Define the rock cycle and its characteristics.
A chain of processes that produce and transform the rock types in the earth's crust.
What are the two main types of igneous rocks?
Intrusive and extrusive
How are metamorphic rocks formed?
They are form by high heat and high pressure.
The characteristics of sedimentary rocks are?
They have layers of bedding and can sometimes contain fossils from plants or animals from some time ago.
What rock forms compaction and cementation?
Sedimentary Rock
Where are igneous rocks usually found?
They are usually buried below surface, between ocean water, and near volcanoes.
What are the characteristics of metamorphic rocks?
The characteristics of Metamorphic rocks are often squished, smeared out, and folded
What are the three main types of sedimentary rocks?

What power Earth's rock cycle?
Earth's interal heat
What are the characteristics of igneous rocks?
Two of the most important are melting temperature and viscosity (resistance to flow).
Give three examples of foliated metamorphic rock.
Three examples are slate, schist, and gneiss.
examples of sedimentary rocks are?
There are a few examples of sedimentary rocks but only a few rocks that are common and mainly known which are sandstone, limestone, and shale.
What are metamorphic?
Formed when other rocks are affected by great temperatures and pressures.
How are igneous rocks used in everyday life?
They are used for construction and countertops.
Where are metamorphic rocks usually found?
sedimentary rocks are usually found in or at?
they are usually found in oceans, deserts, and sometimes even caves.
where can rocks usually be found?
In general, igneous rocks and metamorphic rocks form most abundantly at divergent and convergent plate boundaries.
