  - beams
  - files
  - heavies
* are located in armies
  - houses

  - verticals
* come in all shapes, sizes, and colors.
* filters the blood of patients with rheumatoid arthritis.
* have a higher density than star crystals, and are typically smaller.
+ Abacus: Mathematics :: Mathematical tools
  * Abacuses can do addition, subtraction, multiplication, division, and people can use them to find the square root of whole numbers. Expert, or very good, abacus users can sometimes do math quicker than basic calculators. There is a common Chinese abacus. There are one or two beads in the top rows, and four or five beads in the bottom ones. Every column represents a different digit.
  * A 'column' in architecture is a vertical element that transmits the weight of the structure above to the structure below. Columns can be either a single piece or several pieces put together. Columns are frequently used to support beams or arches on which the upper parts of walls or ceilings rest.

### formation | column:

Ionic column
* Ionic Columns have scroll-like spirals at the top of each column.
* cylindrical shaft with a scroll shaped top on the shaft.

Totem pole
* are about cultural identity
  - emblems
  - family memorials
* is an emblem
* stand as tall as the nearby trees.

Coral formation
* are home to a variety of fish with the chance of sea turtles being sighted.
* occur in tropical and subtropical waters.

### formation:

Crater
* Many craters are present in the upland surface, but craters are few on the channel floor.
* More craters means oldest, few craters means geologically younger.
* Most craters have diameters
  - rim diameters
  - lakes form by water being trapped within a crater
* Some craters are formed by asteroid impact
  - explosions
  - have smooth rims
* are a good measure of how old a surface is
  - among the chief geological features of interest to planetary geologists
  - big holes that are made when meteorites hit a planet
  - circular depressions caused by the impact of meteorites
  - constellations
  - like the footprints of meteorites that crash from the sky
  - located in moons
  - one of the most interesting and important types of surface features in the solar system
  - small compared to calderas
  - usually of either impact or volcanic origin
  - visible on the surface of the nucleus
* can occur within calderas.
* come in all sizes, from micrometers to hundreds of kilometers in diameter.
* created by volcanic explosions are also quite common.
* dot the surface.
* form on planets and moons when meteors hit
  - when salt resists compression, mushrooms upward and collapses
* gradually accumlate on an old planetary surface like a sidewalk getting wet in the rain.
* is one of the world's seven marine meteor craters.
* lakes form as the created depression, within the crater rim , is filled by water.
* lakes in eastern Indonesia
  - particular are valuable indicators of the status of volcanic systems
* lakes, terrestrial degassing, and hyper-acid fluids in the environment.
* mark the surface.
