2.1 Minerals
True or False: A mineral must be a solid.
True
Rocks can form when pieces cement together. Does cement mean to glue or to press?
cement = to glue
Which type of rock forms from intense heat and pressure? igneous, sedimentary, or metamorphic
metamorphic
What tool do you use to measure mass? (graduated cylinder or a balance scale)
Balance Scale
True or False: Minerals are man-made, not natural
False
Compaction happens when pieces of rocks are (glued or pressed) together
Pressed together.
Which type of rock forms from the compacting and cementing of sediments? igneous, sedimentary, or metamorphic
Sedimentary
What tool can you use to measure volume? a balance scale, a graduated cylinder, or a ruler
a graduated cylinder (for oddly shapes objects)
a ruler for box-shaped objects
Luster is the way a mineral _______ light. (reflects or rejects)
reflects
In the rock cycle when magma cools, what type of rock is formed? Igneous or sedimentary
Igneous
Fossils can be found in which type of rock - igneous, sedimentary, or metamorphic?
sedimentary
Density is equal to an object's mass divided by its volume. If an object has a mass of 12 grams and a volume of 4 milliliters, is its density 3 g/ml or 48 g/ml?
3 g/ml
The Mohs scale is used to rate the hardness of minerals. A diamond is one of the hardest minerals. Is it rated a 10 or a 2 on the Mohs scale?
A diamond is rated 10 on the Mohs scale
In the rock cycle heat and pressure creates what type of rock? metamorphic or igneous
metamorphic
Which type of igneous rock forms when magma cools slowly and large crystals form? (intrusive igneous or extrusive igneous)
Intrusive igneous
Name a word that starts with a "W" that causes rocks to change type.
Weathering
Density is equal to an object's mass divided by its volume. If an object has a mass of 10 grams and a volume of 5 milliliters, is its density 2 g/ml or 50 g/ml?
2 g/ml (10 divided by 5 = 2)
Name a word that starts with an"E" that causes rocks to change type.
Erosion
Which type of igneous rock forms when lava cools quickly and small or no crystals form? (intrusive igneous or extrusive igneous)
extrusive igneous
Name a rock (e.g. granite) that starts with an "S" or "M"
Sandstone, Slate, Shale
Marble
