Igneous
These are the three types of sedimentary rocks.
What are clastic, chemical and biochemical?
**Bonus- what is the difference between chemical and biochemical?
This is the difference between foliated and nonfoliated rocks.
What is foliated rocks have layers and nonfoliated rocks are more uniform in color?
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?
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)?
This is how metamorphic rock differs from igneous.
What is metamorphic rocks do not crystallize from magma/lava?
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
TRUE or FALSE: If a rock is light-colored then the rock is likely LOW in silica
What is flase? Light-colored = HIGH silica
Sediment is moved by...
What is forces of erosion (wind, gravity, ice and water)?
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?
