A mineral's streak is the _______ of the powder that appears when you scrape it on a surface color
How do you perform a streak test? the streak test is done by scraping a specimen of the mineral across a piece of unglazed porcelain known as a "streak plate." This can produce a small amount of powdered mineral on the surface of the plate.
Luster is the ________reflects off a mineral's surface way the light
Clam fossils have been found in many mountain ranges all over the world. Which of the following BEST explains how fossilized clams could have been embedded in the rock of mountain ranges? Fossils formed in sedimentary rock layers, which were uplifted to become mountains
Compaction occurs when deeply buried rock pieces are forced together by pressure. Compaction is involved in which of the following geological processes? Sedimentary rock formation
Geologists are conducting a study on many layers of different types of rock in the Grand Canyon. These geologists will likely find ancient fossils that reveal the history of life near the Grand Canyon in. Layers of sedimentary rock
Transportation of sediments to new sites is a major step in sedimentary rock formation. One of the major methods of sediment transportation is __________. Glacier movement

How do we identify Minerals? 1) Streak Color 2) Luster 3) Hardness 4) Breakage patterns
What is a fracture break? Fracture is the tendency of a mineral to break along curved surfaces without a definite shape.
Fossilization is the process of… Water filled with minerals seeps into the bone and replaces the chemicals in the bone with other minerals that are as hard as a rock.
The process that takes place when the soft tissues of animals’ skin and organs are preserved for thousands of years is called… Mummification
What is a fossil? A fossil is the presrved remains of a once living organism.
