Minerals: Building Blocks of Rocks
Fast and Slow Changes
Sedimentary Rocks: "Settled"
Igneous Rocks: "Fire"
Metamorphic Rocks: "Heat and Pressure"
100
The way the surface of a mineral reflects light.
What is luster.
100
The BREAKING and cracking of earth materials.
What is weathering?
100
Tiny broken bits of rock, plants, bones, shells, and other animal material.
What are sediments?
100
Melted rock below Earth's surface.
What is magma
100
Part of the Earth, where metamorphic rocks form.
What is deep in the mantle, or below the surface?
200
Hardness, luster, color, streak, and cleavage.
What are ways to identify minerals?
200
When deposits are TRANSPORTED and deposited from one place to another by moving water, waves, wind, ice, and glaciers.
What is erosion?
200
Formed by moving things (wind, rivers, & streams) that are picked up, dropped off, and built on top of one another/
What are layers.
200
This is when magma reaches the surface.
What is lava?
200
Two process that must over to form metamorphic rocks.
What is squeezed together and heated.
300
Have a definite crystal shape, never living, formed by nature, & not made in the laboratory?
What are characteristics of minerals?
300
When material is PLACED in a new place such as the bottom of the lake or the ocean.
What is deposition?
300
Remains of living things from long ago that may be found in sedimentary rocks.
What are fossils?
300
These rocks form take years to cool off underground and large course grains.
What is intrusive igneous rocks.
300
This metamorphic rock is used to make chalkboards.
What is slate?
400
It can be scratched by glass, but not by a steel file. *Use Moh's Hardness Scale to identify the mineral.
What is feldspar?
400
Landslides, earthquakes, volcanoes, and tsunamis are examples of these process.
What are rapid or fast changes?
400
When sediments "get stuck together" after they harden through a chemical process.
What is lithify or lithification?
400
Rocks that cool off above ground in hours or minutes and form small grain that are hard to see.
What is an extrusive igneous rock?
400
Part of the word metamorphic that means "changed".
What is morph?
500
The properties to identify this mineral include: has nonmetalic luster; color is dark brown, black or silver white; no streak.
What is mica?
500
TWO types of weathering that create slow changes in the earth. First is when oxygen, carbon dioxide, and water in the atmosphere cause rocks to break apart and divide. Second is when freezing and thawing of water, wind, and tree roots break apart over time.
What are chemical and physical weathering?
500
These are two examples of sedimentary rocks.
What are sandstone, coal, limestone, bricca, shale, or conglomerate.
500
These are examples of igneous rocks.
What are granite, pumice, obsidian, rhyolite, or basalt?
500
These are two examples of metamorphic rocks.
What are slate, marble, schist, gneiss, or quartzite?
