### rock:

Glacial ice
* absorbs all colors of the visible light spectrum except blue, which it transmits.
* has great competency.
* is full of sediment
  - the largest reservoir of fresh water on Earth

Granitic rock
* have uranium concentrations that are high relative to most rocks.
* represent the roots of ancient continental-margin volcanic systems.

Hot rock
* are never suitable for any pet as they provide a localized source of heat that is too hot
  - only effective when buried under the substrate an used as a secondary heat source
* provide a localized heat source that is often too hot.

### rock:

Intrusive rock
* come from magma.
* cool slowly because they solidify inside the Earth
  - very slowly
* form when magma solidifies beneath the earth's surface.
* have a characteristically coarse grain size
  - coarse grained texture
  - large crystals that can be seen with the naked eye
* help to built the volcanoes from the inside.
* occurs in a variety of forms.
* result when magma solidifies beneath the earth's surface.
* show a granodiorite trend, locally with a slight shift towards monzonite.

Jurassic rock
* are present in the subsurface of the western part of the state.
* have no outcrops in the area but they are identified by bore holes.

Kid rock
* Kid Rock supporter of people in the United States Military.
+ Kid Rock, Live performances: American rock musicians :: Musicians from Michigan :: 1971 births :: Living people
  * Kid Rock is a supporter of people in the United States Military. He has performed several concerts for soldiers, and gave soldiers free copies of his album 'Born Free'.

Larger rock
* broken off by sediment are called scree or talus.
* work best when they are flat and smooth.

Mafic rock
* are darker in color and denser than felsic
  - denser, with ultramafic rocks being the most dense
  - generally dark-colored
  - less dense than felsic rocks
  - lighter in color than felsic rocks
  - usually black and have abundant iron and magnesium
* contain more iron and magnesium than felsic rocks
  - silica than felsic rocks
  - roughly equal amounts of ferro-magnesian minerals and calcic feldspar

Mesozoic rock
* are dominantly carbonates with shales.
* contain more mobile types, such as crabs, snails and fish.

Molten rock
* can flow quietly out onto the surface as lava
  - rise up from the mantle into the crust and cool slowly forming big crystals
* has a very low resistivity, the cold dry hostrock a high resistivity.
* is said to have cooled and formed granite.
* surges upward along numerous vertical fractures.
* tends to stay molten much longer than it does here on earth.

Moon rock
* All moon rocks are basalts, anorthosites or breccias.
* are completely different from rocks native to Earth
  - located in moons
  - typically three billion years old or older

Oceanic rock
* are normally quite young deposits.
* is returned to the Earth's mantle when oceanic crust is subducted.

Pebble
* are all shapes, colors, and sizes
  - information appliances
* are located in aquariums
  - beachs
  - creeks
  - gravel
  - ground
  - lakes
  - meadows
  - playgrounds
  - ponds
  - riverbeds
  - shoes
  - streets
* are small rocks
  - stones
  - smooth because they are constantly being moved by tides and waves
  - the smallest type of gravel
* are used for looking
  - paving paths
  - throwings
* contain the same apatite variety.
* includes sections.

Precambrian rock
* are the first bedrock encountered in most of central Minnesota
  - undivided and consist of sedimentary, metamorphic, and igneous types
* can be complexly deformed.
* outcrop extensively in shield areas such as northern Canada and the Baltic Sea.
