Igneous, Sedimentary, or Metamorphic
Visible Layers
What are Stratifications?
Made of one or more naturally occurring, non-living, pure substances
What are Rocks
a mineral’s shininess, can be described as “metallic lustre” (shiny) or “non-metallic lustre” (dull)
What is lustre?
Lava is an example of this
What is extrusive?
The process of rocks breaking down into sediment.
What is Weathering?
These rocks are formed from lava
What is Igneous?
Pure substances (can be elements or compounds)
What are Elements
The colour left behind when a mineral is rubbed across a piece of unglazed porcelain tile
What is a Streak?
Magma is an example of this
What is intrusive?
This is made up of:
-small pieces of sediment
-organic matter such as leaves, twigs, dead worms and insects
-small spaces which contain air or water
What is Soil?
These rocks contain fossils
What are Sedimentary Rocks?
The scale to tell how hard a mineral is
What is the Moh's Scale?
Breaking apart into smooth, flat surfaces
What is Cleavage?
This turns Igneous and Sedimentary rocks into Metamorphic rocks
What is heat and pressure?
The movement of rocks and mineral grains from one place to another.
What is Erosion?
A igneous or sedimentary rock that has changed form due to high heat and pressure.
What is Metamorphic?
The softest mineral in the world
What is Talc?
Breaking apart into rough or jagged edges
What is Fracture?
The OG rock
What is parent rock?
Break-up of rocks caused by living organisms; animals, plants, bacteria, fungi
What is Biological Weathering?
Shale turns into this after Heat and Pressure
What is Slate?
The different ways we can identify minerals
What are:
Are solids
Are naturally occurring (not man-made)
Are inorganic (not living or not made from living things)
Have a fixed chemical composition
Have a crystal structure
the outermost shell of a terrestrial planet.
What is a Crust?
This turns Metamorphic rocks in Sedimentary rocks
What is weathering and erosion?
These can all cause changes in the surface of the Earth.
What is Gravity, wind, and water?
