Title: When identifying a mineral, this is the test that measures how easily a mineral can be scratched, measure on a scale from 1 to 10.
1When identifying a mineral, this is the test that
measures how easily a mineral can be scratched,
measure on a scale from 1 to 10.
2When identifying a mineral, this is the test that
measures how a mineral reflects light such as
metallic, pearl, or dull.
3When identifying a mineral, this is the test that
measures a minerals mass compared to the same
volume of water.
4When identifying a mineral, this is the test that
shows the color of a minerals powder.
5When identifying a mineral, this is test showing
how a mineral breaks
6What are the three basic types of rocks?
- Igneous, metamorphic and sedimentary
7What are the two types of igneous rocks?
8List characteristics of intrusive rocks.
- Made INSIDE the earth
- Made of magma
- Cool slowly
- Made of large crystals
Granite, Gabbro
Example
9List characteristics of extrusive rocks.
- Made on surface of Earth
- Made of lava
- Cools quickly
- Rocks have NO or very tiny crystals
Example
Pumice, basalt, obsidian, scoria
10Igneous rocks that are dark in color, made mostly
of iron and magnesium are called
11Igneous rocks that are mostly light colored,
containing lots of silica are
12What are the two types of metamorphic rocks?
Characteristics examples
Banded or striped -gneiss, slate
Not banded or striped, larger crystals
quartzite, marble
13What is necessary to make metamorphic rocks?
- Extreme heat, pressure or hot liquids.
14What is necessary to make sedimentary rocks?
- Weathering (breaking up of rocks)
- then, erosion followed with
- Compaction or cementation of sediment
15What are some examples of sedimentary rocks?
- Sandstone
- Shale
- Conglomerate
- Limestone
- Coal
16What model illustrates the process to create and
change rocks?
17- What is the most common rock seen (75 of them)?
- What is the breaking down of rock called?
- What is the carrying away of sediment by natural
forces?
- Sedimentary rocks
- Weathering (done by wind, water, ice and gravity)
- erosion
18What two steps should occur for any rock to turn
into sedimentary rock?
- Weathering (breaking down of old rock)
- Compaction or cementation (pressing or glue rock
fragment together)
19What type of sedimentary rock is made of pieces
or other rocks or shells?
- DETRITAL
- EXAMPLES?
- BRECCIA, SANDSTONE, SILTSTONE, SHALE
20Halite is a sedimentary rock formed from
- Dissolved minerals water evaporates leaving
behind the halite (rock salt) - How is this rock classified?
- A chemical sedimentary rock
21What type of rock or rocks are made from once
living organisms that are cemented or compacted
together?
- ORGANIC SEDIMENTARY
- EXAMPLES? (name 3)
- LIMESTONE (tiny seashells)
- COQUINA (bigger pieces of seashells,
- CHALK, (microscopic seashells)
- COAL (plants die and chemically change)
22List 2 comparisons for igneous rocks.
- Made from molten material
- Near a volcano
- Must cool to become a rock
23Give at least 2 comparisons for metamorphic rocks
- They are put under great pressure or heat
- They are very dense rocks
24Give at least 2 comparisons for sedimentary rocks
- All are made of bits of rock, plants, animals
- Undergo weathering erosion to break down
- Pieces undergo compaction and cementation to put
pieces together to make a rock
25List a foliate metamorphic rock
26List a nonfolliated metamorphic rock
27Name 3 igneous extrusive rocks
- Pumice
- Scoria
- Basalt
- Obsidian
- Geode
28Name 2 intrusive igneous rocks
29What 2 processes does it take to turn rocks into
igneous rock?
30What 3 processes will turn rock into metamorphic
rocks?
- 1. Extreme pressure
- 2. heat
- 3. hot liquids
31What 2 processes does it take to turn rock into
sediment?
32What 2 processes does it take to turn sediment
into sedimentary rock?
