100
naturally occuring, inorganic solid with a definite structure and composition
What is mineral
200

What is mass and size
200
What does the word metamorphic mean?
What is change of form
200
A solid with a repeating pattern of atoms is a what
What is crystal
300
How many minerals have been identified and where can we find them?
What is over 4,000 and glass, bricks, pencils, beakers, door knobs, chairs, lockers, computers, rings, etc.
300
remains or traces of once-living plants or animals is called what
What is fossil
300
How do scientists determine if rocks are igneous, sedimentary, or metamorphic?
What is by how they were formed
300
2 main types of metamorphic rocks are? (not names of rocks)
What is foliated and nonfoliated
300
Minerals can be identified by this (powdered form) and have levels of hardness that vary on what scale? (name the powdered form of the mineral, the name of the scale, and the ten levels of the scale)
What is streak, Mohs hardness scale, and 1-talc, 2-gypsum, 3-calcite, 4-flourite, 5-apatite, 6-feldspar, 7-quartz, 8-topaz, 9-corundum, 10-diamond
400
What is the difference between cleavage and fracture?
What is minerals that split into pieces with smooth regular sheet have cleavage; minerals that break into chunks with jagged, rough edges have fracture
400
3 main types of sedimentary rocks are? (not names of rocks)
What is detrital, chemical, organic
400
Igneous rocks formed when magma cools below the crust are called what? Igneous rocks formed when magma cools ON the crust is called what?
What is intrusive and extrusive
400
How do metamorphic rocks form from older rocks? What must happen to the rocks to make them metamorphic?
What is the must heated and/or squeezed
400
Draw the rock cycle diagram (include the 3 main types of rocks, sediment, and magma).
What is sediment goes to sedimentary rocks to metamorphic rocks, to magma to igneous rocks to sediment.
500
What is luster?
What is describes how light reflects from a minerals' surface.
500
sedimentary rocks are produced when these things collect to form rock layers (not sediment)
What is pieces of other rocks, plant and animal matter, or dissolved minerals
500
What is the difference between basaltic and granitic rocks?
What is basaltic rocks are dark-colored, extrusive, and contain iron, magnesium, or calcium ; granitic rocks are light-colored, intrusive and contain silica
500
How could a metamorphic rock turn into a sedimentary rock and back to metamorphic?
What is the metamorphic rock could weather and break apart, then the pieces of sediment could be blown away and deposited until they are put under pressure into a sedimentary rock, then the sedimentary rock could be put under heat and compaction and turn into a metamorphic rock
500
What is the difference between a rock and a mineral?
What is a mineral is naturally occuring, inorganic solid with same general chemical makeup; rocks are solids usually made of 2 or more minerals
