IGNIS
Sediment is moved by...
What is forces of erosion (wind, gravity, ice and water)?
Where are metamorphic rocks formed
Deep in the earth's crust
The three categories all rocks can be put into
What is Sedimentary, Igneous & Metamorphic?
Igneous rock is formed by.
What is molten magma or lava cools and becomes hard?
Particles of rock, sand, soil, pebbles, and once living things.
What is sediment or clasts?
A rock that was sediment, then went under pressure, then was melted down and crystalized or cooled inside a volcano is this type of rock.
What is (an intrusive) Igneous rock?
Give one defining characteristic for obsidian
What is black volcanic glass?
2 main methods of which sedimentary rock forms
What are compaction and cementation ?
This is how metamorphic rock differs from igneous.
What is metamorphic rocks do not crystallize from magma/lava but they have stripes and crystals from heat and pressure.
These types of rocks can become sediment by weathering
What is any rock type? sedimentary, igneous & metamorphic
These are the two types of igneous rocks.
*BONUS points IF you explain how each type forms
What is intrusive (below Earth's surface) and extrusive (above or at Earth's surface)?
What movement of tectonic plates would create metamorphic rocks?
subduction or convergent
This is how a rock is different from a mineral.
What is a mineral is an inorganic substance that occurs naturally and a rock is made up of minerals and sometimes organic matter?
Metamorphic rocks form in water and usually have layers.
What is False
Igneous rocks are formed by
A. Magma
B. Lava
C. Hot magnetic formations
D. Both magma and lava
D.
Explain Lithification
What types of rocks change into metamorphic rocks?
What is any other type of rock (igneous, sedimentary, & metamorphic)?
This is the process of how an igneous rock becomes a sedimentary rock.
What is the igenous rock weathers down into sediment, the sediment then settles, compacts & cement into a sedimentary rock?
