- Rock
- is a mixture of minerals,glass mineraloids,or organic matter
- Rock Cycle
- showing the three types of rock and how they are formed
- Igneous Rock
- rock formed by the cooling and hardening of molten material from a volcano or from deep inside the earth
- Lava
- magma that evetually reaches earth's volcano
- Intrusive
- igneous rocks formed when magma cools below the earth;generally have large mineral grains
- Extrusive
- igneous rocks are formed when lava cool on or near the earth surface
- Basaltic
- igneous rocks are dense,heavy, dark-colored rocks that form from basaltic magma
- Granitic
- igneous rocks are light-colored rocks of a lower density than basaltic rocks
- Metamorpic Rock
- rocks that have changed due to temp.& pressure increases or that undergo changes in composition
- Foliated
- a type of metamorphic rock created when mineral grains flatten and lined up in parellel bands
- Nonfoliated
- a type of metamorphic rock created when mineral grains change,grow ,and rearragge;BUT DONT FORM BANDS
- Sedimentary Rocks
- form when sediments become pressed or cemented or when sediments precipitate out of solution
- Sediments
- are loose minerals such as rock fragments,minerals grains,and bits of plants and animals remains
- Compaction
- a sedimentary rock-forming process that occurs when layers of small sediments become compressed by the weight of layers above
- Cementation
- a sedimentary rock-forming process in which large sediments are glued together by minerals deposited between the sediments
- When magma cools what does it form
- intrusive ignegous
- folliated rocks have
- banding
- granite is a
- rock
- sedimentary rocks are
- often found at the earth's surface
- what are the pressure and hear that prouduce magma called
- radioactivity
- detrital roacks are
- made of fragments
- coal is used as fuel to produce
- electricity
- Burning waste coal with ___________ creates alkaline ash htaht helps lessen acidic problems
- limestone
- A rock is
- a micture of minerals, mineraloids, glass, or organice material
- crystals that form is slowly cooling magma are
- large
- how is a detril rock named
- the size and sgaoe of its sediments
- what forms granite
- mica, hornblende, feldsper, and quartz
- What does the process os congeneration produce
- electrical and thermal energy
-
T/F
Sediemntary layers are recognizable by differences incolor, sediment, size and compostition - true
-
T/F
All igenous rocks are formed in the same way - False
-
T/F
Nonfolliated rocks have very narrow banding - False
-
T/F
Metamorphic rocks can be formed from other metamorphic rocks - True
- In a network-tree concept map would basaltic lava be listed under instrusive rocks or extrusive
- extrusive
- In a network-tree concept map could you list instrusive rocks under rocks that form above or below
- below
- Shown on photgraph of pumice and one of obsidian how could you distingush between the two rocks
- obsidian is smooth and pumice is full of holes
- sandstone
- sedimentary
- limestone
- seimentary
- gneiss
- metamorphic
- obsidian
- Igeneous
- granite
- igneous
- slate
- metomorphic
- rock salt
- igneous
- How are rocks classified
- they are classified by thier formation and compostion
- Where does the rock cycle begin
- it has no beginning rocks are constantly changing
- Why is danerour for rainwater to flow through piles of waste coal
- the rainwater gererates acid runoff from the waste coal; the acid rain cause pollution
