Sedimentary rocks
Small solid pieces of material that come from rocks or living things
Sediment
Igneous rocks are classified by their ____________, Texture, and Mineral composition
Origin
Metamorphic rocks whose grains are arranged randomly
Nonfoliated rocks
Erosion
the process by which running water, wind, or ice carry away bits of broken-up rock
A sedimentary rock that forms where the remains of plants and animals are deposited in layers
Organic rock
Igneous rock that forms when magma hardens beneath Earth's surface.
Intrusive rock
Foliated Rocks
Metamorphic rocks that have their grains arranged in either parallel layers or bands
Weathering
the effects of freezing and thawing, plant roots, acid, and other forces on rock.
a sedimentary rock formed when rock fragments are squeezed together.
Clastic Rocks
Extrusive rock
Igneous rock that forms from lava on Earth's surface
Geologists classify metamorphic rocks according to the arrangement of the _______________ making up the rocks.
Grains
Most sedimentary rocks are formed through a sequence of processes: in order
weathering, erosion, deposition, compaction and cementation
Rock that forms when minerals dissolved in a water solution crystallize
A chemical Rock
as the rock in earths crust moves through the rock cycle material is not lost or gained.
Any rock that forms from another rock as a result of changes in ______________ or ________________ (or both) is a metamorphic rock
heat, pressure
the process that presses sediments together
Compaction
The three major groups of sedimentary rocks are
Clastic Rocks, Organic Rocks, and Chemical Rocks
Forces deep inside the earth and at the surface produce a slow cycle that _____________, _____________, and ________________ the rocks in the crust.
Builds, destroys and changes
Name two things people have used metamorphic rock for in the past and present
Sculpture, Buildings, weapons/tools
Cementation
the process where dissolved minerals crystallize and glue particles of sediment together
