Metamorphic Rocks
True or False Gneiss is a metamorphic rock?
True
When rain or wind breaks any rock into small pieces making sediment without moving it is called:
What is Weathering
What are sediments?
peices of soild material that have been broken down on Earth's surface by wind, water, ice, gravity, or chemical precipitation
Which is smaller sand or clay?
What is clay
How do igneous rocks form?
Igneous rocks form from the cooling and solidification of lava or magma
How are metamorphic rocks formed?
Rocks are changed as a result of exposure to intense heat and/or pressure
Rocks are classified by how they _________.
What is Form
Why does the sedimentary rock conglomerate have rounded rocks or pebbles.
It forms in an aquatic environment, usually a river or coastline, where strong currents help to form the rounded particles as well as the fine matrix particles.
What are three types of sedimentary rocks?
see chart answers may vary
conglomerate. shale
breccia. limestone
sandstone,
siltstone,
Rocks that cool slowly and have large crystals are called?
What are intrusive rocks
With heat and pressure slate becomes_______
What is phyllite
Why aren't rocks classified by color?
Color could be the same across many different types of rocks.
sediments are classified according to their _____
Size
Which of these is classified as an inorganic land-derived clastic sedimentary rock?
conglomerate
Explain the properties of extrusive rocks?
They cool quickly, no crystals, may contain air bubbles
Explain contact metamorphism
Existing rock coming into contact with really intense heat from lava or magma. Imagine there is an intrusion of magma and all of the existing rock are burned by the heat of the magma.
The way rocks can change into other rocks over and over again is called ______
What is the rock cycle.
What is the best known feature of sedimentary rocks?
fossils
How sedimentary rocks are formed (hint:4 boxes)
Erosion & transportation, deposition, comnpactation and cementation.
Type of igneous rock that forms when lava hardens on the earth's surface.
What is extrusive igneous rock?
Explain regional metamorphism
There is pressure along the plate boundary, fault or crack. These plates come together at a convergent plate boundary. So here we see immense heat and pressure which causes the rocks in the middle to metamorphasize.
All along plate boundary’s we can see metamorphic rock.
What makes up the rock cycle?
igneous, metamorphic and sedimentary
What are the four main agents of erosion?
wind, moving water, gravity, and glaciers
What are the three rock types in the sedimentary chart?
Clastic, Chemical, and Organic
What is the process of the rock cycle?
it starts with weathering and erosion, that makes sediment, which turns into sedimentary rocks, and over time becomes metamorphic rocks, then it produces magma, thast turns into igneous rocks, and then it starts all over
