TEK 6.10B; Classifing Rocks
A student is expected to classify rocks
as a Metamorphic, Igneous, or
sedimentary by the process of their
Formed from the mantle, when cooled then forms Igneous rock.
Formed from layers of the earth compacting and cousing heat and pressure.
Rocks formed when particles of rocks and other materials are pressed together.
Classifying Sedemintary rocks
When a student is making a model of
the primary way that sediment and
organic material form from sedimentary
rocks, they should include the process
Classifying Igneous rocks
Scientists can tell when Igneous rocks
form slowly because igneous rocks with
a coarse crystal size will be cooled slower
than rocks with a fine grain size.
Classifying Metamorphic rocks
metamorphic rocks are classified on the
basis of texture (grain size, shape,
orientation) and mineral composition.
How does a metamorphic rock turn into an ignious rock?
Metamorphic rocks turn into igneous
rocks when a metamorphic rock melts
into magma and then cools into a
