Rock Cycle
The two processes involved in forming Metamorphic Rocks
What are HEAT and PRESSURE?
Intrusive Rocks form here
Where is inside the Earth?
pieces of rock that range in size from clays to boulders
What are sediments?
When rocks are changed through contact with lava or magma
What is Contact Metamorphism?
What is pumice?
Sediments must undergo these two processes before they are compacted and cemented together to form Sedimentary Rocks.
What is DEPOSITION and BURIAL?
Extrusive rocks have crystals that are this size.
What is very small or none?
The two processes that form sediments
Hint- use your ESRT Rock Cycle diagram
What are weathering and erosion?
When rocks are changed through a large amount of pressure
What is Regional Metamorphism?
This igneous rock is a "rule breaker" - even though it appears dark in color, it is lower in density and felsic.
What is Obsidian?
These rocks form when molten rock COOLS and SOLIDIFIES.
What are Igneous rocks?
What is it took a long time?
These two processes form clastic rocks
What are compaction and cementation?
What is foliation?
This rock is made of metamorphosed Limestone or Dolostone
The term for gas pockets in some extrusive rocks
What is vesicular or vesicles?
Bioclastic rocks are made from this.
What are once living things, like shells, skeletons, plant remains.
This metamorphic rock has undergone such extreme pressure that the minerals are lined up in bands or stripes
What is GNEISS?
The types of rocks that the sediment in sedimentary rocks can be made of
What are ALL TYPES, Igneous, Sedimentary, or Metamorphic
The term that describes dark, dense rocks that are high in Iron and Magnesium
What is Mafic?
Rock salt or halite is an example of this type of sedimentary rock
What is Crystalline?
This clastic sedimentary rock is made of different sized sediments from cobbles to clays with sharp edges
What is Breccia?
