Vocab 1
This sphere is made up of all the rocks and minerals on Earth.
What is the geosphere?
This is the name for the small solid pieces of material from weathered rocks and organic material that is deposited by erosion.
What is sediment?
This type of rock is formed when layers of broken rocks and organic material are put under pressure and are cemented together.
What are sedimentary rocks?
These are 4 things that can cause weathering.
What are wind, water, ice and chemicals?
(also could be sand)
Fossils will be found in this type of rock.
What is sedimentary rock?
This is the word for the the molten mixture of rock forming substances, gasses and water from the mantle.
What is magma?
This is the one difference between magma and lava.
What is the location?
magma-mantle
lava- surface
This type of igneous rock is formed underground.
What is intrusive igneous rock?
Through this process, heat and pressure cause a rock's atoms and crystals to rearrange.
What is crystallization?
This is the most common type of crystal on Earth.
What is quartz?
This is the process in which weathered sediments are laid down in a new location.
What is deposition?
This is the process that carries weathered pieces of rock away.
What is erosion/transport?
The rock cycle takes place in these two layers of the geosphere.
What are the crust and the mantle?
Crystallization leads to the formation of this type of rock.
What is Igneous rock?
The youngest fossils will be found in this layer of rock.
What is the top layer?
The process in which rocks are pushed to the surface of the Earth's crust.
What is uplift?
Moving water can cause these two steps of the rock cycle.
What are weathering and erosion?
Obsidian is an example of this type of igneous rock
What is extrusive igneous rock?
These two C's allow sediment to stick together and turn solid i order to form sedimentary rocks.
What are compaction and cementation?
Most rocks on Earth are this type of rock.
What are sedimentary rocks?
This is caused by heat and pressure around a rock and leads to crystallization.
What is melting?
These are two minerals that can stick sediment together during cementation.
What are silica and calcite?
This type of rock is formed by heat (that is not hot enough to melt the rock) and high pressure.
What is metamorphic rock?
These two processes turn sedimentary rocks into metamorphic rocks.
What are deformation and metamorphism?
The state rock of NH is granite and is an example of this type of rock.
What is a igneous rock?
