are almost exclusively found near and around volcanoes.
What is an extrusive igneous rock?
This type (category and sub-category) of rock has one of the highest occurrence of fossils.
What is biologic sedimentary rock.
This rock is formed from former rocks that have been weathered and lithified, and then compressed and compacted into this rock.
