WHAT AM I?
These are inorganic solids with known chemical compositions and a crystalline structure.
What are minerals?
These physical properties are used to identify WHAT?
Cleavage, color, fracture, hardness, luster, streak, taste?! (What!! Ms. Byard didn't let us lick them?)
Minerals
Three types of rocks?
Sediment
Igneous
Metamorphic
What breaks up rocks during the sedimentary process?
Weathering.
A mixture of rock fragments, decaying organic matter, water and air...
WHAT IS SOIL?!
A tool used to determine the hardness of minerals.
What is the Mohs Hardness Scale?
The minerals and the grains in the rock sample tell us what?
It's composition.
Rocks move onto the Earth's surface.
What is uplift?
How sedimentary rocks are formed.
Sediment is piled and collected over time, then compacted, then cemented together.
A process of changing living material into organic matter
Decomposition.
Breaking down..
I am the hardest mineral.
A Diamond.
BLING, BLING!!
The arrangement of atoms determines what?
The crystalline structure of a mineral.
The natural processes that change rocks.
Weathering and erosion.
How does weathering effect rocks?
Changes them due to wind, rain, chemicals can break them down too.
Remains of something once alive
Organic material
I can tell what time period the surrounding rock is from. I am pretty important and really hard to find.
Index fossil.
These protect our coastlines and absorb storms before they get to the mainland.
Wetlands
What happens UNDER the ground during the rock cycle?
Heat and pressure change rocks into metamorphic rocks
or
rocks melt and are made into igneous rocks again when they cool off.
2 examples of weathering
ice wedging, sea arch erosion, plant's roots, animals, wind...
Remains of something that has never been alive
Inorganic material
I am the fragments that make up rocks. I am used to classify rocks along with shape and chemical composition.
I am a grain.
What are some uses of minerals?
Construction, materials, fertilizers, gemstones, jewelry.
Explain the rock cycle!!
Series of processes that change one type of rock into another.
Sediment is moved under the Earth's surface and above the Earth's surface with added heat and compression to form rocks which are changed by weather and erosion and changes in temperature and pressure.
How can weathering change the surface of the Earth?
Freezing and rain can erode the earth and change the shape of the surface.
Soil is broken down into layers... What are they called?
